I wish i would have taken a picture and i may tomorrow . I was at the tire shop there was a gooesneck trailer with two 10,000 pound axles . They had been having tires problems 3 tires all had a flap open up on the side wall about 2 inch square right were the side meets the tread. The flaps started down from the bead to the tread. Some how they never shreaded a tire and they are in good shape other than the hole. What could cause this ?
