Alright so this tire hung on a hook in the garage for awhile when I put Conti GP 4 Seasons tires on in early 2014. When the rear GP4S wore out, I put one of the original Zaffiro tires back on, because I'm cheap. Then that one wore out (several patches of cord showing), so I swapped that out for the tire shown in the first post of this thread, just about 3 weeks ago. I guess the Shoe Goo fix must have worn out and come off or something. I had the bike in the stand, spinning the rear wheel and suddenly *PSSSHHHHHHH* the tire ruptured at that spot, the tube sprung a leak and broke through the cords at that cut in the rubber.

Glad it didn't happen on my commute home from work yesterday.

So that's 3 rear tires in 7,200 miles. Taking the bike on a trip tomorrow so I have to make an emergency LBS run to get a 25c tire.
