...... UPDATE. As a result of this thread, I just examined the tire again very closely. We have driven about 320 miles since I first noted the wear. Now the “sharp groove” pattern has rounded a bit with no other wear issues on the tire. One more telling thing that should narrow it down a bit, is that today I also examined the left front tire and found the same wear just starting on BOTH the inside and outside of that tire. Same width 1/2” or so but not nearly as deep. Running my fingers over it maybe the new is 1/16 or less
Sorry I did not check all of this today before posting. I wanted the manufacturers recommendation before Monday at the shop and was blown away by three completely different numbers. Monday should tell the story at the shop. Will advise..
Still sounds like a belt separating. That photo would be very helpful to sort this out.
Oh and those tire load charts? They are MINIMUMS!! If you are getting wear on both shoulders, it just might be that the tires are under inflated.
