I have 2013 model year Jayco Eagle 304 BHS with Carlisle Radial Trail RH ST225/75 R15 117N Load Range E tires. I upgraded the tires from original Load Range D to E. Just the rear tire on the driver side has abnormal wear. The wear is excessive compared to the other 3 especially on the inside. All the other tires are wearing evenly. I had the same issue with the last set of tires. Is my axle bent? If so, how do you fix it and how much will it cost?
