Tyre Cuts… How much is too much?

    Righty…

    After diligently picking out all the wee bits of glass from my tyres after the weekend’s riding, I notice that on the rear there is a 1cm long gash horizontally across the tyre… After a bit of poking there doesn’t seem to be any glass left in it but I can see what I assume is kevlar fibers and it gapes about 1mm wide.

    Am I being anal or is this tyre dead now?

    :/

    If any component on the bike inspires less than 100% confidence it must be time to replace it. I imagine Peter Sagan might be a little more cautious next time he enters a final corner. Not sure if he’s out today – wonder if he’ll be on clinchers though 😕

    I had a deep cut in a new Schwalbe Kojak tyre, though not quite through to the carcass. I deflated the tyre, cleaned the cut with water, dried it, then glued it together with superglue. It seemed to work well, so I rode it that day. A few days later, checking the tyre to see how the repaired cut was holding up, I couldn’t find it!

    I do the super glue thing all the time on cuts, as long as they’re not right through to the carcass. They never re-open.

    haha… actually considered that but I’m not sure I want it lurking at the back of my mind on a descent-I need ever grain of confidence I can muster! I’ve already put a spare cheap but decent vittoria on-with the state of the roads it seems a bit pointless putting anything better to task anyway. Maybe I’ll try it and put it on my commuter instead.

    I’m pretty sure it’s from cycling along one of Boris’s ‘Superhighways’ on the way home on Saturday-so much broken glass on them following weekend revellers throwing bottles and glasses about it is impossible to avoid. 🙁

    cheers for the input chaps.

    I’ve used super glue to pretty good effect (both on standard clinchers, and on a split in a tubeless tyre that had been sealed with latex sealant but had originally gone all the way through). I’ve saved a fair bit of money on replacement tyres this way, when there’s plenty of tread left but a split would have written them off, so I reckon it’s worth a try if the tyre is quite new and is expensive to replace. Deflate the tyre, a few drops of superglue in the split, then hold it together until it seals (being careful not to glue yourself to it, like I did the first time #o ). Leave it a while and then test it on a short route to see if it holds. If not, all you’ve lost is a few drops of glue (and maybe some skin).

    Dead. If it’s big enough to potentially allow the tube to be exposed or push into the gap then it is time to chuck.

    Some people have been known to use super glue just to close the gap at the bottom.

    Never tried it myself… depends how you feel about it

    Oh well-lucky it didn’t blow on the ride and send me shooting into some bushes. Got a spare vittoria zaffiro kicking about somewhere I think anyway.

    if you can see the weave of the casing under the rubber i’d say you’re better off replacing it.
