I recently got my first set of Gatorskins, some 25s, for my weekend road bike. I had four flats in the first couple of rides. In my case, the problem was due to user error, pinching the tubes on the tire beads. The beads were extremely stiff on the Gatorskins and they were very hard to mount even with tire tools. I have had a lot of experience mounting tires and these were the hardest tires to mount in many years of cycling. I finally took my bike to the LBS and got them to mount the Gatorskins and they have been trouble free since then. I just hope I don't get any flats because I am not convinced I can change the tube without pinch-flatting it. I put some Vittoria Rubino Pro 25s on another bike about the same time, and I love these tires. They are lighter than the Gators, roll nicer, are much easier to mount, less expensive and reportedly very durable.
