Repairing a tubeless tyre

Managed to get a puncture at 97 miles on the velo Birmingham at the weekend with a nice hole that won't hold pressure. Is there any way of repairing the tyre from the outside with it still on the rim? I know there are patches but these schwalbe one pro's are a pain in the censored to reinflate. Don't want to throw the tyre away as it's only done about 350 miles

  • I have these , but not used them as yet, according to the reviews these can be used whilst the tyre is still on the rim

    Might give these ago, although the flat i had on mine the other day is beyond these as it was a split across the tyre. I also carry a spare tube and a tool to remove valve on rim if need be to fit tube.
    Too many bikes according to Mrs O.
  • worms do work well. if the hole is too big for one worm try two. Those weldite kits seems to have three worms or five possibly of different sizes although the current one seems to be the thinner shorter worms only.

    There is something new coming to the market with two different worms size/lengths and refill packs.

    If riding on tubeless always carry worms some flexible superglue helps too. i find it odd that some retailers sell these tyre without informing there customers about how to deal with the inevitable.

    I always carry a tube just in case, luckily this time it held enough pressure to get me to the finish
  • I'm thinking on switching on tubeless on my MTB which is all ready for that. My question since I ride as hobby and local races only for fun is, how messy does it get if on the trail I "suffer" a puncture, which will make me fit a tube inside?

    On a road bike it's not too bad so would imagine it's the same for MTB's. Lots more mountain bikers use tubeless than road bikers so would think it would be a good idea
  • Try here. Lots of great advice and although I can’t see it on my iPhone there is a link to a video showing how to insert a worm.

    Do these come in different thickness!? The 'worms' that come with it would plug a pretty big hole, I had to trim one to make it thinner before I could get it into the hole in the tyre. Sorted it now but imagine it would be a right faff at the side of the road. Will see if it holds

    I have not had to use mine as yet, but I suppose you could probably double them up, there’s a post from cycleclinic a few posts up saying that someone is bringing the plugs out in different sizes, it might be worth contacting them to find out when they will be available

    Any tips for making worms stay in a repair?

    I've had a couple of punctures caused by little flints that don't seal on the road, then even with more sealant added, they refuse to hold under modest pressures. I've then tried worms of different diameters with flexible superglue or vulcanizing solution, but these always pop out at some point.

    Even when attempting repair in my garage, I can see the worms working their way out of the tyre when the pressure gets above a modest 60 psi or so. Looks like I an going to have to insert a patch on the inside to fix these tyres, but I have already had to use inner tubes to get home on two occasions in the last few days so I am really starting to lose belief that road tubeless is going to be a benefit over the winter.
