Walls on tire feel thick.Really niceI've been rebuilding an older mountain bike and the new tires have just set it off.When my old tire tore I did not have money to go to a bike store and have it fixed so I turned to Amazon and found this product to put on myself. I was skeptical ordering based on the price I didn't know what to expect for quality, however, after using this tire for several months I would highly recommend. Its good quality and has good tread.Great quality and fit perfectly.I bought a used bike for my wife, and did some upgrades right away. If you just need a replacement tire, these are perfect. No bells and whistles, just a good looking, good quality, mountain bike tire. Would order again if the need arises, or recommend to anyone!Ok tireI used Youtube to talk me through how to install a tire and it all went according to plan. Good buy. Would buy again. This was for my daughter's mountain bike that she inexplicably corded the rear tire on. Not sure what she was doing but this was easy enough to fix/replace.
