Like the idea of the same tire size at all four corners for the upcoming fun season. What size 18s (better tire choices) are the C6 owners using with no fender rubbing? Searches returned quite a bit on the C5s and the 18x9.5 seems popular with a 275 tire size. What's the offset being used?

Ideally, I like to use a 285 or 305 at all four corners which mean an 18x10.5 but am concerned with rubbing.

I have 18x11 CCW Corsairs on all four corners of my C6. 295/30r18 front, 305/35r18 rear. _Minor_ rubbing on the fender on the front. Note the backspacing is WAY different front and rear, so if you wanted to do 295s all around you'd need a good size spacer.

Call John@CCW and I'm sure he'll set you up...

CCW 18x11's with 315's all around. If I had it to do over, I would have went with a 12 out back and a 335. I have some rub issues but they are related to the inside fender wheels at full lock and the inner part of the fender. Nobody other than yourself will ever see it.

Your size is going to depend on what your trying to do with the car, if your trying to be nationally competitive, anything smaller than a 315 isn't going to cut it IMO. The rubbing will also depend on your setup, shocks, camber, etc. This also pertains to AutoX and the ASP class.

Thanks for the responses. I'll give John a call
