While riding yesterday I had a rear tire explode after about 19 miles of riding. I was near my house when it blew so it wasn't too big a deal to get back home. All the neighbors in the area came out to see what happened. I really don't want this to happen again! I was doing about 18 mph and it was scary to get it under control. My question is what tire can I install that will be more reliable than what I had? I had been using a Kenda 26 x2.3. I had 70lbs of pressure when I left on my ride. I can't see any signs of hitting anything. The tire has plenty of tread and has no dry rot I should point out that I am about 270lbs.
