Was out yesterday on a fairly new to me bike. Previous owner has been running tubeless tyres. Needless to say I got a thorn induced puncture miles away from home.
What are you supposed to do? Put more sealant in somehow? I tried shoogling it about to see if the hole would seal to no avail. Tried to stick more air in but only succeeded in unscrwing the valve core thingy.
In the end gave up - and stuck in an inner tube. Sadly I then pinch-flatted about 10 minutes later. Annoying.
If anyone can explain this seemingly arcane art to me,and why I should b persuaded to try and persist with it, I'd be moderately grateful...
How much sealant was in the tyre when you put the tube in? It should just seal up
How old is the sealant? Its a pain, but I think it is only effective for 5-6 months before it should be replaced. Other than that, I would expect a thorn puncture to be sealed pretty quickly. Did you pull the thorn out? you can leave things like that in and they'll often just seal over pretty easily and you'll never have to worry about it!
Quite a bit. Obviously I wasn't carrying any, but is the idea that the milky sealant stuff just fills the as you stick more air in? I may give it another try.
My experience so far has been so easy, gaffa tape and electrical tape, some art latex, screen wash and a track pump with two single ply high rollers....sorted...sealed very easily and have stayed up so far, all good, stick with it dude.
Don't bother with latex sealant it just gets everywhere when you puncture and if you have to get the tyre off to put a tube in it makes everything messy. I only use a little sealant when fitting a new tyre just to seal any porosity in the tyre.
Get a tubeless repair kit and a small tube of superglue. If its a small thorn hole you can quite often glue it closed by pinching it open, applying drop of superglue and pinching closed for a minute or two. No need to take the tyre off. If its a bit bigger then use the tubeless repair kit and again no need to take the tyre off. If its something bigger or you can't be bothered repairing on the trail then take the valve out and stick a tube in until you get home.
Advantages of tubeless for me are being able to run tyres approx 10 psi less with the same rolling resistance which gives better grip. The tyre is thicker so better puncture resistance. No chance of snakebites either.
Good videos on Stan's website explain how it [i]should[/i] work

Hole was too big for sealant to fix.
Blow up tube more.
p.s. I don't run sealant - just use a tube if it happens.
p.p.s. Not all tubless tyres are created equally.
Yep, I've been feeling a bit conned with the sealants, even Stans seems to struggle with small pin hole punctures.
i bought some thick wool and a couple of thick blunt needles, the idea being if you get a wee puncture like that you can tie a knot in the wool, thread it through the hole with the need, then pull the needle back out leaving the wool behind. the sealant should hopefully gum up around the wool and seal the hole. Haven't tried it yet though...
The Weldtite sticky string repair kit is great - works a treat and you can do it on the trail without having to remove the tyre.
(I'll happily demonstrate and repair your tyre for you - am only a few miles away from Musselburgh.)
+1 for weldtite but not so great on the trail! Punctured a nobby nic on some glass so it spewed sealant everywhere. Fixed the puncture the day after and it was spot on and has been great for a year.
I like Stans sealant as it works well for small punctures but make sure to get the particles in or it won't work.
