This for my 01 MDX. Tires are BFG Long Trail T/A and have about 25k on them and have been rotated and maintained properly. While I was conducting the pre winter tire tread check I noticed that just the center tread on the rear tire showed quite a bit more wear as compared to the front. There are no other abnormal wear patterns and the overall wear between the front and rear is similar, just this center tread on both the rear tires is wearing more. No alignment issues either. What could be the cause for this ? Why would this happen ? Pic below is not the actual tire on the vehicle, but it is a BFG LT T/A just to show you the tread band that is right in the center. Thats the center tread I am talking about.
