widest tire for a 17 x 10.5

i have seen 335s, dont waste your money, get a 315 nitto drag radial and enjoy traction

the nittos also kill alot of my understeer in the turns and prevent snap oversteer, if handling is you game
 
I run 315's on mine..had fender flares and they rubbed the tires when I went around corners, took them off and haven't really had a problem since. The tricky thing really is finding the tire you want in that size. I'll probably drop down to 295's or 275s next time. The wide is cool in theory but I don't think the extra 20-40 mm add as much to the look of the SN95 as they do on lower-flatter cars...
