I have recently bought some 650 Stans Arch Ex no tubes wheels, and bought some tyres to put on - got the sealant and im struglling to get the tyre to go onto the rim true - i seem to be pumping the hell out of the tyre to get it up but then it doesnt sit properly - il be honest im using push down stand up pump thing which i thought would push enough air in, but im absoluley knackered, im thinking i need a new pump. Or am i doing something wrong whilst trying to fit?
This is a perennial question with tubeless tyres and I fully sympathise with your plight.
For what it's worth here's my two penneth, in no particular order:
- use plenty of soapy water to help get the bead to pop on
- add plenty of sealant and make sure some is all over the bead (this helps it to properly seal quicker once it's seated)
- forget using a garage forecourt air compressor, didn't work for me
- make sure the bead is either side of the air valve and tucked in a far as possible. This is usually the hardest bit to close up
- make a coke bottle air reservoir, Google it, it's the only thing I've had success with
- a small air compressor to help fill the coke bottle is a nice to have but not necessarily a must
- be patient
- ignore anyone that says "oh it's easy, I've never had a probelm", they're lying
Good luck.
Just get to a compressor for your sex without condom experience.

My Stans rims used to go up with a track pump or the occasional Co2 cartridge. Have a look here âž¡

I now have a Sram Rail 50 wheelset and all the tyres i have tried require a compressor to seat them. Just bought one of these so I don't have to bother my Lbs.

it's not a conti tyre is it?
I'm using Conti's and the first one wasn't too bad, the second one was a bit of a mare. The coke bottle worked in the end.
Get them seated using an inner tube (possibly leave overnight), then deflate and unseat one side, remove tube and install tubeless valve. Seat tyre using pump, hopefully. If successful then unseat a little bit so you can add sealant. Seat again.
I did this with WTB TCS tyres and rims. One worked like a charm using a standard track pump. The other needed a co2 inflator to seat.
My Trigger came Tubed with Stans and Dampfs. Converting to tubeless took 30 minutes for the first as it was my first time. The second took under five minutes when I got my head around how much soapy water to use. I actually rubbed a bit of soap on the tyre bead too...
All you people using loads of soapy water - doesn't it get into the wheel and slosh around making the sealant not work?
I generally find a dash of sealant rubbed around the bead to do the job.

When I say 'plenty' I mean a liberal application with a brush on the bead and rim not filling the tyre with it. The sealant sloshes around, at least for a little while, anyway.

This, helps the bead locate, and gives a bit of seal as you pump. Single most important step I reckon.
I need to take a break from my screen, read this topic as 1st-time-lubeless. 😯
Using soapy water around the bead works ok, but I've stopped faffing with it. It sometimes worked, and maybe I was doing it wrong, but I found that if it did finally seal, the soapy mixture interfered with the tyre sealant (plus it just made the whole process messier).
I think the tyre fitting industry use something called Tyre Lube or Tyre Grease, which works by letting the tyre pop onto the rim easily and help form an airtight seal.
My favoured approach (with Stans rims and pretty much any Maxxis TR tyre)
1. Pop everything in place, unscrew valve inner. As said above, make sure the bead is properly on the rim, especially around the valve. The tyre should be pretty hard to get on, so if it pops on without much of a fight, I now tend to get worried.
2. Inflate with track pump
3. If that fails, get ghetto tubeless inflator on the case (brilliant bodge and costs pence to make)
4. Only once I have got the tyre up to around 35-40psi and am sure its popped on, do I let the air out
5. Stick sealant in, replace valve inner and inflate until its reseated
6. Give the wheel a lot of shakes, spins and ideally head out for a quick ride
E-13 trs 5mins per wheel
mavic 719 with stans kit 10 mins per wheel
mavic 819 a real pain in the tush
used a track pump on all with different tyres but all tubless ready.As mentioned before if the tyre bead doesn't seat,spot where the jizz is coming out and leave that part at bottom for 10mins,then try again.
this is really hard, suffering with failure at the moment- tried the bottle thing, didnt work - probably material base - would a petrol garage air pump do the job?
Try a ratchet strap around the tyre to push the bead into the rim.
I have never used the soapy water trick I leave the wheel & tire in full sun to warm up and co2 system (not much good in the winter)
Done Done Done! Finally! Went to the garage no good, wouldnt work with the shrader valave adapter thingy and managed to break off the core (great start), ended up using a double barrelled footpump hands on the ceiling jobby and pumped the heck out of it and listen to it pop! On with sealant in, even got a good way to inject the sealant into the tyre, remove the core then use some coaxial cable, pull the inner out pefect fit for schrader and 1pt bottle 🙂
My first attempt at going tubeless recently was a doddle in comparison.
I'm using Stans Flow rims in 29er flavour, Spez Purgatory Control Tyres, 1"Gorilla Tape as rim tape and some Mavic Tubeless valves that I acquired years ago.
To lube the tyre beads I got bar of soap(read somewhere that it works better than washing up liquid) and mixed with some warm water smeared it on the sidewall with a small sponge, inflated with a track pump and both tyres went up first try.
Left overnight to settle the beads and then next day put sealant in via the valve(Using OKO magic milk)they had of course lost air overnight but once the sealant was in when straight back up again with the track pump.
Maybe I just struck lucky on a good combo.
Going to have to contradict you poisonspider I'm afraid.
Last week I went tubeless. Took ten minutes easy work each wheel.
I was using Bonty TLR wheels, Bonty TLR tyres and valves etc. But, it was simple...and I've ridden on them since and haven't lost ant pressure yet either..
