Autocrossing if I'm not mistaken, the STX class allows for 9" wide wheels and most people are running 245's (some 255's). From what I've heard it's hard to get the 255 and up in the operating temperature and it's known that the larger tires can result in slower track laptimes due to weight, rolling resistance, and diameter changing the effective gearing but autocross focuses on mechanical grip and the gearing can eliminate a shift or prevent you from hitting the revlimiter on the straight.
Sounds like the 8" would be more appropriate for you (and you can still run the 235's) as you're not competing and sticking with stock power more grip from wider tires isn't terribly necessary, not to mention the 8's will be lighter which is a noticeable performance advantage.
Hey Sharky, I'll be ready to trade mine in about 3-5 years after I'm done being competitive :bellyroll: |
