Well that certainly was a bummer. Maybe I'm just lucky but these are the best tires I have ever run. You can see in the pictures I provided on the reverenced thread that the rear tire did indeed wear out. Now at 8,000 miles on the front tire I am noticing a couple of cracks in the tread but as of yet no damage. Will update the thread when I change it out. So far it has lasted longer than the frame!
