While I was changing the rear to the front so I can "make do" until next week when I can get new tires, I noticed the sidewall on the front tire is cracked and has separated so that I can see whatever layer is red within these tires. I can say that I won't be purchasing these tires ever again. A puncture, my fault no biggie. A sidewall close to failure after 500 miles at 115 psi.... it doesn't inspire much confidence in the brand.
