    Tire puncture a problem? Tube is fine.

    Hey all,

    I managed to get a nice flat over the weekend when I tired bunny hopping a mud patch and my rear tire landed on a small knife-edge of a rock that I didn't see. It punctured the tube and tire, and I was able to get a spare tube to fix it up, and ride on for the day.

    My question now is, should I do anything to try and fix the tire? Any type of patch I should put on the inside surface? Duct tape? Thanks!

    Are the tire punctures big enough to let sand and stuff get on the inside?

    Some holes in tires may be fixed with glue.

    How big was the tire puncture? If you were able to put a new tube in a ride away, seems like it was a small puncture and shouldn't be a problem. You can superglue any small holes to help the tire held together in the long run.

    Now if it was a big puncture, the kind you have to put a tire boot inside to keep the tube from coming through, you need to replace the tire as tire boots are just meant for temporary use.

    The tire puncture is a bit less than a centimeter wide slit, basically. I was able to ride another 2 miles without any tube problems, so I'm leaning towards just plugging it up with glue to avoid any sand and particulates getting in.

    The glue may do it OK if it is in an area where the glue has some surface to stick to.

    I've only had slits in tire sidewalls (from sharp rocks...) and they deteriorate into bulges that let the tube peek out. Not good.

    Shoe Goo works pretty good for stuff like that.
    If you cut some cords in the tire carcass however, it weakens that whole section of the tire and it could blow out later. A tube patch on the inside of the tire might be a good idea to distribute the force in that area.

    Tube patches stretch a lot, just like tubes. If you want to put a patch there, use something more rigid.

    You can put a boot over the cut inside the tire (Park makes some), but you're asking for trouble riding it like that.

    My attempts with tube patches and pieces of tube did not work, so I deemed those tyres a loss. I don't have any specific products in mind but what I tried did not do me any good. I guess duct tape does not stretch much but it might leave abrasive areas against the tube...
