Hello to all, just wondering why the inner part of my rear tires are going so fast versus the middle and outer part? I know the way the suspension is and the tires sit some what in an angle. But is this really normal? Or do I need some sort of an adjustment? Please advise. My tires are Perelli assimentricos and I have probably maybe almost 20k on them. I have an 01 4.4 X5, Sport package. I'm going to have to buy a new rear pair in a few months. Not only that, the driver side rear tire is worn a little more then the passenger side rear. Hope someone can help me and shed some light my way. If this is normal then OK, but if this is not, I need to fix this asap. Thanks in advance.
