  1. As long as you’ve removed any piece of glass, if you change the tube or patch the tube you shouldn’t need to change the tyre.
    Both are fairly easy things to do, just watch a video from YouTube

    Can you put your finger through that slice or is it just superficial? If it’s just superficial it’s probably fine. I don’t know what to do if it’s cut all the way through, though. I have a tire that I cut the same way at around the same mileage and also want to know what to do with it. Seems too sad to get rid of a such nice, crisp tire over a slice 😭

    You’re good, man. If it’s big, you can put a piece of cardstock (like an actual piece of a playing card) between the tube and tire. That helps the tube not be compromised by that slash. It works like a charm for those kind of punctures.

    If you wanted to be sure of it not splitting more on you, you can place a strip of an old tire on the inside of the tire where the slit is. For my road bikes I keep old tire strips in my saddle bag for emergencies like this.

  5. Unless you keep getting tube punctures in that same spot, I wouldn’t bother replacing it.

    The cuts I’ve had that are problematic are the ones where you can see inner layers of the tire without prying the slit apart or ones that push a piece of the belt into the interior that I can’t smooth out.

    Always make sure you get the debris out of the cut.

  6. Nah, you’re good. See if there’s any glass or metal stuck in there, make sure nothing is inside and put a new tube in if it’s flat.
