I bought a 2008 xB a few months ago from a dealership. The carfax showed left rear damage, but it looked like it was repaired right and it was a decent price. At the time, I noticed that the rear tires had just been replace; but didn't think much of it. Well recently it started hopping in the rear, like I had a tire out of round or something. The first time I looked, the tires still looked new. It wasn't until I looked under the car that I saw that the right rear tire is almost down to the cords, but only on the inside 1 1/2" or so. PLEASE< ANY ADVICE OR IDEAS?
