I hit a little piece of debris on my ride home tonight that was as sharp as a razor. It made a clean slice in a nearly new puncture-resistant tire about a centimeter wide. I carry a folding spare so I just rode my spare tire home. Is this something that can be permanently repaired with a boot or something?
I don't want to throw out the tire if it's repairable but at the same time, I don't want to flat constantly because I'm too cheap to buy a new one.
