Just recently on a short trip with the RV I had a tire that lost of its tread, not by simply flying off but wearing off. The real baffling part of this is that it was one of the duals, the inside on. The outside tire appears OK except it is showing more wear than the tires on the other side. One possibility is that I lost about a foot of my tail pipe but the remainder is not blowing directly on the tires. Any experience hear. I think tire was just defective. Dieslman
