OUCH, yea ive seen it before when cars' mallcrawlers with those ultra low profile tires hit something like a BIG pothole, the dont have enough tire to absorb the shock so the wheel itself is forced to
even on a sports car i would never run anytrhing less than a 50
my Celica i had 225-50-14's on the back and 215-50-14's on the front
although for the price, 225-60-14's would be a more logical choice
