Common Lift/Tire Combo's for OBS/NBS Trucks & SUVs

[slamchops]

These are only common lift/tire combinations that seem to work well together. Some setups may rub in off-highway situations, but most allow for clearance. Any wheel that is 'not recommended' for that particular height can be run, but is not advisable.

*Note:Thanks to those who double-checked everything and added more info.

[slamchops]

damn people, dont be too quiet. any comments, additions? HD guys get in here and add some info for the new 2500HDs.

[URBAN COWBOY]

Nice list, very informative.:head:


URBAN COWBOY

[EWogo]

How about some 2wd to add to the mix. There are plnty of lifted 2wd's on the site and I am sure people are interested to know that as well. Looks good though, very imformative.:rocking:
Evan

[slamchops]

Evan, if you want to do the honors that'd be great. i don't know the in's & out's of 2wd lifts like you do. ;)

[danez71]

Way to go Slamchops !

looks good.

The info is a GREAT place to start for people wanting to lift but dont have much knowledge about how much to get.

Now if we can only make a sticky outlining the differences and actual lift hieghts of the kits (spindle vs full drops, amount of front axel drop, amount of LCA drop, etc)...............

Good job Walter

[DSZ71]

Crap, nice list. My fingers would have fallen off from all that freaking typing!

Hey DaneZ71 - Got any pics of your ride? I am interested in seeing the 315s on with an RCD lift. Did you crank the t-bars or add anything in the rear for more lift? Any info would help. BTW, I had sent you several PMs, but with no response.

Thanks man, your idea sounds real good too. i was thinkin about that, but there's a lot of specs to deal with. should get a few ppl in on that one, it'd save us some time writing it all up. it'd be EXTREMELY useful with all the 'what lift should i get' threads we get. we could even have a user rating at the end of the listing for each one.

DS, thanks as well, the typing wasnt hard, i just did the list for the OBS and copy/paste to make a new list and just tweaked it for the NBS. ;)

[scottyb]

two thumbs up:head: :head:

[wolf10851]

dammit :banghead: I wish I had seen this list BEFORE I bought my tires I would have gone bigger than I did :LOL: nice list thank youhttp://

[00buck]

this is a very good post especially for all us newbies that ask these questions again and agian! thanks a lot slam chops for the info and anyone else that helped him out:D :rocking:

[BigBadK5]

the list is helpful. but its comon sense too. plus every onest truck sits a little diffrently my blazer had 33's stock, but my freinds rubed bad so just gotta try stuff out.:D

[chevyguy]

So let me get this straight. I have a 00 Z71 and if I get a 6" lift with 8" width wheels they wont rub, but if I get 10" width wheels, they will rub. Correct?

[slamchops]

what size tire? 35"? 10s might rub/might not rub, you might just have to crank a little to clear them, or you might have to trim a little plastic.

[woyster_00z71]

Nice list. However, I have a 2001 Tahoe Z71 with 17" wheels. What are my options?

Stock height, stock wheels.
3" body lift, stock wheels.
3" body lift, aftermarket wheels.

Thanks.

[RIFTED]

slamchops -

On my 97 yukon I have a 6+3 combo with 36x14.5R15 and I want to go th 38.5x15.5 R15x10 like tennesee did but mine rubs now.

What do I need to do? Is my backspacing incorrect or do i need to crank the T-bars? my angles look good right now. Or mabey a ball joint flip?Thanks

[slamchops]

what size wheel? im guessing 15x10? are you rubbing on flat ground wheel at full lock or flexed up at full lock? the best thing is to find out where you're rubbing, see how bad its rubbing and crank a little and trim a little, theres lots of plastic you can trim... just take it a step at a time, trim a little, still rubs, crank a little, still rubs, trim some more...

another good bet would be to PM tennessee and see what he had to do to fit those tires. that way you'll have a general idea of what to do, and what 'interferences' you might run into... ;)

[RIFTED]

Slamchops,

Thanks It looks like I'm Rubbing whem i'm at full wheel lock. I think if I remove my fender flares I might be ok. Or do you think if I change my key to a ferd key and then crank the t-bars i would be better off of just start cranking before I remove my flares?

[slamchops]

if your cv angles are good enough right now, i'd just crank a little, or maybe put in the ford keys and crank a little. then if you still rub trim it back...

['00SierraGuy]

How about some 2wd to add to the mix. There are plnty of lifted 2wd's on the site and I am sure people are interested to know that as well. Looks good though, very imformative.

Go for it dude. I would find it very helpful and i bet some others would too.:rocking: :head: :rocking:

[Z71mudder]

Im confused, how do we know if its a "true" lift or false lift or what not??:crazy: If ive got a 4", i didnt have cut out flares, and if its a 6" i didnt trim or crank the tbars?? Im confused!:crazy: :kidding: :D

Sorry, I had too! Great info slamchops!!:rocking:

[Josh]

Great thread!! I joined to learn things like this. Im going with a 3" body lift and 15x8 wheels with 32x11.5 tires. That should be as big as I can go without a suspension lift.

[cokedrvrbjw]

Im lifting my 02 2500HD in the near future whats the biggest tire i can run with a 6"lift and the H2 rims (17x8.5). 35"'s? Can i go bigger? Does anyone have any tire recomendations?

[slamchops]

the HD's have a little bigger wheelwells, you might be able to 'shove' some 36s under there, but 35 would be a safe bet.

[03SUB]

Just finished my body lift(3") on my 03 sub, and I am running 295/75/16's on stock wheels. No rubbing as of now. Thanks, Shannon

[HDMLNIUM]

Ok, How about for an 03 Sierra Denali? I have the t-bars cranked 6 full turn and it gave the truck an inch. They have at least a few more turns left before they bottom out so there is more height to be had. I was trying to level out the truck some but now I think I would like to make it a little bigger with some different wheels and tires.
Any ideas, I am from Maine so we can't go to big here or it won't be allowed on the street.:crazy:

Bill-03-SD

[tbyrne]

cokedrvrbjw: I run 35s on my '02 HD. 6" lift and cranked the bars enough to get close to 7.5" of lift in the front. I still had to do a little trimming at the corner of the airdam. Tires on this truck are 325/65/18s.

No, the wheel wells are the same. The difference is the H.D.'s frame is bigger, so it is like it has a 2" body-lift.:read:

[jessecarlson]

Hello,

OK - I think I have this whole backspacing thing figured out but.............................................


I have an '01 Silverado Z-71 with the original wheels on it. I installed FORD keys up front and bout myself 2.5 extra inches for about $50 total. I am thinking about 1.5" lift blocks in back, but don't think necessary.

What I need to be sure of are two things:

1- Can I put on 305/70's with this current setup on my stock wheels?

2- If I put on 1.3" thick hub adapters would this help or hurt my fit? I would assume it would result in less problems / less trimming but I'm not sure.

Any advise would be much appreciated.

Thanks,

-Jesse

[surferdude]

I'm wondering why you're going through all of that just to put 305's on an otherwise stock Z-71? I have 305/70R16 MT/R's on my stock 99 Z-71 with minimal t-bar cranking. I had the 305's (AT/S's and MT/R's) on the stock 16x7 rims with NO rubbing and only "minor" rubbing on the left front running 16x8 AR Atlas (4.5" backspacing?) - the wider rim helps the tire fill out more. Now I have no rubbing after running the MT/R's since March - replaced 305 GY AT/S's. I guess I'm just trying to save you some work and $$$.

