My guess would be 335's.

This needs at least an 11.5" or more likely 12" wheel, for a proper fit. I don't see a 12" wheel running without some tub work. I run 315's on 11" wheels and pretty well maxed out. Many will run a 335 on a 10" or 10.5" wheel and is a complete waste of such a tire and a poor fit as well

Agreed with everything (including what I edited out for space reasons).

Says 335/30/18 on a 10.5" rear rim in his sig.

Agreed again.
At that point, on a street car it's all for looking fast and not real performance. My 295 KDWs are all the tire my car will ever need in the back. I've yet to run into a street car that needed more than that for traction.
