My high pressure set, fell apart. Sidewalls not strong. Outer rubber is glued on, and seperated.
I bought a set, to try high pressure on a 26 inch bike, with 1.5 width tires. On one, I did not notice, the bike was rubbing on the sidewall slightly. In a short time, easily weakened the sidewall, and a the inner tube bubbled. On the other one, after a flat, I looked to see, the construction of the tire. In two places on the tire, the outer hard rubber, completely seperated from the innner softer rubber, revealing the small layer for puncture resist. Reminds me of retreaded truck tires, which you see on the side of the road. Neither tire had very much wear. Never had a tire, that fell apart, this easily. Until they fell apart, I liked the tires. Lighter weight, may not be worth it, if the sidewalls are so feeble, and the outer harder layer of rubber, is only glued on. I have not had a car for near two decades now. I cannot trade of, lighter tires, for utility. Up to the time I bought this set, I always bought lower cost tires, and never had such construction problems. These did not lost long for me. I cannot believe, that the outer rubber disconnected in two seperate locations of the tire, with so little use. I can stick my finger between the two layers, and see, the puncture layer. Perhaps I purchased two lemons. But why should I pay more for less. If yours works better, good for you. But for me, I depend on bicycles for my transportation year round. I cannot afford, to have tires, that fall apart so easily. I blame myself, for the sidewall rubbed by the brake. But the outer layer of rubber, should not be so easily seperated. bikes are my primary means of transportation. Based on my experience, not a good choice for me.
Thank you for your feedback.