[jessecarlson]

Thanks for the reply.

I did the Ford Key thing just because it seemed (after reading alot of threads here) the better way to go instead of just cranking.

I am glad to see you have had no rubbing issues even w the 305 MTR's - I do substantial hwy driving so will probably get a set of ATS'.

Sweet truck! - Mine is same color. I like the way yours looks w/o any additional lift in back / minimal in front. I think I will skip the lift blocks and go with what I have. I may even consider cranking down a 1/4 turn or so because when I put the ford keys in, my truck is about 1/2" higher in front than in back. I thought it would "settle" after a couple weeks, but no way.

I found out that the hub spacers actually make rubbing worse, so that'll save me a couple 100.

[surferdude]

Cool, Jesse, glad to hear you won't be using the hub spacer's! And I didn't know they cost that much!

[treyZ28]

One thing I did a search for and couldn't find-

what size can i fit with a stock 2500 HD?

also- pardon my newbieness-
what are ford keys?

[J to the izA]

hd's cant use ford keys. if you dont have them get green keys. there is a HUGE sticky about this. read it.

as far as tires, 285s on stock rims is my favorite

[treyZ28]

285/75/16?

I thought regular 1/2 ton LT could go that big. doesn't the HD have an additional 2'' of space?

[J to the izA]

with the shape of the fenders its hard to stuff tires in there.

yes half tons can fit them stock, but IMO they NEED ford keys at least. hence the two inches.

im not a fan of jamming the biggest tire you can afford into a stock truck. that southern style is fugly IMO and not practicle. on a stock HD you can fit a 295/75 but those tires are alot more $$ than 285's i think

thanks for answering all my questions jeff :head: (and not just this thread)

hopefully i can get this silverado i'm hoping for- but i need to see if the rebates in nov are the same

i was about 10 sec from handing the dealer the deposit check for a black ex cab 2500hd duramax/allison LS with tow package and bling wheels :D


then i foudn out in michigan sales tax would be on $35,000 whereas in NY (where i am from) it would be $13,000 (differance b/t trade in and new truck)

so now the battle plan changes:cussing:

[surferdude]

Big tires on a stock truck? A southern thing? WTF? Oh, brother. Well, this southern boy bought a used 99 with 305's already on it - in PA. So, aside from the ethnic stereotype, I like having 305's on my truck and I haven't had any problems running them with the stock t-bar keys.

cmon, dont even try to say that southerners are an ethnic group :LOL: thats a joke

i realize its stereotyping yes, but its really another talk show. the topic of tires is here.

305s will work, its all in preference, personal taste. i prefer the look of 285s to 305s. both work its just two different looks.

[surferdude]

Talk show? What a jackass. Have a nice day.

[geno96Z71]

I currently have 285's on stock rims and stock suspension. Id' like to step up to a 6" lift and 35" 's. I've been told that Pro-Comp lifts have some problems with ball joints. Any comments or suggestions for the brand of lift kit to go with?

Geno

[HDCHEVYMAN]

I have a 2001 2500HD and I fit 305/75/16 under my truck stock with no torsion bar adjustment and light trimming to the bumper. They were mounted on a 16x8 wheel. I now have a 8" Fabtech lift and a 3" body lift on my truck with 38x15.50 running on it.

A+ Dude!

[nebraskaz71]

on a newer hd with the 6-7.5" superlift what size would fit on 16x10 and what about if i had that lift plus cutouts?

[rjwms]

Did the 2WD drive guys ever speak up?

I have a 4 1/2" lift and I easily fit 305/70 R16. I should of gone 315/75 R16.

BTY... I have an OBS. It makes a difference.

[PaulSter]

Nice list. One note-- Fabtech's information says their 6" is recommended for 35x12.50s and 16x8 wheels. Not coincidentally, I'm running the 16x8s.:head: I did slightly trim the front bumper and air dam though.

PaulS

[Trory]

Awesome Info Slamchops! Helped me a lot...

[fierotoo]

Well for a NBS 2WD Silverado, stock height so far, I have 265 75r16 on there--31.8 inches diameter tires. I haven't noticed any rub yet, and all onroad driving so far.

Chris

[My1stGMC]

Thanks for the info. It makes it a lot easier for us newbies when somone with experience takes the time to do the legwork.

[autopat]

From all the Tire shops I've spoken to, they say 315's will fit on a stock height HD, with no mods. Myself, I'm going to go ahead with the green keys before I make a tire change! I'm also going with a 295/75/16 on 16X8's, with a possible upgrade to 315's later, I just wanna see how they fit first:D . When I first got my HD, I noticed it was almost the same height as the Yukon (next to it), and it's got a 6" RCD w/35's, so I figured the only difference (height wise) was the difference in tire height.

[baddassZ]

Hey Guys, I've got a 2001 Z-71, with 285/75/10 tires with stock rims and I'm thinking about getting a 3 inch body lift. Do yall think it will look good? Also I was wondering how big do 285/75/10 tires translate to like compared to 33's?

[Castle Killer]

285/75R16, I bet you mean, since that is what you list in your sig.

285s are about 33x11.50, 305/70R16 is about 33x12.50.
These are not exact-EXACT translations of the sizes, and different brands will differ from one to the other.

I would think that they would/could be a bit small with the body lift.
Your 2" lift is a torsion bar crank, correct?
I would think that if you are using your stock rims that 295/75R16 would look very nice (about 34x11.50, and thus better fitted to your rim's width than the 305).

[DblNutzSierra4x4]

What's the biggest size tires can I put w/ 16x10's on a stock 00 4x4. Right now I'm running 265 75 16's. I wanna put the biggest size w/o a lift.BTW torsion bars are cranked.Also when they say trim where do they mean?

[treyZ28]

anyone running a 32 x 11.5 (x16)on a stock ride height silverado?

I need new tires but expect a 2500HD in the driveway soon so i'd like the biggest tires i can right now and swappem later. Im more concerned about width that height because most of my offoading is at the sand dunes. Actually, all of it is- all that a stock truck couldn't handle anway -back ally/trail behind the house, feild and occasional curb (damn school! make the parking lot wider! if someone parks next to me, i cant get out!) Not a fan of the mud pits around here as its all tight trails and a body damage magnet.

Seeing how its going to be a heavy diesel, width is important to me.

[GMC HD 4x4]

Is there a lift that will let you run H2's 17X8.5's 5x5 back spacing ? Starting to get ideas ? If possable just 4".............



Thanks

BTW: slamchops nice job!! :head:

[bigmark76]

i am a 2 wheel drive guy with some questions. I just bought a 3 inch P.A. body lift for $150 for my 03 ext cab silverado. I wanna know if i can fit 305's with that lift and have no triming or cranking on stock rims?also will i need to add new shocks? and if so what kind

[black4x4]

I have a nbs z71 and was wandering if i could clear 38s with a 10" lift cranked to 11 and light trimming. and clear offroad when i play in the mud.

[slamchops]

prolly, theres guys running 6+3 on nbs trucks with cranked bars runnin 38s....

