Howdy. I have a new-ish road bike that has these newfangled* tubeless tyres. Yesterday, one got a puncture. Latex spewed out for about a minute, I spun the wheel, it sealed itself. Added some air, good to go. Excellent.

But is that it? Is the tyre now properly fixed, good as new, or do I need to do some repair work before the next ride? Ta muchly.

Assuming the same applies on road bikes as for any other bike type, just keep riding. You might need some more air in the tyre, but if the higher pressure still holds then it'll be fine.

You don’t need to do anything, that’s the point of tubeless - it seals smaller holes itself. Larger cuts and holes near the rounded edge of the carcass can fail once sealed though. When it works it’s great, when it doesn’t it’s a messy, frustrating nightmare.

If you hevent already, I would clean off any latex that’s sprayed on the bike - it goes bloody hard if left too long.

I'd possibly also top up the sealant.

I'd probably add a bit of sealant too.
If you topped up with a c02 canister, you should let the tyre down when you get home and re-fill with air. c02 will make the latex dry out.

Erm no, the problem with CO2 is it goes in damn cold and that thermal shock causes the issues, replacing the CO2 later has no effect.

A while ago i took my mtb tyres off to check the sealant and top up etc and i found 6 or 7 thorns which had gone all the way through. I pulled them out, refitted the tyres and all good to go. Needless to say i didnt know anything about any of them when they happened.

Over the winter it sat for a few months without use and the tyres stayed inflated, but had dropped a bit.
My other 2 bikes with regular tubes and tyres, both of which are new, go flat in a few weeks.
So for me tubeless is a winner :-)

What would the other option be? Throw the tyre away and get a new one? Just like you do when you get a puncture with a normal set-up, replace the tube, get home, throw away the ty....oh wink

It can react if you spray the CO2 directly onto the latex but you can just have you're valve at 12 o'clock while inflating to avoid this.

You need to remove the CO2 afterwards as the dry air causes the latex to lose it's moisture.

That doesn’t make sense to me, any moisture that the latex has lost to the CO2 atmosphere will be lost when you let the tyre down, won’t it?
