    Got my first flat on continental grand prix tyres tonight.. There's about 500miles on the them. The cut looks bad enough. I attached some pics. Would appreciate some opinions on them.

    The last pic is what the tyre looks like with a new tube pumped to 110-120psi

    Plenty of life left in that tyre.

    Was worried the inner tube might bulge through the slit when it rolls over that point of the tyre

    Doesn't look that bad to me. If ur worried put that tyre on the rear wheel. Better to get a pincture on the rear wheel than the front one.

    Look on the inside. If the hole goes all the way through that's bad.

    This.. And if the inside wall isn't damaged then (when the tyre is deflated) drop some puncture glue into the cut and allow to dry before inflating the tyre again, that usually helps close the slit.

    And stick a patch on the inside of the tyre too just to be sure (and fit the tyre on the rear)

    A few people have mentioned sticking the tyre on the back, is this to prevent me going over the top as it will be more prone to a blow out or something different? I thought with the weight on the back tyre this would not be a good idea?

    Actually can anyone recommend a tyre sealant glue?

    The front wheel determines direction. If the tyre blows and you loose the ability to steer then you might be in trouble.

    Not to mention that the force of the blowout might throw you off course in and of itself. One's arse being over a blowout tends to dampen the effect of that, due the added weight. This is also before considering that the use of the front wheel to steer also means that it inherently has freedom to pivot, which is bad in a blowout.

    This is useful. I had to bin a tyre with a bigger cut than this because the inner edges of the cut were chafing the tube and puncturing every 40k or so. Patching the inside of the tyre kept the replacement at bay for a while.

    New wheels is your only man, if that doesn't work then new bike should sort it..