[forum282]

I have a OBS Tahoe stock... I wanted to put 285s on there when I get some new tires shortly. Anyways, I found the wheels I wanted except they are 16X10 with a 4 inch backspacing rather than 16X8 so I was wondering how big of a problem this would be? Would I need to do a lot of trimming and/or cranking or what? Thanks in advance.

[markhs2]

Your chart goes up to 98 trucks? Am I reading it correctly? What can I do with my 99 5.3 silverado z71 with 3.73 gears. If I want to off road, slow stuff, and be able to tow sometimes? Thanks

It depends on what you will be towing? Like how much weight is it? 5th wheel or regular ball and hitch in the rear?

Ya got to look about 1/2 way through the post. It will show ya but I copied and pasted for ya. :-)

I've got 16 1/2 x 9 3/4" Welds Typhoon rims on a 95 Burban 2500 4x4 with a 6" ProComp lift. I'd like to go with a 3" body lift, and I'd like to know what's the widest tire I can fit? According to Slamchop's list, I should be able to fit 38x15.5" tires...is that really true (not tryin to knock u Slamchops...it's just one of those expressions) I was told by a couple people that 12.5" would be the widest I could go with. I'd love to go with a 15.5" wide tire if it is possible, with/out minimal mods. Also, another newbie question here......what exactly are Ford keys and Green keys? And do I have them on my burban? Or is that on 99 and newer trucks/suvs? Also, what's with "cranking?" By reading the posts, I understand by "cranking" people have gotten roughly 1"-1 1/2" or extra lift....is this on my burban? What's with flipping the ball joint? and tweaking the t-bar? I've got a lot of questions, but I forgot what else I wanted to know...lol So I guess I'll end it right here.......TIA everyone! :head: :D

One more thing....lol....are there any other higher body lifts other then 2" and 3" lifts? And if so, are there any drawbacks to them? Roughly how much do the body lift kits go for, and roughly how much do they cost to be installed....Thanks again everyone!!! :head:

[jasonv]

i have a 2wd ext cab chevy and i want his the bigest tires with the least amount of liftwhat would be right . and i still want a smooth ride. what about 285's witha 2 in leveling kit

[punkoramaglory]

I've got a 1980 Silverado 1/2 ton 4wd with a 4 inch rancho suspension lift. I have 33x12.50s on it now and it doesnt seem to quite fill out the wheel well enough so i was thinking about moving up to a 16x10 inch wheel with 35x12.50 tires. It looks now like theyd fit with no problem but ive also read that this combo might rub a little so i was wondering if anyone has tried a similar install before with that general body style? (1973-1987), and if really major cutting of the fenders was needed.

[chevyguy]

Great thread

[superZ-71]

i was wondering if anyone has a 4" lift on a obs z-71 and 35" tires. would they rub, if so could i just trim the front valance or would i have to cut the bumper to? :think:

[Rowdydowdy04]

what about 04 silverados?
I don't have a lift, so I'm guessing the options would be the same as the 99-03 you listed?

[desertdave]

I just bought a 2000 2wd ext. cab silverado last week. Planning a 3 inch fabtech spindle lift soon. The guy at the place I plan to have the work done recommends 16x8s with 285/75. I'd like to only go with a 265. Any opinions on how that would look? Also, any word for sure on if I could use the stock 16x7 alum rims with 265s and not rub with that lift installed? By the way, great site...I've gone from knowing 0 about my new truck to knowing enough to be dangerous in less than a week.

[jasonv]

no, you cannot use the stock wheels. thay will rub the spindle. you need more backspaceing.

[desertdave]

Thanks Jason, that seems to be the answer I get most. I like the look of the stock rims, but I also like the way rims with less inset allow the tires to fill out the wheelwell better. Aftermarket it is. Big 0 installation guy had a pic of a truck just like mine with the 3" lift and 285s and it looked pretty darn nice. Any thoughts on 285s vs 265s on a 2wd with just 3" of lift??

i would go with 285. you might me able to get wheel spacers to use the stock rims. but i 'am not sure. i think it would work

[Castle Killer]

Look up Germinator's truck, desertdave.

[Rescue 1]

All the info here deals with 16's. How about 17's? Looking to see if I can put 285/70 r17 GoodYear MT/R's on stock aluminum wheels on a 2004 Z-71. Will it fit stock or will I have to lift it. If so how much?

[slamchops]

17s should be pretty much the same as long as the outer diameter of the tire is the same. ;)

[Greek]

Now, there hasn't been any talk in this thread for over a week now. I never really got a feel of what people are using on 2WD's. My truck is in my sig. and what I'm thinking is just getting a pair of green keys and some new longer shocks for the front end to level it out and possibly some 285/75/16. Does this tire size sound too small or just about right? Will my ride suffer or will it be a mistake to put some green keys in and crank my tb's??? Any and all help is appreciated...Thanks!

[geno96Z71]

Greek,
I'm assuming your rig is a 4x4, in which case you can go with the 285/75R16's on stock rims and it should be no problem. I have 285/75R16 BFG A/T's on stock rims on my '96 Z-71 and they fill the wheel well nicely. My truck is stock height, and doesn't appear to have the torsion bars cranked. The only thing that bothers me about the setup is the backspacing on my stock rims (wheels tucked in abit too much)- gonna get some 16 x 8 589 Eagles and fix that soon.

Hey Geno,

My truck's actually a 2WD (unfortunately) and the front sits a couple of inches lower than the rear is why I want to even it out. I've heard that 285's will be just right and I'm thinking about some 16X8's like yourself...

[geno96Z71]

Greek,
I've heard that even the 2 x 4 HD's actually sit a little higher than the regular 1500's, but I would be surprised if you could get away with 285's. I don't think you've got torsion bars on your truck (4 x 4's do though)- pretty sure it's A-arms w/ a coil spring. Fabtech 3" spindle kit is the least expensive way to get those 285's on, but you'll need 16 x 8 rims w/ 4 3/4" backspacing (stock rims won't work).

Thanks for the info. Geno. Yes, the HD's sit a couple inches higher than the reg. 1500's but I didn't know that about the front suspension. I read somewhere though I could be wrong, that they did have torsion bars. I haven't been under my truck yet but I'm going to now to see if there are torsion bars, if not, I have to spend the cash on the spindle kit I guess, that's if I decide to keep it now, lol.

Thanks again...Jimmy

[geno96Z71]

Greek,
It cool to have a 4x4 , but in reality I don't use 4wd much (not many logging trails in South Pas) and I bought the truck for work. But it is nice to know it's there when and if I need it- and I do plan to wheel it eventually.

Fabtech's 3" spindle kit is around $400 and you have to spend another $1300+ for wheels/tires, but then you've got the look without the liabilities of a 4x4. Fabtech also has bigger 2wd lift kits if you ever feel the need to be lifted.

I'm in Pas. pretty freq. myself but I wouldn't go there for any offroading, lol. I go hunting quite a bit and have never had the need to use 4X4 but just in case as you mentioned, it would be nice to know it's there. I've got someone possibly interested in my truck and I'm considering it. I think I'm going to list it in here as well.

Yeah, Fabtech has some really nice kits for the 2WD so if I keep it, I might go that route.

Thanks bro...Jimmy

Greek,
What are you considering as a replacement? I would step up to a 4x4 3/** Duramax ECLB in a heartbeat if I could afford it. But I got a good deal on my rig when I bought it and it is a Vortec, so I think I can live with it and have fun souping it up too. Keep us posted on the outcome (if you get a 4x4).

