Tubeless Tyres -"saying the same things about tubeless tyres over and over again" Hippy read the first f**king post

gave my old orange one to the missus :)

Oompa Loompa comedy night.

I had my first ever tubeless MTB tyre puncture the other week. Downhill casing too, so I must really be shredding hard. It sealed before I'd even noticed, and I carried on with my day.

tl;dr: you're all riding tyres that aren't thick enough.

tl;dr

Orange Seal regular for under 35psi
Peaty's Holeshot for higher pressures
Stans Original good at low pressures, Stans Race good across all pressures but dries up quickly
Silca shite

Anyone using Michelin Power Cup Tubeless?

Just limped home because I got in my rear tire that all my sealant pissed out of and I’d left my plugs at home in my Carradice.

Now I’m at home do I just plug it or since I’ll be de-seating the tyre in order to put more sealant in anyway should I put a patch inside the tyre? Will a standard Rema inner tube patch do? Plug it as well?

I’d patch it. Just use a normal patch and glue.

Patch it. If you can see through the hole you need a mushroom thing like this.

Could see the city but not through it so have patched it with regular patch.

Needing more sealant now so will pick up a repair kit at the same time so I hopefully always have one with.

Seen this impressive plugging contraption being carried out on the ride last weekend, pretty extreme fix, I would have put a tube in long before that.

Large hole (maybe 1.5cm?) in a Schwalbe 2.2" (Rocket Ron?). Double car tyre plug fitted (already surprised someone had those on the ride), the plugs sealed, however they would slowly slip out while riding, so tyre unseated and two further plugs (one car one regular bacon strip) threaded through the first two from the inside to stop them coming out. Reseated the tyre with a cartridge, pumped, trimmed the excess plugs and rode another 100km with no issues.

I suppose that counts as a win for tubeless..

Serious question;
Before tubeless did we avoid sharp stuff out there better? Because I can count on one hand the amount of times I had or even saw a slice in a tyre that was so big that you had to reconstruct the tyre on a ride to get home, before tubeless, but now it seems a normal thing to see.

I would be riding Marathon tyres which are much tougher, isn't the point of tubeless
you can ride thinner tyres and lower pressure for speed and comfort ?

I was definitely riding more carefully, slower and less gnarly stuff. For the record, that puncture happened in a place where I have slashed both tyres at once on a previous ride.

I wonder how much of that is the parallel rise of social media, meaning we just see more stuff in general. Tubeless was becoming the norm in mtb around the same time as instagram was becoming kind of universal I reckon

Definitely more blase when riding tubeless.

People are riding thinner tyres thinking punctures will heal themselves

It’s also a Thunderburt I think, which in my experience are made of tissue paper

Oh don’t get me wrong I’m just a guilty of being more reckless on tubeless, so when it goes wrong, it goes WRONG.

Yup.

is there a good way to get older floppy tyres to seat?
I’ve got some gravelking SKs in 35mm that I’m trying to mount to a Panceti Brevet rim. The tyres came used on this bike but clearly have been setup tubeless before. They were very easy to get on and off, the bead feeling ‘looser’ than what I’ve come across before (never had these tyres before, but have just finished putting some Pirelli 45s on my grav bike).

I’ve put straps around the circumference of the tyre/wheel but it just won’t hold air. The beads are just sat in the middle of the rim and air is just blowing out like wind through some curtains.

Do i need a compressed air thing for this?

You could try CO2, I use that to seat a tyre.

I've never used CO2 but I have made my own tubeless inflator with a coke bottle and a couple of presta valves. That or a booster pump has always worked.

Can you massage the tyre onto the rim edge a little? That plus a bit of water tends to do the trick for most tyres
