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

Well the gorilla tape held...

I won't forget that thud for a while!

Considering a new wheelset next year, looking at grails on hope hubs, considering these are tubeless ready, what are my options for tyres? As a guide I like to run 32mm paselas and gravel kings, so looking for summat similar, 32mm is my max.
Cheers

Gravel kings work tubeless, I think paselas might as well?

I'd not recommend using gorilla tape - it's ok to get the setup working, but causes problems down the line. The sealant can get under the tape and make it unstick quite easily, and, worse, the gorilla tape can leave residue on the rims and tyres which can be really difficult to remove. This can give you real problems with seating the bead.

I did not know that. Excellent, will stick with the gravel kings.

G tape is fine. All the tapes I've used can cause problems if you make a mistake while doing the install. If anything, G tape is more forgiving than Yellow, because it doesn't require a clinical-clean rim to install, and comes away in one piece.

Just make sure the G-tape is slightly wider than the rim bed once pushed down, forming a U shape and riding slightly up the sidewall of the rim. Then the edge of the tape is sealed from the sealant by the tyre bead once the tyre is installed and mounted.

Possibly - but there's still the danger of tape residue sticking to the tyre.

But thinking about it, you may be right - I've always trimmed the tape to have it not go up the sidewalls. Might have exposed the edges of the tape to the edges of the tyre. Hmm.

Dunno, never seen this. How does it happen? I have five wheelsets set up with G tape - XC/AM, Gravel and CX/Road. All fine, bomb proof set-ups.

Might have exposed the edges of the tape to the edges of the tyre. Hmm.

Yeah - this is where you might find the tyre pushing the tape off the rim when you come to dismount it. Which sucks.

I think in previous set-up guides I've suggested trimming the tape back so it sits flush with the rim bed, partly because I believed the 'bead hook' was involved with retaining the tyre, and tape riding up the hook would somehow interfere with the bead lock and increase the chances of a blow-off.

But now I know the hook isn't such a big deal, and that the tape gets compressed flat anyway, I'd recommend against that, and let the tape ride up towards the hook to improve the durability of the install.

Or something.

S-Ones in grail rims fit easily, i even pumped them to 100 psi and didn't exploded

Just spent an unhappy hour trying to install some tubeless. I just can't see how I'm supposed to get the bead to seat.

I'm using S-ones on a set of Alex rims, however when installed with no air in it the tyre sits low in the rim bed with several mm of space between the bead and the internal edge of the rim. I've tried manic pumping and loads of bubbles, but air just flows out freely. I've tried using an inner tube to at least get one side of the tyre seated but as soon as I deflate the inner tube both beads appear to come away from the rim again.

I haven't tried with CO2 or a compressor yet (lost the head of my CO2 pump and will try making a compressor this evening) but even with the increased pressure I can't see how the air won't instantly flow out of all the gaps?

If the home made compressor fails try leaving a tube in overnight. If the tyre's been stored folded up it can take a while for the bead to conform to the rim.

Yup tyre was originally folded up although they have been stored hanging in my garage for a week or so.

Alternatively the local garage may be open tomorrow so might be able to try their compressor.

Make sure the collar holding on the valve is as tight as you can get it, I had real trouble getting mine seated when it turned out just enough air was leaking from around the valve to stop it sealing.

Gaps are normal.
You're going to need way more volume of air at a higher rate for the bead to 'pop' onto the rim. Only been lucky once with a normal pump.
Try the ghetto pump method, should work a treat. Compressor is slightly excessive. If you take it down to any decent bike shop, they should have the tooling to do it pretty sharpish.

I've tried manic pumping and loads of bubbles, but air just flows out freely.

You need another layer of tape. Don't waste a CO2 on it if a track pump won't even push the tyre about a bit.

As @howard suggests, use another layer of rim tape.

Also invest in a charger pump, it makes life so much easier.

i bought one of the Bontrager TLR charger pumps and have since found life much easier

Perhaps we need a list of people with charger pumps and locations

Actually scrap that my ancient specialized floor pump is on the way out, might get one of them newfangled things

Stretch the tires with tubes. Put some layers of rim tape, two or more. One thing I noticed it makes a lot of difference is soapy water, make sure the rim and tire is well lubed.
