On my '67, I run 215/65R15 on the front and 235/60R15 in the back, but they rub. The fronts rub when I go towards full lock and the rears rub whenever I hit a sizeable pothole. The fronts also have a tendency to grab the chrome around my front wheelwells if I hit a bump while I'm turning (like going into a driveway). That being said, I believe my car has been lowered a tad. Not sure if it's just old springs or the PO did it on purpose. Could also be a backspacing problem. I like the look though. Everything tucks up underneath the fender wells. I can live with the occasional rub. I just have to be careful about it.
