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

^^ INRATS

Are all tubeless gravelkings shit or just the GK/slicks/whatever?

They're fast but not durable.

Mine are shit. I've given up on them.

Thanks. Shame cos the new purple ones would look great on my bikes 😪

Yesterday I thought I’d clean out the old gunk from my tyres after a year of going tubeless it was a bit minging but ok. Bit of a bastard getting the seal again with just a track pump (used an inner tube to get half the bead on properly first) but I felt job done. Just went out to the garage to do the recycling and discover it sitting there with a puddle of gunk under the back wheel.

Remind me why tubeless is a good again? Sigh

Because now you're tempted to buy new tyres when you don't really need them just because it's easier than cleaning the gunk out the old ones and getting them seated.

Oh wait, you meant why it's good for you not for tyre manufacturers...

Going on my first bikepacking trip since converting to a tubeless religion, will have 2 tubolitos + 2 regular tubes as backups, the tyres are new and just set up. Should I carry a small bottle of sealant? Will have plugs/boots and all of that jazz

How long are you going for? I did two days of SDW on relatively worn and weepy tyres with nothing but some plugs and topped up sealant. Despite all the flint I didn't end up using any plugs, but I do still have quite a bit of sealant all over my seatpack (not sure how to get that off tbh)

I didn't even take a tube, but I was aware that I was taking a bit of a risk

I'll be gone for 10/11 days in Scotland, a couple of places quite remote as well

I would. But only if you can reseat them with your hand pump. Given your running 40c ? You can expect to puncture and tear them, which might mean you loose the sealant.

But I also don't bother carrying sealant. If its bad enough you loose it all, you're unlikely to fix it with more!

My thinking indeed, yeah will be on 40/45c.

Pick one!

Don't bother. I'd dump the tubolitos and take a 3rd proper tube. .
And be persistent getting a worm to hold air. Even if you need to ride/pump for a bit, because once you go to an inner tube, you can look forward to fixing flats a lot.

Also I use way more sealant than the box recommends. Suggest you do same.

That's a good shout

I am also thinking of adding more layers of tape to make sure the setup is extra snug and won't unseat even with the tyre completely flat.. Is that stupid?

I guess it depends on your set up but from my experience, tubeless tyres are tight and really rely on the channel in the middle of the rim to allow them to be fitted and removed. I wouldn't want to be snapping tyre levers trying to get them off when you've punctured in the rain and can't get the tyre off the rim because it's too tight after 3 layers of rim tape

Makes it harder to seat too though.

I can get them on by hand now, they seat nicely (even if I have to pump to/just above the max pressure recommended for the tyre) and stay seated even without any air in them, but unseat at the first gentle push. This is all in the dry and cozy environment of my flat.

Hence my thinking of adding one more layer

More tape layers might smooth the shape of the bead retaining lip in a way which makes it worse at its job

Good point.

Will try a getting the tyre wet to simulate conditions and drop the pressure, to see if it holds in place as is

You could be overthinking this a tad

He's an engineer, it's not his fault.

Then picking the right tyre for the terrain and riding style should be easy, tubeless is then even more reassuring

Why not just whack a load of sealant in there, pressurise it and see if it leaks? I mean, if it was like my brand new WTB tyres, they'd have a punctured sidewall from new, but it was nice to know ;)

Imo deflate the tyres and see if the beads unseat. If they do don't bother taking anything except plugs, spare tubes and tube repair kit.

If they stay seated, it could be worth taking sealant (they do those small pouches and small bottles). Also tell me what the rims are because mine are crap and lose the tyre.

If they come unseated but you can reseat them with a hand pump you might as well not bring any tubes and just have loads of tyre repair stuff like needle and thread, tyre boots, gorilla tape/glue etc. Also tell me what the pump is.

Other option is using co2 to reseat them but who can be bothered.

Another possibility is taking a valve adapter so you can use the air compressors at car garages.