Cheers,

For a replacement I can't afford anything fancy at the moment as I'm working on my house but something decent. Maybe a 99-02 1500 5.3 4X4 or Z71 extended cab. Might have someone that wants to trade me their '00 Z71 for my truck but we'll see. I'll keep you posted...

[geno96Z71]

Taz,
I just bought the same tires from Discount Tire too- saw a pile of 305/70R16 A/T's there but stuck to the 285's to save on the mpg's. But I admit that they would look better, especially with the 3" b/l. But if you really need to go bigger I'm sure you could find a buyer- the 285's are a popular size.

Greek- I like the 99-02 ECSB Z71's too- better engine (5.3), 4 doors, 4wheel disc brakes, etc. But I'm still thankful I have the truck I have- I'm sure there are plenty of guys out there who would really be happy w/ a OBS 4x4. Judging but the popularity of the OBS trucks, I'm sure I could find a taker when I decide to upgrade too.

Yeah, but I bought rims too.... Cost about $100 to mount tires. Cost me over $900 for the rims/tires set.

Just have to wait til I need new ones...

[geno96Z71]

What kind of rims did you go with? I'm thinking about going with a set of 16 x 8 1069 Extreme alloys- any thoughts on this? Gonna be a long wait (depending on your mileage) on those BFG A/T's- they wear well.

Geno

[taz104]

Actually went with "Dominator" brand A/T 285's. Bit less expensive than BFG's....better fit in the budget. Pretty happy with them so far!!!

[geno96Z71]

Taz,
I should have figured that one out- a set of BFG A/T's on basic new aluminum rims usually will set you back at least $1200. The A/T's weren't cheap, but I can't think of any other tire that wears like it. I've already put 800 mi. on the new rubber and it still looks brand new.

Geno

[taz104]

Got it for $915 out the door. That's including the same 50k mile warranty that comes with the BFG's, which as you said would have ran a bit over $1200, plus tax...7.75% here in Cali.
The set I went with was the most bang for the buck, with the same warranty and Discount Tire guarantee. Can't beat it.

BL is your cheapest option...takes about a weekend to do it yourself the first time if you have everything you need. Took me 3 days cause I had to get new body bushings.
Could get a bigger suspension lift if money is not a question...

Would you happen to have a check list of tools needed to do this? I have a 6" Fabtech kit on the way and thinking about doing a 3" bodylift. I would be doing this probably with the help of a friend for the first time and although I'm pretty mechanically inclined, I've never done any of this kind of work before.

This site (http://tommy3z71.homestead.com/body_lift~ns4.html) will provide you with some help on an NBS truck. Other than that, try searching Bodylift on the forums. Basic handtools...power/air tools make the job simpler, faster, and easier.

ok so i have 6" and 3" combo...running a 36x14.5 on a 10 inch wide wheel with no rub...could i squeeze a 38.5x15.5 with out trimming anything?

[bad-ass-95chevy]

Im sure everyoen already knows this already, but with a fabtech 6" susp. lift, with just 16x10" rims, 35" tires, rubs liek crazy even under turning on or off road. I have a very shredded and unhappy toyo off read tire that is wearing the scars. The best thing i did to fix teh problem which worked, was cut notches in the front bumper and cut the fender out alittle. It works well not and not had any problems afterwards. Just tryin to save someone soem money, everyone knows by now, tires aren't cheap!

[bad-ass-95chevy]

nice list, what about: 325-16 (37" on 16's)???

NBS Trucks (99-03), NBS SUVs (00-03):

9" Total Lift (6" Suspension Lift + 3" Body Lift)
- 315/75R16 on Stock Wheels, 16x8, or 16x10
- 36/12.5R16 on Stock Wheels, 16x8, or 16x10
- 38/15.5R16 on 16x10 (torsion bar crank and heavy trimming)

[Tmo783]

just wandering. i have a 2 door 95 tahoe and am interested in putting 315/75/16's on. even if i cranked the torsion bars high enough would the back rub? Would i have to put blocks? i am a cheapscape and dont have enough money for a lift.

[4x4K1500]

would anyone happen to know if I could run a 305/70/16 on a 16x10 on a stock '68 k20???

[autopat]

The biggest problem I've noticed, is with the 10" rims, if you drop to 8's those rubbing problems almost totally disappear.

Why isnt a 16x10 recommended on stock height 99+?

[Boosted]

94 1500 4WD. Putting 9.5" FT lift and maybe a body lift. W/O body lift can I clear 38.5? Also what backspacing for 16x10 rims?

[79Shortbox]

Hey guys, I am new to this forum, this thread came up when I was doing a Google search about lifting my truck. I am planning to lift my truck soon. It's a 97 7Z1 1500 Ext. Cab shortbed. Currently running stock rims, 275/70 BFG ATs that rub when offroading. Anyways, I was going to run a 6 inch suspension lift all the way around. I was thinking about RCD, anyone have pros, cons, or a good alternative? I wanted to run 35x12.50 BFG MTs on 18x10 rims with 4.5inch backspacing. Will I have rubbing issues? And I feel kind of lame for asking, but what does the rim height have to do with rubbing issues? Like, say instead I ran 16x10s with the same backspacing with the same size tires, would I have the same problems that I would with the taller rims? Thanks for the advise ladies and gents, this seems like a great forum, I might stick around. I am a regular over at Chevy Talk. Oh yeah, I am in Pasadena, I don't know I saw some of you talking about Dena earlier. Thanks again folks.

[AZ4x4Chevy]

I just ordered 315/75/16 for my '02 2500HD. i have no lift. i cranked my t-bars all the way and got 2 inches. i trimmed a ton of plastic and took it down to discount tire and had them mount a BFG AT on my stock wheels. squeezed them in. cranked the wheel both ways trimmed a lil more. they looked awsome but i wanted Nitto Terra Grapplers instead so now i'm waiting for them. The 1st discount tire store i went to refused to even try the 35's on there, so i just called around till i found one that would humor me and mount them so i could see. I was told by someone on here, that has them, that the mud tires occasionally rub on the suspension bar so i got some AT's.(dont have the huge side lugs) I'm getting them on tomorrow. i'll post pics so you all can see how i crammed them on there. the only way i think they could rub is if i hit bumps with the wheel fully cranked, but that wont happen too much i dont think.

[79Shortbox]

I just ordered 35x12.50 R16 BFG MTs and a set of 16x10 Mickey Thompson Classic IIs. Should be at 4WP tomorrow. I can't wait! I am going to hopefully get my lift ordered up tomorrow morning, see about getting it by this weekend! BOOYAH.

[treyZ28]

does anyone know stock wheel offsets?

[1988ChevyBoy]

You missed the 2" body/suspension... 33x12.50-R15 fits... as well as 285/75R16's... stock rims and 15x8/16x8 not sure about 15x10's or 16x10's but they should clear... i'll find out.

[1988ChevyBoy]

Oh sorry, depends on offset as well... it'll require very light trimming... just remove a bit of your bumper... for 88-98 vehicles.

