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

I wasn’t assuming I was the friend. But I’m close and have everything you need, plus I have lots of experience of fitting tubeless tyres now.

Ha.
Perfect. When the tyres arrive I'll drop you a line later this coming week.

Best valves out there? Had a puncture or leak the other day and when trying to reinflate the valve kept moving around and pissing air out everywhere.

Rims are hed Belgium+

How is the valve moving about. Is the collar done up tight. Which valves do you have.

Collar was done up as tight as it would go. The pump was causing the valve to move around - at certain positions you could hear the air rushing out.

I think they are wiggle lifeline valves

My wiggle ones have been ok . Pushed them down tightened up the o ring then collar all good. Have used a track pump instead with the valve at 12

How are those wheels? Still going strong?

Rock solid. Hit a few puddle hidden potholes recently and thought 'shit, that's the wheel ruined' and they just keep going strong.

Effetto Mariposa valves FTW you can get them nice and tight without destroying them, Muc Off seem to be similar.

Not surpirsed by that, rock solid.

Sound like there is a rear in the tape that movement in the valve lead to a leak. It probably not the valves fault.

First time ever trying to tape a rim ended in expected misery. Air gushing out the valve hole, makes me wonder if the three tape passes over is too much and preventing a good seating for the valve. There’s no sealant in yet, but I don’t remember previously having to use this to seal the valve.

I have 3 layers of that tesa stuff in a wheelset and it works.
But tubeless can be slow and annoying to set up.
Good luck getting it sorted.

Reinstalled the valve, wounding up valve too tight can actually cause issues, if you have another valve, try it.

Thanks for the tips, i’ll See what happens with a different valve.

Make sure you only make a tiny hole in the tape for the valve to fit through

There seems to be some conflicting advice about the hole size. Logic says, as you do, that the hole only needs to be big enough, whereas a Stans video suggests you file the edges down (for a better seating, I guess).

I've found the best approach to making the valve hole in the tape is to heat up a crosshead screwdriver over the flame of the gas range and then use this as a hot poker to melt a hole in the tape through the valve hole.

There seems to be some conflicting advice about the hole size.

I did see that too, in the end I just prick the hole and push the valve in (all tubeless installation were using Stan parts), the main issues were merely the tyres not mounting/not enough rim tapes.

I just shove a screwdriver through it from the underside. then mash the valve through, as above. Nothing special to it.

Think I'm going to start again, might as well get some use out of the mahoosive roll of tape.

Quick question - how easy is it to mount the tyres?

Super easy. They're Schwalbe Kojaks on a Velocity A23 (tubeless ready, I'm assured). Not specifically tubeless ready tyres (this is an experiment), but they seem to hold the pressure up to about 90psi before all the air escapes out the valve hole.

Super easy.

It shouldn't be this easy, but then you did have a non-tubeless ready tyres, my experience is only on tubeless tyres and it should always have a tight to near impossible fit (pray it's not the latter).

Sound like you answer your own question TBH; replace valve.

Yeah, my former experience of Schwalbe's (Pro One TR, Marathon non-TR) has always been painful, as you suggest, so it was a pleasant surprise when it went on without too much of a fight. Just annoying the issue seems to be the valve. Hey ho!
