Help! My friend has a 95 SHO with 18x8.5" alba rims with sumotumo 225/40zr18 tires. They all have a slight feather on the inside edge, which I understand is from too much negative camber?? but the problem is the front passenger side tire. the inside edge looks like its been gouged out! Instead of being rounded over like normal, it actualey curves in. now what really worries me is that it only does this 3/4 of the way around the tire. His wheel bearing seems a little loose, could that be the problem?? or could it simply be alignment or a bent strut or something???
