Just wanted to say that Mr. Tuffy saved my ride yesterday. After I rode home from work, I inspected my tires as I usually try to do after a ride. The front tire had a chunk o' glass sticking out squarely across the middle of the tread. It must have been a half-inch wide. When I pulled it out, there was a gaping hole left behind. I pulled the tire off and declared it dead. The glass had gone all the way through the casing, which is no mean feat on a Continental Sport 1000 (lots of tread). The Mr. Tuffy strip underneath was also gashed, but only about halfway through. Without it, I would have had at least a flat and possibly a blowout. This was a close call that could have ruined my perfect record of not flatting a tire with a Mr. Tuffy strip installed. Did I mention that I hate flats?
