after buying a set of crossmax ST's from gonzalo and after chatting with him about the wheels and already knowing that i would be buying a new rear tyre, i decided that apart from replacing the bearings, now would be a perfect opportunity to try out tubeless to see what all the fuss is about. the general feeling is that a normal track pump is enough to inflate the bead onto the rim. so i attempted to use a track pump.....not a chance of seating the tyre onto the rim, so i thought ok maybe its my pump that doesnt deliver enough air. so back down to JEJAMES for the guy who sold me the tyre to infate it with their compressor...............NOT EVEN THE CHUFFING COMPRESSOR WOULD DO IT! guy says, " yeah because the tyre has been folded for a long time, its best to put in a tube, so as to form the tyre back into its proper shape, leave the tube in for a few days then have another go at inflating it tubeless" so now im thinking i might need a new track pump, i might also really need a compresor and even then its a chuffing faff! i havnt even gone tubeless on the first tyre yet and its already reminded me why i havnt tried it before.

I've never managed to seat a tyre with the track pump, I took low coggers home made compressor design and it works a treat. All for about £8.
A bit of soapy water on the bead helps too, what tyre you trying to get on?

my tyres were hans damp...i had no problem with them and just a track pump...no problem at all...you just need to make sure you try to put the edge/bead of the tyre as much close to the edge of the rim as possible. And when you pump the tyre with a track pump, you need to do it quite fast and vigorous...but a piece of cake...any problem, bring it over to mine and ill do it for you. However there is a ghetto option
but seriously, bring it to mine and ill show you how easy it is.

Iv got loads on with a track pump Cheap nasty things from lakes, it takes a lot of sweating and swearing but it will go on Yes a new tyre that's been folded will be a pain to get on Either put it on with a tube for 5 10 mins then pop the tube out, leaving one side already seated then it's just one other side to do Or get a friend to help you and pinch the tyre at points around the wheel to pull it apart so it semi seats so when the air goes in it seats that bit easily We have now got a track pump specially for tubeless and not taken longer than 2 mins to do on yet, similar to the pikey way it has a chamber you till with 180 psi then push the button and it dumps the lot into the tyre in a split second, A bit far away Your welcome to pop round any time and I'll put them on for you one handed As above soapy water the crap out off thr beads while your doing it as it helps it seal a bit rather than letting air out and it shows where needs pinching because it loosing loads of air soon as you pump Tubeless can be a nightmare to set up and you get covered in the latex but when it's up its great, no worried about thorns or glass etc , iv unseated one tyre over the peaks but I was hammering it down and maybe a tad low.pressure in it, Chuck a tube in as you would normally and carry on, It says like 60 ml fluid in a tyre.. iv got about 130 140 haha not fussed about the weight saving But will seal more holes before it runs out

yes...folded tyre could be a pain but even that i have done it...it proper Schwalbe tyres and the excellent Mavic system it is very easy...but inflate the tube on the tyre (not i=on the rim just to give it some shape...come to mine and ill do it for you.

I use the 2l pop bottle method and a bit of soapy water round the rim!, works a treat

Basically G sold you a dud wheel... I've offered many times to do it myself! Those Mavics almost inflate themselves! Had the same ones on the 29er before with the same success rate! The key is the vigorous pump...like your brain is going to explode!

i think its the shape of the tyre wall or the pump thats not delivering enough air or a combination of both. iv just had another go at it. conservatory floor is wet through with sweat, and its still not on..........bastard tubeless!!

Have you put a tube in yet?
Pump it to like 50 psi and bounce it about a bit give it 5 10 mins
Take one side of and pull the tube out
Pop the valve in and some fluid pop that side back on and go like a maniac Atleast it's then only one side to seat and other side is already well seated

yeah iv had the tube in all day. already done that jack except havnt put any fluid in yet. i want to pop the beads in before i put in any fluid.

Post by jack on Jun 15, 2016 21:23:06 GMT
You need to put the fluid in so when it's sealed it's sealed
When you've put it in spin it around a bit so the fluid goes to all the edges and helps it seal

the fluid isnt needed to pop the bead in.once the beads in, the tyre can be deflated and the beads should stay in, then squirt fluid through the valve with the core removed. my problem is that the tyre wall is no where near seating to allow the pressure in the tyre to increase.

Post by jack on Jun 15, 2016 21:48:58 GMT
That's where the fluid comes in handy
Some of the bits that aren't sealed will be covered in the fluid so stops the air leaking out so fast, iv always inflated it with the fluid so that covers the seal and stops the air blowing out so fast

Can you not use a rope or ratchet strap around the centre line of the tyre? Should force the side wall and bead out to the rim.

i understand what you're saying jack but because the tyre bead isnt anywhere near seated, the gap is too big for the fluid to fill the gap. in theory the tyre should inflate with no fluid and pop the bead on. once the bead is on, the tyre can be completly deflated but because the bead is in place there are no large gaps so then the fluid can be put in and it should then be easy to inflate the tyre with a track pump. if id tried to put in the fluid before trying to inflate the bead on, there would be fluid all over the conservatory by now.

Should force the side wall and bead out to the rim. tried that dirky but with alot of large zip-ties connected in a loop.it still didnt press the wall against the wheel, just squashed the tyre into the wrong shape. i used this method a while ago to re-inflate a trailer tyre and it worked fine.

Worst trouble I had was last time - same as you a tyre that had been folded for yonks - no way would that muthafecker seat in the bead. popped a tube in - inflated it to about 50 PSI - left it for 20 mins - tube out, soapy water on tyre edge and rim bead, inflated and stayed up with a track pump no probs. Then,as you say once you've had it inflated with no fluid - valve core out and fluid in through the valve. Pffft - easy peasy

its a shwalbe hans dampf evo tubeless ready whats coggers home made job? iv seen them made from a pop bottle or im thinking of trying to make one from a fire extinguisher. or if i have to buy one , look for a mini compressor to use from my car cig-lighter Scroll down here mate, mtb-uk.co.uk/thread/3731/recommend-me-compressorAll you need is an old presta valve and screw it in on the blow off valve, then the tube goes over your valve on the wheel. Put the tube through the ring end of a spanner to close it off. Pump up the bottle to about 70/80 psi, remove tube from spanner and the air will flow through popping your head on the rim. I put the sealant in the tyre before seating it, then give it a good shake.

When inflating hold the wheel so that the valve is bottom most, and push on the tyre a little bit...
Or buy a compressor...
