Seating UST tyres; do CO2 cartridges really work..?
Received a Conti Rubber Queen 2.2 UST tyre today, and it refuses to seat on my XM819 rims with a track pump. The Schwalbe Alberts 2.25 UST’s I’ve had for the past year or so go on and off by hand, and seat no problem whatsoever.
So, having never had one before, do CO2 cartridges really work for getting that initial blast into the tyre and pop the beads into the UST rim?

never had a problem with maxxis UST, I’ll be interested to hear about how you get on with the queens those must be one of the first UST sets in the country! you do realise that you’ll probably have at least one member of STW staff offering you all kinds of favours in exchange for them don’t you 😀Posted 9 years agohousehusbandSubscriber
Thanks all – SKS Airchamp and spare cartridges ordered.
cynic-al; there was sealant remaining from the Albert I’d just taken off, and that’s pretty much as slippy as soapy water – but may give that a go too when the CO2 kit arrives. Much prefer the flavoured, or hot/cold, Durex lubes for that…
MrNutt; Wiggle had some in so thought I’d give them a go – I know that some of the STW guys rate them.Posted 9 years agospooky_b329Member
We had to resort to a friends CO2 when we first got UST tyres, we’ve always managed with the trackpump since, assume it was difficult first time as the tyres had been folded up.
We carry a couple of cartridges for rides though in case we feel like repairing a puncture rather than sticking a tube in.
One tip I was given was get the seal using C02, then deflate and reinflate with trackpump as the C02 can cause the sealant to dry/gunk up.Posted 9 years agoMrNuttMember

Bear in mind that if you use sealant in your tyres using CO2 will cause that to degrade quicker than if using air from a pump or compressor, and will need to be replaced sooner than normal.
haha and so it commences! what air for xcfreeride-liteDH? 😆Posted 9 years agospooky_b329Member
You have to find a garage with the old style pumps, the ones around here are the new digital type and they are rubbish, air is restricted and comes in short bursts rather than a constant amount.
You need to push the flat tyre button to get a constant supply of air.Posted 9 years agodoboMember
In all my tyres if you deflate them they pop right out from the bead. So that is a nono.
hmm, that has never ever happened to me with ust rims and ust or non ust tyresPosted 9 years ago
i often deflate mine to top up with wheel milk which i pore through the removable core valves (what a god send)
i use schwalbe, bonty or maxxis tyres fwiw, all really good for using tubeless