[boosted1]

hey all i just joined this list and have read alot of great info
i just bought a 2000 3/4 long bed 2500 2wd silverado and would really like to lift the front to level it out with the raised back end, i was told that when i level it out i will be able to get 33 tires on it all the way around? now what i have found out is this, my options are....
lift spindles which seem very expensive
crank on the torsoin bars
then i hear something about ford keys

can someone please tell me what to do
this is a truck that is just around the house i got a great deal on it and it looks like new

would love some info
thank you all in advance

[AustinZ71]

Any info on what tires will fit on a '05 crew cab Z-71 with 17" wheels ? I have been trying to figure out if I can go with a 295/70/17 without messing with the torsion bars

[OlemissRebelZ71]

I know that with any suspension lift, before buying wide wheels like 10" you should check with them to make sure the wheells wont cause premature failure of certain components. I know pro comp says no to 16x10s and 15x 10s they say the max is a 8" on their 4 inch setups for gm ifs

[Woodster72]

Austin, I too have a 05 Z71 Crew Cab but I had a 3" body lift installed. I'm trying to figure out what is the biggest tire I can install without cutting or rubbing problems. Some say 305/70/17 should be ok but that is not a huge difference in terms of size especially for the price of tires. I would like to put some BF Goodrich 315-70/17 T/A KO's on but am afraid they might rub. I did post a question under the Exterior forum and am getting responses.

[IMPALAMAN1]

JUST CONFIRMING

305-70-16 on a 16x10 will fit a 2001 tahoe with a 3" pa bl
ill post pics when i figure it out.

[LiftedWhite94]

could i fit 37s on my truck? its a 94 with 3" bl and torsons up in the front and add a leafs in the rear. it clears the 35 x12.50/16s with no problem and the 37s are 12.50 so there the same width as my 35s and i dont have nothing trimmed either, so im thinking the 37s would clear i might have to do a little trimming, it has room to spare with the 35s...

[IMPALAMAN1]

NOT SURE ... HAVENT TRIED IT... IF YOU THINK THEY CAN CLEAR..... GO FOR IT... every body i talked to said no way..... until this site... then i decided to go ahead and try it. had to trim some but not alot.. mostly plastic parts... and it looks bad ass.

[rideinmychevy]

ive been looking but i cant find it i have a 05 will 16s fit? and if not whats the biggest tire i can put on my stock height 4 wheel drive? do they make a 285/75r 17? thanks

[macojoe]

Ok I have just bought a 02 Chevy 4x4 z71, Its got to be the lowest truck I have ever owned??
I have 265 75R 16 tires on it, they are brand new with 500 miles on them, installed from the dealer.
I tow a 30 foot camper that weights 6000 pounds, and a 4000 pound boat.

When the camper is on there it sags some, and I would like to lift the truck. On my 90 Blazer I added a 2 1/2 lift with solid wedged lift blocks and that was fine.

On thiks truck it seems low to me and i like to have my trucks high. So what is the best way for me to get this truck up a few inches and stasy with the tires I have.
I guess i want to add a supenision lift not a body lift. I have read alot here and I am confused about ford keys, and how much to tighten the T bars.
By tightening the T bars how will the truck drive? Will it get real stiff and bounce around??

Thanks all for putting up with all my questions, I am sure there will pleanty more before I am done with this project!!

[rideinmychevy]

anyone know if 16's will fit on a 05 sierra? or do i have to get 17's because of the brakes or what ever thanks alot

[macojoe]

I have also heard that Z71 has some kind of package in it so that you no need the ford keys, just crank it up to were you want it??

[VerticalOne]

I have an 01 Z71 Suburban , right now it is on 22's but everyone here has big rims. I want to lift it with either 18's on 35"s or 20's on 37"s... I need to know what lifts work well and what I can clear. Will a 6" clear 37's with minor trimming or would I have to add body lift.. I won't 4X4 it much, just pull a toy box and daily driver type... Please help If you can :rocking:

[cokedrvrbjw]

do they even make a 345/60/16 :confused:

I'm assumiing its a 16'' wheel?

a 345 is a ****ing massive bitch. I doubt you'll fit anything more than 305. I have 305s and they barey fit.

[black4x4]

for the record you can clear some 36x14.5 tires on a nbs on or offroad with 7"s of lift and cutting.

[chevy_man]

Hey guys, have any of you used Tuff Country or BDS lifts? One of my friends works for AFW here, which builds $50,000 and up custom jeeps. He uses both brands for the most part, unless you want something else or he custom builds it. I'm planning on a 4" Tuff Country for my 88 1/2 ton reg. cab, but he has only done jeeps and a couple fords, so I was wondering if anybody on here has used it. If I do run it, I'll go with 305's on a Dick Cepek FC-II on aftermarket rims.

[wreedZ71]

Could i put a 17x9 wheel on a NBS z71 without rubbing? its is stock height.

[sdwhitney]

Let me start by saying I am not the most handy with mechanics...

Ok, with that said, I have reading so much on the cranking and ford keys to level the front. I am not a do it yourself kinda guy(see my first line of post) beause I usually break something. So I called a 4wd place here to see if they would do either of these for me, and they said they have a leveling kit(probably new key and torsion bar cranking huh?) that they could install for about 220 including labor. That was easy enough, so that will be done this week.

I would like to stuff BFGoodRich M/T Ko's 305/70/16 (33.1x12.2) and some new 16X8 Wheels.

When there is no lift, do I have to worry about backspacing, or can I just get any wheel? And what about trimming, if I rub in the fender well, how do I trim, or shall I say, how do I get another to trim? Is there a website that shows instructions?

Thanks so much for your answers, and all the info I have learned from this forum allready!

[chevy95w]

I have a 95 z71 with a 3" body and 33/12.50/13 procomp xterrains. I am buyin a 6" suspension lift saturday and cant decide to keep my 15x10 in rims or go to 16x12. Also which tire should i get the 37/13.50 pro comp xterrain or the 38/15.50 SSR. Any help would be great thanks

[gmpartsdtingl]

:cool: so if I understand the start of this thing, I can clear a 285/70R16 with my stock wheels on my stock height truck with nothing but some torsion cranking? Or do I even need to do that? My truck looks like it sits WAY low in the front to clear a 285?

[tomshouse516]

what about 37"x12.5 or 37"x13.5 on OBS

[Chevyluvr]

New to the Site,
I didn't see anything on here about 2006 2500 HD 2wd.
I wanted to know some of the tire to lift Combos that I could do.'
Any info suggested would be greatly appreciated

[Buckhvnter]

slamchops - I have a stock '04 Silverado with stock 17"s how big of a tire can I go with? How about with and without a lift....say 3" lift

[Sub-Par]

Looks like I'll be the first with this combo:

99 GMC Sierra 1500 Z71, stock height. Going to run 33x12.5x20 Toyo open Countrys on 20x10 MB Motoring Smooth wheels. I guess I'll start with the Ford keys and see if they'll clear. I want to avoid a body lift at all costs, and all of the leveling kits and such I've found so far tell me the 10" wheels won't work (they all specify 16x8). I imagine with it being a 20" wheel it might offer more clearance around the suspension but I'm not so sure on the torsion bars or air dams. Anybody got some guidance or am I the first?:fsg:

[meltdown]

I have a 2005 2500HD diesel crew 4x4

I got green keys and 2" blocks in the rear.

What size tires can I fit??

thank you!!

