bias, 04 new 1200x20 ndt, in this case I had H rated tires, because of the front end WEIGHT, I should have had Js there, I was so thrilled to find new 1200s, didn't think about the weight rating. not sure if that was the cause of the event or not, but DID NOT HELP, when I put my kand on the tires, thay were hot to the touch. WILL NOT put ndts on the front again, found some 22.5s, a heavy J rated that will go on before any trips. I can live with a wrecked wrecker, would be hard to do if someone got killed or badly hurt because I FAILED to check the weight rating. HAD the 819 to the first GA. rally on these tires, ran hard on them to/from as well as other places, no problem
