My car's ready for new tires and I'm wanting to go with something a bit larger than my 245/45-17's. They're nearly an inch shorter overall than the stock tire. I'm considering a 255/45-17, which is in between stock and what I have now. I'm also thinking of going up the next size (255/50-17), but they are taller by half an inch over stock and I'm worried about rubbing. The car's lowered with SSC springs, BTW.
