    My truck is completely stock. 98 1500 4x4 HD excab, minimal sagging, my truck only has 74K on it. Looking for some bigger/more aggressive tires for winter/offroading. First off do 15'' wheels work on my truck? ie. clear the calipers.
    Second, whats the biggest tire/wheel combo I can fit? I am willing to crank the tbars. Can I run 33/12.5 on 15x10's??? any input is appreciated, and if anybody is running this type of setup on there obs, please post some pics of it. Thanks!!

    Depends on the truck. Each truck is slightly different due to factory options/wear/mileage, etc.

    Some trucks will rub a 265/75/16 tire while others can run 33"s no problem. They will fit but you may need to crank the t-bars or cut some of the fender/bumper/air dam up to fit them.

    With the right backspacing on the wheels, and a crank, you can get them to fit. May require some minor trimming though.

    thanks for the input guys. How about 15x8 rims w/ 33x10.5s or 32x11.5s??? would these squeeze in?

    My room mate's '92. Stock keys cranked, 2" drop shackle, 35/1250r17 Nitto Trail Grapplers, 17x10 Diamo Carats with 4" of backspacing. The tires just touch the rear of the fender and frame at lock. Dont touch the bumper any more.

    Why the fugg the lowering shackle? Props on the stuffage on the front, but that truck couldn't haul a fart, let alone case of beer in the bed without the tires eating the fender.

    32x11.50 fits easy with 1" crank (stock keys), and I put a 1.5" rear block to keep the rear tires out of the fenders.

    i fit a 33x11.50 on my stock 16" wheels. the inner sidebiters rub the a arm with steering hard over on bumpy terrain, but not to much issue otherwise. i havent touched my torsion bars either cause i figure that it wont help the a arm issue much.

    A crank, 35's, and a drop shackle? WTF?


    Anyway, stock wheels and 33 x 12.50's are doable. The wider wheel you go, or the less backspacing, the more interference you'll run into.

    Here's 32 x 11.50's on 15x8's with stock suspension. Not quite enough backspacing, had to trim the front bumper and air dam to be able to turn full lock. Otherwise no rubbing.

    Quoted for truth, tires and suspension parts will wear at warp speed and just cuz you asked for pictures this is what not to do:
    315's on 16X10 only bars maxxed.
