So I was finally able to make it to the garage and get the tire off today. A few observations:
- since pumping the tire to 105 PSI over three days ago, the tire is still firm, with no noticeable bulging
- taking the tire off the wheel, I can see that the tread was cut all the way down to the threads (see pic), but
- flipping the tire inside out, there doesn’t appear to be any visible damage to the threads from the inside (see other pic)
Given that the tire seems structurally ok at the moment, I reinforced it from the inside with a Specialized glueless patch and put it back on the wheel.
I figure I’ll keep her to shallower, less technical routes for now to reduce failure risk, and leave the heroic climbing and glorious descending to the Lynskey. As I’ve called out in my other thread, this bike is due to get new wheels soon anyway (Zondas or Ksyrium S? Chime in on the other thread!). Once the new wheels come in, I’ll re-evaluate. If the newer, wider rims can fit the 28mm backup tire, then maybe this one gets retired, or demoted to backup duty.
