Can someone give me a real reason on why big wheels = slower times.

I"m looking to put 19x8.5 and 19x9.5 evo's on my car what differences can I expect....

I currently have stock 16's

Will my handling increase or decrease

with I obtain more road noise?

what about my times?

When comparing my current wheels against my new wheels with the same brand of tires which ones will get better traction? The new ones are wider will that help?

basically what are the pros and cons.

The wider and lower profile tires will help cornering but will hurt the ride and can be succeptable to rim damage on large pot holes. Depending on tire design you may hear more road noise. It also depends on the condition of the roads you drive on. The wheels will weigh more than the stockers and cause more unsprung weight affecting handling and drag strip performance. Wider tires have a better chance of gripping on uneven surfaces but if you have a smaller rim and taller tire it increases your bite at the drag strip. Pick up the latest issue of GM High Tech Performance for a good tech article on drag racing and wheel and tire choice.

I got mine weeks ago. He is right about the wheels, although mine don't SEEM to have slowed me down. I'll got some 15" slicks and skinnies one day, when I get real serious. And keep the 18's for the street.

Got my GMHTP Oct 05 issue a few weeks ago. Did you forget to renew your subscription? LOL

What reasons do you consider not to be real?

19's are just too big in my book on the F Body. On the 16's my car rides nice, but on 19's I'd think it would feel every little bump. If I lived in a area that had great roads then it may be ok, but with the roads here there is no way. Also on looks, I seen some T/A's that looked great with the Evo's in 19, but I seen some others that the wheel looked too big. Seen a guy in a parking lot one day with what looked like 19's or 20's on his Camaro(was a 98-02 v6) and the car looked like it was 4 wheel drive. The 19's are heavy and extra weight and rotating mass = slower. How much, I have no idea. Did you check the weight if those wheels yet?

Yeah pretty much what he said. Even if the 18s or 19s are somehow lighter than 16s, they would still yield a slower time due to bigger rotating mass.

a bigger rim in the back will make your gear ratio less aggressive also.

The last two posts are very incorrect.

Allergik2dyin.......mass = weight.........the less weight you have, the less rotating mass you have, no matter the size of the wheel.

CamdLs1.........A bigger rim will not change the gear ratio as long as the Overall Diameter of the TIRE has not changed

245/50-16 is 25.6 tall
275/40-17 is 25.6 tall
275/30-19 is 25.6 tall



The lower the profile you go, the less sidewall you have to "wrinkle" or give when you take off......thus the more wheel spin you are gonna get taking off. My 295/30zr18 Pirelli's on chrome 18x10.5 Z06 wheels spun worse than my stock 16's with 245/50zr16's no matter the road conditions. They had no give.


If your wheel weight and your overall TIRE diameter is the same then if your car will hook it should be equally as fast as it was.

Dude this post should be made a sticky!! Those two last posts before you are two of the biggest myths about wheels. You work in the mythbusters???

They don't even help with cornering. As in drag racing, not enough side wall allows the contact patch to "peel up" too easy. The best wheel size for making an fbody handle is 16" diameter rim about 12 inches wide. Large wheel diameters on an fbody are all cons and no pros, unless you just like them for looks.
