i tell you if it wasnt for bad luck....i just put on power pilots 500 miles ago. it was beautiful today so i figure i would go on 1 last ride before storing for the winter. i get about an hour away and my tire goes flat fast. noticed it while stopped at a light. pull over then there is a razor in the tire. put about a 1 inch gash in it. i was able to plug it and linp home. there goes 180 beans.
