UST tyres and punctures

[up-the-dubs]

So I have a set of tubeless Hutchinson Spiders and the rear has (as I found out while quiet in work yesterday evening) 3 slows and a loose spoke nipple where the air is leaking . The nipple I assume just needed tightening (too busy to check since) but whats the story with patches on UST tyres? I went to sand a little for the patch but the threads are right at the surface of the tyre so this cannot be done.

Basically, is the tyre repaireable or is it goosed? Not too bothered as I have another marginally worn tyre in the shed, but a repair would be nice all the same.

Ye gods how I hated tubeless tyres on my road bike. Got rid of them as soon as finances allowed.

I take it these are some newer fancy ones, and not ones that were tubular in cross section and had to be stuck down with glue, like mine?

No, essentially regular tyres but with a stiffer bead around the rim and wheels shaped to match. The tyres pop into place with high pressure like car tyres. Allows you to run very low pressures (which I don't) if desired. Not exxactly sure why I use them but this is the first time I've had them punctured, and they're in great nick otherwise.

Don't ever try the old ones. Massive PItA.

You can get that goo stuff that seals punctures for you. I seem to remember seeing a video of a demo where the guy just kept banging nails into the tyre and it kept sealing itself. Very impressive, but since the whle point of tubeless tyres is presumably to lose the weight of the tube, I'd be concerned about how much the goo weighed *OR* switching back to standard tubed tyres if punctures were a big problem.

Cheers,

It's not so much a big problem (a swift pump up each time before a cycle does them for a day or two) and I've never had to fix a puncture out on a cycle (touching solid oak!), but it would be nice if they could be repaired. I've thought of the goo, but as you said, if it clumps up in one spot after the bike sitting for a while it could add a bit of weight, plus as a tyre depot manager, the mess that stuff makes is a curse on car tyres so I'll avoid that one anyway . I carry a tube for emergencies anyway .

Random suggestion - a blob of mastik or araldite or something just over the hole (inside) instead of a patch?

and double You've done it now! Puncture fairies are gonna get you for sure.
