Ok a while back ,I bought several of the Kenda 26 x 2.125 flames on their weekly special $4. I had one aired up on a rim for a while. When I looked at it and noticed it had a big (baseball size ) cancer on the side wall. I stuck another one one there . I'm watching it too. So if you have some of these watch them or you could be walking home from somewhere. I don't know if this was a once in a lifetime event or if they have a sidewall flaw/weakness involved. Just watch them. :shock: :shock:
