I've used 4 different types of tires on my road bike now. My rides are everything from commuting every day to double centuries. In my opinion the Gator Skins are where it's at. In about 1000 miles, the only flat that i've had was because a shard of metal punctured one of the tires which would have punctured a sheet of steel. The roads I ride are pretty rough and I'm very happy with them.
