Biggest Competition Tires on Stock FD wheels (on FD?)
 

Howdy. Currently running V710 245/45/16 on stock wheels on the FD. Looking to step up to V700 or Hoosier slicks, but it looks like rims might handle more?

Look on Kumho or Hoosiers website, or Tirerack and look at the suggestest wheel width range for whatever tires you want, and it will tell you what size you need. Just because you can possibly get a 275 on a 8" wheel doesn't mean it will handle better than a 245, which is really about as wide as you want to go IMO.

I have seen the 265/45/16 710s fit without any issues.
