I had this tire since about early November. I have had MANY flats, and leaks with this tire.
As of right now, my tire is dead. Completely ripped on the inside where the kevlar bead things are showing.
This caused me to get a sidewall flat, which ruined my week at my Grandparents house because I couldn't ride the nice spots around there.
There is also wear on the sidewall. This tire also has very little grip, I slipped on ramps every now in then.
I also heard from a friend that this tire messed up his manuals, but I think he has them back now.
Overall this tire gets a 5/10 because its REALLY light.
