Tire Tread/belt problems of the 2013 Ford Escape

235/55 r-17 99t this is one of a set of two tires I purchased in oct. 2021. The passenger side front tire had the same issue discovered a few weeks earlier. The steering wheel started to shake while driving. I took the vehicle to the shop who informed me the tread was separating like the passenger tire was separating a few weeks earlier. Again the tire was more worn on the inside versus the outside tread. The replace tire indicator was still in place. It seems very odd that both tires purchased and installed at the same time had the same issue with the tread separating. I have both tires in my garage if anyone wants to inspect them.

Tire 235/55 r-17 99 t. The steering wheel started to shimmy while driving. I took the vehicle into the service shop found that the a section of the tire was indented and the inside of the tire had a bubble. The repair shop stated this was caused by the tread separating. The tire had to be replaced. The tire is 2. 5 years old and the tread on the inside was heavily worn while the outside tread was in good shape. The replace tire indicator was still intact. I purchased this tire at the same time I purchased the driver side tire.
