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

Shout at it until it works

I've tried that. That's basic home spannering.

Thanks guys for the insight. I will now read the whole thread. Also, is there still a poll function?

Get gp4000 rs

My ghetto tubeless Kojak setup

👀

I read theses tyres were terrible to tubeless? Deets please.

RS?

Conti's rumoured tubeless tyres?

Edit: nope, just lightweight GP4000SIIs.

just lightweight GP4000SIIs.

You can get the same effect by using part-worn GP4000S :)

Just stans tape on Pacenti CL 25 rims, stans valves and stans sealant. Ran them like this for a couple of years but let them dry out and go flat when I was using another wheelset

Cheers, good to know.

Fuck it, gonna do it.

My main reservation is I don't want to buy a great big spacepump or have to rely on an LBS. How the FUCK do you get the tyre on the rim with no inner tube?! Do you just line it up and blast it?!

Now that you are taking the plunge you will get suggestions but this is my method:

1. Remove old tape and clean the rim with acetone
   
2. install new tape, do a good tape job, maybe even 2 layers
   
3. Make the tiniest possible hole for the valve in the tape
   
4. insert valve, tighten (by hand) the O ring
   
5. sit both beads ideally without tyre levers, helps if you make sure they sit in the middle channel
   
6. pump and pray that the beads lock, they might not hold air until you add sealant but they have to lock in place
   
7. if/once they do remove valve core and add sealant
   
   

Ride into sunset.

I have never had to use compressor/weird pump, I have done about 10 wheels.

@amey has pretty much nailed it. On my American classic 420’s I needed to use a soap and water mix to lubricate the rim to allow the bead to slide into place, if I don’t the bead will not pop into place. on my Fulcrums I don’t need to do that.

Thanks lads.

My rims are tubeless and as smooth as heck inside already.

I admittedly haven't looked into (googled) it yet but I can't fathom how the air doesn't just piss out when you pump up before the bead has popped in...

I often find having a bit of sealant in the tyre helps get the bead to pop into place.

I guess as the air tries to escape it drags some sealant between the tyre and the rim, slowing air loss and helping the pressure rise to aid the bead-pop to occur.

It's a black art isn't it. I'm excited about it now but there will be swearing I'm sure.

I've got an airshot type thing if you're anywhere near North London.

I used an airshot on pre prepped new tubeless wheels. There was an initial problem because the bead wsnt mounted properly. Or in properly.
It didn't go up. I worked out the problem. It went up next go.

I’ve never needed a weird pump or to use sealant to make the tyre bead seat itself. Welcome to the future.

weird, i always used sealant before pumping.

I’ve always pumped it up, seated it, removed valve core, inserted sealant, reinflate after replacing valve core. Which I’m pretty sure is what Amey said above.

Yeah same, although I had trouble sitting some pro ones on DT R460 once, I did sealant first then gently rolled the wheel and inflated .. worked!

There are way too many factors to have just one method.

Is no one doing the aerosol and lighter thing to seat their tyres like 4x4ers do?

You first. Tell us how it goes.
