Wow. That's a 65k tire??? Impressive. Looks like a piece of a piston ringSucks.
Well, I do a 5-tire rotation so I guess that's cheating somewhat haha! I have been happy with the wear of these though!
I was hoping to get 75k out of the set but that looks to be cut short due to this finding. Not worth putting 1 new tire in the rotation or shaving down a new tire to match.
