Small cut in sidewall.

Hi.

Just wondering if it's still safe to use the tyre, it has a small cut in the sidewall, it only just about goes through to the inside of the tyre as a little hole so wondering if it's safe to use still?

Probably half to three quarters of a centimeter on the outside and just noticeable on the inside, it's not a clean cut.

    Chances are you'll be fine. Keep an eye on it and if it changes at all - time to say goodbye. If you are going to keep it, I'd probably think about having it as a rear rather than a front.

    However, some of advice must depend on what riding you are doing. If you live in the pennines for example and are doing some serious speed descents, the thought of a high speed deflation isn't worth saving £20 on a new tyre.

    Another thing to consider is patching the inside of the tyre - not to make it more puncture proof, but simply to eliminate the possibility of suffering a 'hernia'. Some thick gaffer tape would probably do the trick. I've tried with inner tube patches but they don't like sticking to the inside of most cycle tyres.

    I've had success with a bit of old tyre cut out and superglued over the inside of the hole.

    It can lead to a bulge in the tyre which may not be noticable as you ride; my mkII patch was ground thinner with a bench grinder to take off excess rubber. Seems to work just fine.

    You'll want to put something in there to support the tube in case the tyre carcass continues to unravel, e.g. toothpaste tube is a common ghetto fix. Keep an eye on it when it's pumped up, if it gives the tube will start to poke through.

    As well as patching the tyre I would move it to the rear and have an uncut tyre at the front so that if the repair was to blow you would have greater control.
