My X is not pulling to either side but I am noticing unusual wear. The F/L is wearing on the inside outer edge and the F/R is wearing on the outside outer edge. If the tire is under infated you can get wear on both outer edges with the center tread being fine. Never seen this kind of wear before. It appears the wear is at least 70% of the tread. I need to get the alignment checked and tires rotated ASAP, will post results.
