It's been a frustrating few hours in the yourguitarhero household trying to get some tubeless tyres to seat on tubeless rims....
Got the valve cores out, fairy liquid on the rim and tyre bead and hitting it with 70psi out of an Irn Bru bottle.
Success eludes me.
Anyone local who could help me out for a few bottles of beer?
Hmmm, you might have to treat yourself to 3l of cider and see if the extra volume of air helps.
Does it feel close to seating?
Where in Edinburgh are you?
I feel for you, it is frustrating.
Not sure what you have tried already but i had success with the following.
Stick a tube in for a day to help mould the tyre a bit and hopefully pop the beads in.
Remove the tube, trying to leave one of the beads in. Put valve in, put sealeant in and dribble a bit around the beads. Apply air as fast as possible - gas cans are good. Hopefully all should seal.
Hope this helps.
as above, where are you based and what set up are you using?
I would definitely get a tube in there and pump it up good and hard. Leave it over night and try again tomorrow.
What tyres/rims?
If that fails, then I could give you a hand probably, mail in profile.
I don't know, I've just put some Clement LXV tyres on, which apparently aren't tubeless ready and they went on and up in about 15 minutes tops. With a track pump. 2 scoops of stands in each, a little tweak to pull the tyre beads out of the rim well and pump pump pump pump.....
Is everything clean? Sometimes you just have to keep pumping 😯
I'm in Edinburgh but wouldn't be able to help until the weekend and even then I'm hesitant to help with tubeless set up, although I've got it pretty sorted on my setup, just done two hutchison tyres on wtb rims in about 20 mins tonight :p
some suggestions in the meantime-
1) don't use fairy liquid, use soapy water, as in the old skool bar of soap. fairy liquid doesn't have the same slippery characteristics and foams up like a mother.
2) as above, use a tube first, get the beads popped onto the rim, leave overnight to straighten the tyre bead out. remove ONE side of the tyre from the rim only and take the tube out, then carefully put the side of the tyre back on. now you only have one side to seat.
the bottle of pop compressor should work on one bead, especially with soapy water. make sure the tyre is over the valve hole and the air isn't just pissing out a massive gap
I don't put the sealant in until I've got both beads popped on, then I just let the air out, sealant in the hole, and valve core back in and pump up.
what is the tyre/rim combo?
+1 for a tube in overnight.
But you shouldn't need to put any sealant in (other than around the valve) until it's all mounted properly.
In Balerno, have compressor, email in profile.
The only thing the compressor has failed on is a wire bead Knard so I'm stretching the tyre with a tube first of all and will try again soon.
The wheels are Superstar Sentinel. They have Tubeless Ready written on them.
The tyre I was trying was a brand new Bontrager XR3 Team Issue, again marked as Tubeless Ready.
It did come close to seating at one point.
I've chucked a tube in it this morning. I will give it another try this evening and I'll try using the soapy water instead of Fairy Liquid.
I'm also going to try my rear wheel today. It's the same as the front, but it's a used XR3 tyre.
If there is still muchos swearing I'll give one of you guys a shout - that compressor sounds good AlasdairMc. (You didn't work at RCAHMS did you?).
I stay in the city centre but have a car so can drive to one of you guys.
Tubeless ready? Have you installed rim strips in them?
If you're using a pop bottle, make sure you take out the valve core on the wheel's valve. As someone on here suggested, do that and you can make a quick switch to get it back in without losing too much pressure - then top up with pump. I'm near penicuik and in tonight if any use - AMc's offer of a compressor should be more tempting though!
When you hit it with the compressed air bounce it around a bit.
I gotta say from a google image search those rims don't look like they will be very good/easy tubeless, there is barely any shelf for the bead to mount on, are they supposed to be used with strips?
garage compressor is the way forward if you cant get it with the pop bottle.....
spent ages trying to get mine on and had to resort to going to the local tyre fitted and using his compressor and job done. I even snapped my track pump in the process
I'm out Musselburgh way if that's any good to you. I've never yet been defeated by a tyre / rim combo over last 4 years.
Well guys, thanks for the kind offers, but I have succeeded!
My method was as follows:
Re-do the rim tape (Superstar tape). Wasn't that neat. Got my wife to help me, she is a pro milliner so that kind of thing is her forte.
[list]Get one tyre bead on
Put in an inner tube
Put the other bead on
Pump up to 50psi - heard a few pops/snaps as it settled into the beads
Deflate and pop tyre off one side
Put in a Stan's valve with core removed (I got a little Park Tools tool for it, VC-1). Add a little sealant around the hole as I was putting it in
Push the tyre back on by hand after rubbing a wet bar of soap around it
Do the Irn Bru bottle trick at 70psi - got the bead on and the tyre up to 20psi. I put a cable tie round the tubing at each end as it popped off one time
Did the trick again, just in case. Tyre now sitting at 40-ish psi
Deflate the Irn Bru bottle
Put sealant in through the open valve
Put the valve core back in
Pump up to 40psi
Spin the wheel around[/list]
Have now left them sitting flat and will see if they still have air in the morning.
good stuff. the stan's shuffle is good, shake the wheel sideways working your way around, though spinning/riding is probably as good
Shame you forgot to take the tube out 😉
I found it helped to have the wheel off the ground slightly - hooked on a nail in my case - so that there wasn't the low spot on the floor causing the tyre to spread open more with respect to the rim. Off the ground you avoid that weak point.
Well, one of them's gone flat already. Stuck it in the bath and lots of little leaks all round the edge of the rim.
Looks like I'll be giving it another go later!
sounds like you need to do the stans shake - see their how to vids, shaking the wheel & laying the wheel down for a few mins either side to get the goo to do its job all round the tyre - spinning will only get the goo to the inside of the tread rather than the side walls
bad times. did you put enough sealant in? looking at the rim profile, I'm just not sure it is going to be an easy job, the bead shelf is so narrow compared to stan's or other tubeless rims

Put more sealant in and go riding. The Stans shake is useful but riding the tyres and bouncing them around properly is the best fix. It may not be immediate either, I've had tyres that have taken a week or so to finally seal up.
I didn't work at RCAHMS. I had to Google the acronym...
OK cool, will give it test ride after work.
No worries Alasdair - I used to work with a guy who mountain biked there and lived in Balerno. Must have been a different Mc at the end!
Well, trials and tribulations continue
One wheel is OK, another isn't happy.
Can get the bead to seal on it OK, but leaks air around the valve hole.
Tried re-taping the whole rim, putting on o-rings and using a different valve (a Roval one instead of the Stan's one). Still leaking.
Think it might be time to take it to the bike shop!
Did you put two layers of tape on? And is it stretched properly tight?
It sounds like that might be your issue, maybe get another person to help you stretch it tight.
