Hi,
I have Dunslop Sport A2 tires on my bmw 318i. The rear passenger side one looks rather odd. Although inflated to about 2psi over its suggested pressure, the center of the tire looks as if it is cupped continuously around, so that the outside tread contacts the ground while the center does not. Of course under weight it contacts fine, but when off the car, I can easily see it. However, additionally, this tire is wearing more than the others. Despite this 'cupping' pattern, the center of the tire is actually worn more than the outside lugs, and worn more than the center treads on the other three tires. I do have slightly higher presure, but that has only been for the past few weeks, before that I had it exactly per spec. Any information on why this may be so, or how to fix these problems would be great. Do some tires just go bad like this? Thanks,
JMH
