My right rear tire wares from the inside to the middle only the rest of the tire is good. I’ve had two blowouts because I can’t see that part of my tire without getting down on the ground to look at it. The part I see looks good. My tire seems to be kicked out a bit at the bottom. This is the only tire I have problems with.
