I have 2 words for all that are troubled with frequent flats...TIRE LINERS! I started using tire liners on the suggestion of my riding buddy, and it's been the best advice I've heeded so far. Sure they won't prevent every flat from happening, but I am convinced that having them in my tires has prevented quite a few. I've picked out tons of glass and sharp debris from my tires, that would have likely caused a flat had it not been for the tire liners.
