I've been running 225/45R15 on 7" and 8" wheels and they worked fine. But now that I need new tires I'm going to 8s all the way around and debating about stepping up to 245/40R15. Anyone have experience with 245 on 8" wheel? It's within spec from Hoosier for that tire and through email correspondence with Hoosier they said it would work fine. I also asked them about building heat in the tire since I struggle with that on the 225s already. They said that yeah I would build less heat but the cooler 245s would generate more grip than slightly warmer 225s.

Depends on the car, flares, and wheel offset.
I run 245/40-17 on 8" wheels up front and 225/45-17 on 7" wheels in back -- but this is on a 2500# Honda Civic Si Super Touring car. What were the temps with your 225? How well did they fit your car? From the info you've given us, then I can assure you that 245s will fit on an 8" wheel just fine. But will it work on your wheels on, your car, in your application, at your tracks? Testing, tuning, and tire temps is your friend. First step: have the tire busters at the track save a 245 pull-off for you, have them mount it, then you check the fit on your car. Go from there. BTW, I run 205 Nittos on 15x7 Panasports on my 914 historics car. Barely fit inside a "massaged" narrow-body car. 205/50-15 Hoosiers rub, 'causes there's a distinct difference between "205 millimeters" and "205 Hoosiers". |
