I'm mainly intersted becuase there are a couple decent offers on EBay for 18x9 rims with 275/35/18's. I'm currently running 225/60/15's(bleh) and when wheel locked up front there isn't much room to spare. I figured they'd rub for sure with that size with out a little extra work.
im not sure, i know on the 15s the factory size is a 205/65/15, and you have a 225/60 wich is..pretty close to same diameter, the 275/35s are about 3 millimeters taller than what come on Sallens....wow. but im sure as long as the wheels are the right offset there shouldn't be a real problem
