So I was riding home from crit practice tonight and noticed that there was a bit of a hop in my wheel. I checked it when I got home and found this:
Looks like the rubber on the outside of the tire, and the first layer of the threads tore. I assume the tire is done, as it has quite a few miles on it anyway. Just wondering what would cause something like this and if there's any way to avoid it on my next set of tires.
