View Full Version : 20s that bad in the 1/4
12-10-2004, 10:48 AM
one of my friends was at the track last night with his scsb 5.3. His first one was a 15.8 cuz he was spinning a lot, but that was with his 20s. Than switched out his rear tires to the stockers and he hit a 16. We went back and fowarth and with 20s hes in the high 15s, without them hes in the 16s. Im thinking about putting 20s on my new truck...but will the same thing happen. This truck again is going to be ext cab in the performance area. Will 20s really hurt it that bad?

The proof is in what you posted... People say its more unsprung weight and its evil blah blah. But the clock doesnt lie.

Depends on what size tires, since it essentially regears the truck for you.

I'm not sure what you're asking. He's faster with the 20's on the truck as you noted so what is going to get hurt? Now, don't expect a faster time just because something has 20's...has to do with rotational weight, the weight of the wheels, and the tires....
16's with stockers and high 15's with 20s.

all of them are going to make a difference but some less than others. if your lookin to keep them light go with a good billet wheel.

I bet he has light weight 20's and they have more traction because they are wider or have a better tire

I called him up to see what they were, they are chrome 20x9.5 now im thinking of getting sumtin similar but in billet *since they are lighter*. Do you guys recomend going with 20x9.5 all around, or something like 20x8.5 on the front and 20x9.5 or is that just for looks?

9.5 in the front sticks out doesnt it?

8.5s up front and 10s out back....no need for a big meat up front

Appearance is subjective. Your money, your ride. Spend it as you wish. However, performance is objective. Overall diameter and mass of the wheel will affect the performance in handling and acceleration. For acceleration, you want small overall diameter (for buzzing the engine to redline quicker) and the least mass. However, small diameter gives it small contact surface. For handling, you want the least side wall height. Why not invest in a set of cheap steel wheels with good slicks for the track?