[Nick76]

I have an 03' 2500HD with a 6" suspension lift and running 35X12.50's right now. Im thinking of adding a 3" body lift and was wondering if I'd be able to run a 36X15.50 tire??? If not, what about a 37X13.50?? Also, could I run these tires on a 16X8 rim?? If its for steering clearance, I might be ok because my suspension lift is a BDS knuckle kit that puts my front tires out about 2" or 3". I noticed in all the Mickey Thompson and Dick Cepek ads, they sell tires this size on a 16X10 wheel.

[HI85WH1]

8 pages and nothing directly related to my 99 NBS 2500 4x4.

The truck is currently stock height, but am looking for a change. My limitation is that wifey drives the truck from time to time and it needs to fit in the parking structure.

FWIW, I believe the front track width on the 2500's is wider than that of the 1500's. The stock 16's are barely inside the fender flare, and if I go wider, the fronts will stick out. (Hawaii Laws Suck Big Time) as the flare must cover the entire tread surface of the tire.

any help?

[uplandhawaii]

Another Hawaii guy, what island are you on?

[HI85WH1]

Another Hawaii guy, what island are you on?

O'ahu... I see you are on the big island...

[uplandhawaii]

I'm not real sure but couldn't you use green keys to level it out and run some 305's? I don't have first hand experince with the 2500's but I think that would work. Run some after market rims 8" wide maybe to keep it under the flares.

[HI85WH1]

From my calibrated eyeball, 8" rims will not fit under the front flares, as the stockers sit right on the edge already.

IIRC, Hawaii County still does not require recon, but Honolulu County does... so the tread of the tire must be under the flare.

I'll try and snap some pics from the front, with a straight-edge against the tire and up to the flare for reference.

[uplandhawaii]

Yeah no recon here but they still enforce bumper height and tire width. I just had my safety check done and had to use lawn edging as flares to cover up my tires.
Got any pics of your truck?

[Nick76]

Ok, I changed my mind....Im not doing the body lift. So with a 6" suspension lift and Green keys with torsion bar crank on my 03' 2500HD would I be able to run a 35"X14.5" tire? And would I have more clearance on a 16X8 or 16X10 rim. I'd rather run the 16X8 if its possible.......BTW, I got a BDS knuckle kit which already puts my wheels out 2-3".

[HI85WH1]

Nice looking truck. A little lift and some rims and I'd call it done!:D

[HI85WH1]

Nice looking truck. A little lift and some rims and I'd call it done!:D

As long as it fits in the wifes parking structure at work...

If I level it out, a set of 16x8 Alcoas or Welds with 265/75 Load Range E tires and I'll be good to go... the 245/75s are too thin for my taste...

'05 2500HD 4x4 here and still clueless to what I can fit. If I tighten the TB's some and keep the stock wheels...HELP?
- 305/70R16 on Stock wheels or 16x8 (torsion bar crank and light trimming); 16x10 (torsion bar crank and heavy trimming, or cutout flares) <--is this for 05HD's also ?
this was close as I got... and still no pic's


I just ordered 315/75/16 for my '02 2500HD. i have no lift. i cranked my t-bars all the way and got 2 inches. i trimmed a ton of plastic and took it down to discount tire and had them mount a BFG AT on my stock wheels. squeezed them in. cranked the wheel both ways trimmed a lil more. they looked awsome but i wanted Nitto Terra Grapplers instead so now i'm waiting for them. The 1st discount tire store i went to refused to even try the 35's on there, so i just called around till i found one that would humor me and mount them so i could see. I was told by someone on here, that has them, that the mud tires occasionally rub on the suspension bar so i got some AT's.(dont have the huge side lugs) I'm getting them on tomorrow. i'll post pics so you all can see how i crammed them on there. the only way i think they could rub is if i hit bumps with the wheel fully cranked, but that wont happen too much i dont think.

[03z-71]

Sorry guys for late arrival to this thread! I am looking around for some new rims, and i am going to be getting some 33x12.50R17 MTZ's after christmas. I have just installed my add-a-leafs, and my ford keys with the TB crank. So, i found some 17x10", 4.65" backspacing -25mm chrome MB Gunner 6 rims that i am thinking about getting. I asked the guy on here the other day wether or not those rims would stick out too far, because I don't want them way beyond the stock flares, and he thought that those rims would stick out level with my stock fender flares.

So, my question is will I have lots of problems trying to get the 33x12.50 and the 17x10's to fit? Or should i just stick with 17x9 or 8?

[ladukeja]

What an excellent thread!!!

I have a 2wd truck, in my sig, and I would like to put it on 33X14.50R15 Swamper SSR's. I think that the best rim for these is a set of 15x10 or 15x12. I have access to a 15x8 set, but I don't think it would look right, and it might be dangerous.

Does anyone have any suggestions for lift and what it would take to get these tires to fit? I didn't specifically see that particular size in any of the fitments above. I can guess what I would need, as I read the previous posts, but do you guys think that 7 inches of lift would do? Probably more like 9 inches, but if anyone, even a 4wd truck is wearing these, I would greatly appreciate any help. If the tire is impossible to fit, then I shouldn't be looking for such a crazy tire. I understand that as the tire gets wider, the outer edge of the tire gets closer and closer to the bottom of the bumper and the bottom of the rear of the front fender. I want to be able to float on top, not sink down when I go wheeling. :) Plus, it would look sikk!

Just an fyi, I am fitting a 31X10.50 on stock 15x7 wheels and I have some room for a 32X11.50 on the same wheel. I am at STOCK height right now.

Also, btw, for a lift, HAS ANYONE USED 3/4 TON COILs to lift their OBS truck in the front? Thanks again.

[Cagraffwriter]

I have a 2002 Sierra 2wd 1500. 18" of total lift on 39.5" tires. I dont have any rubbing issues, nor did I have to trim anything.

OK I have read every post on here and still have yet to figure out if there is any way to run 315's on a stock truck with out BL(I have seen some in sig's but no post to what all it intailed). I have a 00 RCSB Z71 with 285 BFG A/T's right now and want to go bigger. I have a set of ford keys and I don't mind turning the bars or doing a little trimming. Also is there anybody with pictures of this set up or any set ups with the key and 295, 305, or bigger. I just want it to set up higher and fill out the wheel wells. Thanks in advance guys awsome site :10:

315's will fit I had to do very minimal trimmning (3" piece of plastic fender lining)on mine to make it work! 315 only wind up being about 34" tall...

I am having a little problem with the conversions because I don't have 16's can someone help me?

I have 04 HD with 285\60\18's on 18X9 wheels. I think I am pretty muched maxed out as it sits now. So either I crank the bars a couple inches OR do a small lift. Don't mind trimming a little bit either.

So with these 18X9 wheels how big of a tire can I go:

With cranking the bars?
With a 3" body or suspension lift?

Any help would be greatly appreciated!

[stevefendt11]

I got a 4" lift with 33's on my 2003 2500HD and I still had to do some trimming on the front bumper. The reason is because of the large bumper on that body style. 35's would fit but I would have to do a little more trimming on the front bumper

I was just told my 2001 HD would not safely run 305's, then I searched and found this thread so I'm adding to the confusion.

I have a friend with 35x12.50s on his hd with a good tb crank. I dont see why 33s wouldn't fit.

