This may cause some rubbing if mounted on a lowered car and require spacers to correct. I went with 275-35s to play it safe.

One other thing I ran into is that a couple of tire shops refused to mount tires that were 3 sizes over OEM. Something about liabilty blah, blah, blah. These were usually the franchise stores, but I found a Mom & Pop place that didn't know the difference.
