I had a USED set of 36x14.5r15 and three out of the four were ¼" out of round. They had good tread depth and worked well with what little offoradingI got to do with them. When I attempted to get them balanced and the front end aligned, the guy said one was coming apart. I decided to sell them and get something else because I could see my windsheild frame moving from side to side when I was looking at the road ahead of me. Couple months later the guy I sold them to was trying to sell three....the other came apart. I felt bad for the guy but I was honest with their condition at time of sale. Everything I had heard about them was good, that's why I bought them. Again, this was a USED set.