[Chop Top]

Okay I talked to a good friend who runs a tire shop and he said it like this:

On the factory aluminum rims, yes the 305's fit with slight trimming and a TB crank. They outcome is that they are a little fat for the rim, and might pop off under alot of pressure when 4 wheeling. Also the tread will wear much much more in the center of the tire than on the edges nad you will have premature failure and excessive/accellerated wear. But yes, they will fit and look good.

He suggested I go with a 285 due to the fact that it's not quite as wide at the mounting point, and also you're only giving up barely an inch in clearance from a 285 to a 305 for most of the popular mud tires.

Awsome thread. i'm looking to put a few inches under my 01 2500hd and i think the 295s will look good. anybody with that model is more then welcome to message me and give me ideas of stuff to do for as cheap as possibe but still goo quality

I have a 2002 Z71, I have 2" lift rear (from adding 2500 springs) and cranked T-Bars.
I am running Cooper Tries that came on the truck, and they only have 20,000 miles on them and the front tires are already crap!
I just rotated the tires and had front end realigned.
I am looking into some taller tires, by what I have read here I should be able to put 295/75R/16 with no problems. I do a bit of towing and more road driving then off road. And the snow here in the NE sucks! So I like the look and traction of ATV tires.

So this leads to my question, Whats a good tire, ATV, AV, ATS to fit my need, and what brands are Medium priced that wear well ??

My old Blazer (full size) had Bridgestone Dueler's that wore like Iron!

What would you guys recommend?? Thanks Guys!!!

[David Stockton]

Hey my buddy just picked up a 2005 2500 HD. What lift would you guys recommend for desert drivin. Nothing too serious, nothing too big. He just wants a clean lookin truck that will handle if need be. Preferably to handle 33"tires. Any tips???

[AZ4x4Chevy]

I'm trying to figure out if i can fit 16x10 wheels with 315/75/16 tires on my 2002 2500HD? I currently a 3" body lift, tbars maxed and tons of trimming. I fit the 315/75/16 on my stock wheels without the body lift just fine. So I added the body lift so i can get wider wheels. I want 10 inch wide wheels so when i add a suspension lift they will accomidate a wider tire better than an 8inch wide wheel. Does anyone know anyone that has an HD with this set up?

Hey all, lot of good onfo on here.

I have a lil problem perhaps someone can help me with,
I have an '05 Chevy crew cab dually with an RCD 6" lift, stock size rim's and 315/75/16 BFG AT's with a 2" spacer between the duals. Empty, there is about 1/2" between the tires. I bought a camper and put it on and the duals are touching. Not good. I also pull a 24' TPD and have had no issues just pulling the trailer which puts 950 lbs on the hitch.
Took camper off and am now looking for a 35" tire that is only 11.5" wide, in a load range E or even a D. Cannot locate anything other than the Buckshot Mudders, yet they are only 9.5" wide, are very loud and wear too quickly.
Also, have no clearance issues even when running hard into the Dunes pulling a 9000 lb trailer.

used to work at discount tire we had a problem with dually's like that....have you looked at aftermarket wheels??? if you were lower id recomend 255 85 16's 33 1050 or so

315's are closer to a 34 anyway maybe trying a different brand of tire thats narrower...tirerack has a great specs sheet

also how much air are you running in them....the less air the more foot print ...I think that most e or d range you run about 80 psi....maybe bump it up a little....discount tire wont work on spacers....

[PROENGINEER9876]

I have a 2000 4.8 Regular Cab, Long Bed Silverado 4x4. I just recently put 285/75/16's on the truck. It rides good, but I want to throw some 33x12.50's on there. Am I able to put them on the truck with stock suspension as long as I crank the torsion bar all the way up or am I gonna have to get a 3" body lift and then see if there's any torsion bar adjustments from there? Thanks.

[makspringcole]

Lots of great info, unfortunately could not find what I was looking for.

I have a 2005 1500HD 4 door and was wondering if I can put 285/75/16 without any mods?

first of all, KICK ASS TRUCK! and check interco.com (super swampers) they have a wide variety of tires and almost all their tires wear really well

[Racking9398]

I have a 98 GMC Z71 with 285/75/17 cheapy Mastetcraft AT's. I think the rims have a 4.5 backspacing not real sure though. Could i put 33/12.5/17 MTZ's or Mud Grapplers on it. It doesnt rub at all now, but by not by much. I know i would i have to trim.

[big burby]

315 's stock just cut away any extra fender or inner fender the factory carelessly left on there:10:

[silveradoguy98]

Hey, I've got 2" blocks in rear suspension and cranked the torsion bars all the way to level it out and a 3" body lift. So, basically it's a 5" total lift. I've got 17x9 rims. Whats the biggest tires i can fit without rubbin?

[87-2-95Z28pa]

Nice list if I am reading that list right i have a 97 Tahoe at stock height i could go with 32's. If that is correct i could just go with 31's like i wanted to. I would be getting 15x8 rims.

Thanks.

[85gmac]

does anybody know what the biggest tire i can fit on a 03hd with a 20x10 inch rim by just cranking the torsion bars?

[TAHOE GUY]

I'm ready to buy same new tires next week. I would like to install 305/70/r16 on an all stock 4wd obs Tahoe, but not sure if it's going fit with out rubbing. But, if it's little triming I will go for it. I'm wondering if there is anybody who has GFgoodrich all terrain tires and 305 tire sizes on their obs truck or suv right now and can provide me with few pictures. If not I'll just go for 285/75/r16. THanks:stir:

[superlite]

tahoe guy I had 33's 305 on my 95 tahoe before the lift all ya need to do is crank the torsion bars and align it ya should be good after that maybe a small block in the rear if it isn't level

[TAHOE GUY]

Thanks superlite, how did it ride after the torsion bars? Was it a hard ride or wasn't not much of different? Anybody else have any suggestions. Thanks

sweet ride...

there are several companies that make spcers for between the rear duals.

[Dean-]

ok guys, I am lookin into buy a 96 chev, 4WD. The question is, can you do a simple front end lift of about in inch using the torsion bars just to level out the front rear height? My dad lifted the front of his truck an inch or so using the torsion bars, just to level out the height. So my question really is, does this truck have torsion bars, and is it possible to do this on this truck? How hard is it? I did it on my friens Nissan hardbody, and it was just a simple adjustment. Is it nearly the same? Sorry about my non-knowledge in this department.... any help would be great!
Thanks-

[Dean-]

Hey guys, I just got my 96 chev 4 by 4. I got some 35's on 16 inch rims yesterday for a killer deal. I am going to crank the bars up in the front, will these new wheels and tires fit? If I have to do some trimming I am fine with that, just want the nice look. I will be doing a 3' body lift soon, but just want that beefy stance for now.

[snowandtorque]

I have 33" on my 2500 suburban with 2.5" readylift keys and 2" rear block and my tire still rub :-(

[overdrive]

Hey...I think I just made a mistake...I just ordered a set of 35" tires (315/75/16)which sit 34.6 inches high, and 10 inches wide.. on a 16" rim...by installing a levelling kit, and cranking my torsion bars, and putting a lift block in the back, are these going to fit, or am I S.O.L? My truck is a 2005 GMC Sierra crew cab, 1500, Z71...

Thanks!!!

depends on how do you feel about trimming.

if you want to run those tires without as much rubbing you could either get a body lift or a six inch suspension. with the body lift you'll most likely still have to trim but with the 6 inch you might not have the trim at all if you keep stock rims.

