A quick question while we're on the topic of Hoosier. I just upped my wheel and tire set up to 18x10 with 285 ad08's. Assuming I can fit the 285 ad08's comfortably under my fender and quarter panels, should I go with 265 or 275 r7's?

Edit: I meant 275 or 285 r7's

My situation isn't for TTC, it's for GTA SLB & vtec club. I was just inquiring about tire fitments.

Sorry, should've specified.

rc1 wear like iron, and have an awesome contingency. they will never hold a candle to a hoosier though. hoosiers are great for 1st 4-5 heat cycles then they start to drop off. after 30 i render them useless and a fresh set of rc1s might be able to keep up
I've done 9 weekends on my RC1s and they're still not even at the wearbars. 4-5 mph faster per turn @ VIR over my RA1s. Absolutely fantastic tires. Taking next year off as got a kiddo on the way, but hopefully can get the car ready for TT4 by the time to start back up.

Tire Rack has a great database of tire widths. I'd check there but there is a noticeable size difference between a 275 and 285 which is why NASA has a modifier change when you go from 275 to 285.
