Why didn't tubeless puncture seal?
This has happened a couple of times in the 5 years I’ve been tubeless but I remembered a tip I was given some time ago
Take wheel out & hold it so the hole is at the lowest point of the tyre & put a finger lightly over it – not to stop air escaping but just to slow it down a bit. Worked for me both times.Posted 6 years agotomdSubscriber
This has happened to me a couple of time. For me the sealant was almost new so hadn’t dried out and still had plenty of the latext crumbs so it wasn’t that. I think it was to do with the tyre I was using in one case and the other it was the location. The tyre had pretty thin walls so even though the cut was small it opened up and wouldn’t seal very well. I got it to seal by letting the pressure down as low as could be riddena and gave it time to seal up. The other time it was close to the bead and wouldn’t seal because of the flex I guess.Posted 6 years agocookeaaSubscriber
I’ve Had a Similar problem once with a Speccy Captain tire (Probably alot thinner walled than your Bonty), it was more of a cut/slash (About 4-5mm long) than a nice round hole which I think must have an effect on the sealing. The tire was older and the sealant was maybe 3-4 months old and should have been topped up.
The sealant sort of still worked and it became a “Slow puncture” rather than an instant deflation job but I thought it better to bung a tube in for the ride I was about to go on, got it home, Cleaned it up and patched it properly, rode it tubeless for a few more months after that, the tire is still in the spares pile.
The thing with tubeless tires sealing up cuts and holes really is down to a few factors, the sealant you use and how old it is/how much you use, the construction of the tire – it’s resistantce to different types of damage and the geometry of the damage – a hole/cut/slash of full or partial depth…
Some tires are more resistant to holes and cuts than others – I’ve got an IRC Tamashi DH in the Garage which I believe could withstand sustained small arms fire, the trade off is that it weighs the same as the moon, fitting it to a bike and riding it could well cause a Tsunami in Kent I reckon…Posted 6 years agobigjimSubscriber
Did you pour the liquid from the bottle with the bottle upside down when you were setting it up? Without the particles not much will happen I suspect. I would think it would fix a 3mm hole as it seals the hole in the bottle pourer when you try to pour it upside down!Posted 6 years ago
