I'm getting ready to replace tires on my GT/SC with factory 18"x8.5" rims.  Stock tires are 235/50/ZR18 and I would like to try to increase to 255/50/ZR18.  Has anyone been successful with this size without any tire rub?

I have 295's on 10" deep-dish bullitts, no rub. I know of others with 305's but that's pushing it on a 10" and they poke a little beyond the well opening. Traction can be problem on an SC, hence the even wider tires (that still cut loose).

I believe 255's fit an 8.5" wheel, but that's it.

Also tire width/traction depends on what type of SC you have. A paxton kicks in at higher rev's (less initial wheel spin) whereas a KB or Whipple is immediate.

Welcome to the "does it ever end" paradox. Add more power and other things need to be changed for better performance.