[982500greg]

hey new to this forum but not new to lifting chevy trucks, i used to work at a local shop were i did nothing but lift trucks. but anyways i had a 99 2 dr tahoe, all i did was a 3" body 1" block in the back and jacked up the torsions and was running 35" tires on an 8" wheel without rubbing off road. i did take off the plastic bumper skirt and cut off a little corner of the bumper.http://s175.photobucket.com/albums/w133/fredrickgreg/?action=view&current=randompictures154.jpg

Another 2500HD question...

Is anyone running 295/75's on a 16x8 rim? I just bought a set of BFG AT to mount on my Pro Comp 1079 wheels (4.5 BS) and was wondering if I will need to do any trimming. I currently have the TB's cranked to level. I don't mind a little trim :hack: , but don't want to do anything major. They're running a pretty good deal on 4wheelparts right now. 10% off, free shipping plus $60 instant savings.

A BL is out of the question right now. Waiting for my boys (6 months and 2 years) to get old enough to climb in by themselfs and then going with 6" Pro Comp lift.

[macojoe]

I have a 1500 with cranked Tbars and a 2 inch lift in the rear by adding 2500 springs.

I just added 285/75/16 Toyo's on stock alum wheels, they fit perfect with no triming at all, and there is alot of room, so I would think the a 2500 has a little more room? and you should be ok?

[KidRick]

Sounds good! I'll let you know after they get mounted!

I had to trim quite a bit to get my 285's on, I can't imagine you won't be trimming a lot for 295's.

[KidRick]

Assuming that I will have to trim. Is the only place going to be on the front plastic under the bumper or are there other places that will need to be trimmed as well. Now I'm starting to wonder if I make a mistake ordering 295's??? I still have to imagine they'll fit fine since there are guys on here claiming that they are running 305's on 1500's with no more than a TB crank and trim.

Ok, I've never been the mechanical type, but I'm learning. So I guess my question is, where else will I have to trim besides the front plastic under the bumper?? FYI - my fender height is 41.5" all the way around with 265/75's.

Thanks for any and all suggestions in advance.

[KidRick]

Just took a look under the front wheel wells at full lock. No way am I fitting 295's like it is. Tire order is canceled.

Probably work out for the best. 6" Pro Comp full drop going on with the tax refund. Too bad the wife doesn't know that yet. Anyone know a good shop in the Milwaukee, WI area???

[puck8345]

I have a 05 1500 crew cab and I reseved a set of 315/70/17 off a H2. I may thinking of putting a 3" body lift and using a set of Ford keys. So may question is will I be able to fit those tires or will I have to do alot of trimming

[NDBoost]

Anyone ever put 32x11.50x15 on a set of American Racing 15x10's? Any rubbing on stock height.

[copeland_04]

I've got a 97 K1500 Z71 with a 6" Pro Comp lift and would really like to put some IROKs on it but the smallest size is a 36x13.50. Does anyone know if they would fit, my rim is a 15x10 with 4.5 backspacing?

[chev0626]

i have 315's with 16 in rims on my 96 OBS silverado Z-71. cranked the T-bars about half way and have Rancho RS5000 shocks. also a 3" BL and still have plenty of clearance.

[NDBoost]

Anyone ever put 32x11.50x15 on a set of 15x10" wides's? did you get any rubbing on stock height?
bump anyone?

[CAMOHOE]

for the dually guy look into some 295' nittos or bfg if you absolutly have two about a 33-34 inch tire and on a narrower rim like yours would look a little bigger and proably drive a little better due to less sidwall flex... i have a obs 2000 z71 tahoe 6" procomp and 3" bl running 37/12.50./17, pro com etreme A/T on some black ultra "thunder" 17x8 only slight rubbing in hard turn and bounce and just a little in back under full stuff, but i also have the factory fender flares and that where the rub when the do, average driving no rubbing , stock t-bars and keys for now with them cranked some but not all the way, have some ford keys and 3/4 ton torsion bars but haven tryed them yet to see if i like the ride have good clearence now but like most of us alwasy want a little more, i do have a 5" block and add a leaf in the rear so it sits dead level unloaded but someday will do a shackle flip and new springs along with a custom airbag setup, cuase i do tow with it and any kind of decnet laod and its nose is in the air and tend to wander more

[gibskin]

hey my first time in here, ive gotta 07 4by half ton chevy crew new body, and ive been lookin for a lift. i wanna run the mickey mtz 36x1550r20 with some motto metal wheels, dealers tell me they only make 6 inch lifts and 11 inch lifts for it. is there a 7 inch lift? or maybe a way i can torque up a 6 inch to make em fit, i have no problem with trimming but not into the body lifts

[justforfun]

I just got an '03 Z71 offroad and want to put 33X10.5 on 15X8 rims. Wondering if I'll run into problems with stock height, or if I'll need wheel spacers?

[gibskin]

i had a 97 chev half ton and i had the torsion bars cranked at the tire shop and i fit 33x12.50 tires with a 16x8 aftermarket wheel and had no rubbing issues at all. i dunno how the newer chevys sit compared to the older but its worth a try..leveling kits are pretty cheap. like 200 bucks , you get a couple inches there i think?

[justforfun]

Thanks for the info. Hadn't thought of a leveling kit yet, thanks!

[HeavyT]

Okay It probably has already been covered but I am going to ask anyways. I have a stock '03 1500HD 4x4. I would like to level it and put the larget size tire possible without rub. I do not want to trim. I am not very mechanically inclined so I will be taking it to a shop to get the work done. What do you think would give me the best combination of functionality and look? Eventually I want to run 315's and a 6" suspension lift but that will have to wait until the bdget allows. so for now what do you all think would be best. THanks for the info..

I have a 3" BL with torsion bars cranked and 2" blocks in the rear.
I'm currently running 33 X 12.5 R16 on 10" wide rims. It doesn't rub but it is very close.

Am I going to run into rubbing issues by going to the 13.5" wide tire compared to the 12.5" wide. on the same size rim.

How can I prevent this? Larger or smaller wheel offset?

TIA

i have a 88 scottsdale 4x4, sitting stock on 305/70/r16. with 16x10 centerline offroad racing wheels, and going

to put a 6" suspension lift, and 315/75/r16's under it. what brand do you all think i should get. i've been

looking at the rough country 6" lift.

[bowtieboy42]

Just to check, if I did 3 inch blocks in the rear, ford keys and crank up front, and throw 35's under it, I'd be good to go correct?

[ireckon2237]

I'll be redeploying from Iraq in december, and have plans to get a 2008 silverado,4wd. I have begun doing research on what i want to fix it up. My intent is to lift it, w/ 6" susp lift. appropriate sized BFG A/T's. I'm not familiar with all the brands and specifics. It will be a daily driver, look great but also have what it takes to handle some muddin' on the weekends. i don't expect a full "how to" response, but i could really use some do's and dont's. the last thing I wanna be is "that guy"

Any suggestions about the rims, normal vs offset?

i was advised that the z71 package wd suffice if i don't plan on doing any the "rough stuff".

Yeah, I'm the new guy so feel free to throw all the "new guy" jokes at me.
I've got a million questions, but Ive got another 10 months to put it altogether.
