This worked for me. Ive got Nobby Nic EVO Snakeskin (non UST) and there was no way they were going to seat on my XT wheels. Tube in, pump to 60psi, leave for a day, tube out, Stans in, inflate. I lost a little air from the bead for 5 mins or so but then the Stans sealed the bead and they have held pressure perfectly since.Install a tube as normal - let it sit for a day or to to take shape - then give it a crack..

Have a flick through there mate, obviously ignore anything about rim strips etc. Giving the wheel a good shake is key to tricky setups.
And tube is also a great idea, it allows everything to sit/form nicely before setting up tubeless.

There is an article in the latest MBA that talks about the same problem. Schwalbe tyres not keeping air.
It reported that Schwalbe have identified a release compound that is used in the factory as the reason sealant won't work. They recommend thoroughly cleaning the inside of the tyre with brake cleaner.
The reporter said he tried this it sorted the problem.

Don't drill out your 823s. I take it you're using the tubeless valve stem that came with the rims? You won't be able to use that afterwards...
Personally I've found mounting all tyres on my 823s to be very easy - just did it with a track pump. I try to push down on the tyre, then grab the sides to pull the beads of the tyre to spread them out as much as possible all the way round the rim.
Also found putting the valve directly at the bottom and resting the tyre on the ground (Gently) helps the bead catch...

Hey guys thanks for all the advice what I've done is fitted the tires upto another set of wheels with tubes so that they can get some shape first will give this a go for a good day or so then fit to my Mavic rims with the stans.. I just think the tyres were that out of shape I.e the squished in the box they arrived unlike the perfectly round minions I fitted with ease

well i tried again last night still to no avail.. these are much harder to do then the minions...
what ive done now is thrown in a french valve tube in my mavic 823's and the bead popped as i was pumping it up so hopefully thats good sign, i noticed when i was trying to fill it up that the air was coming out right near the valve so im going to try a few more of the tips in the video like patting down the tyre and using soapy water, (i dont normally do this with the minions)

I run 823s and I've just stuck a set of Schwalbe's on. At first it wouldn't seal for around ten minutes so I put more sealant in (around 50ml each tyre) and it has now set just fine.
When you are taking the valve in and out you need to make sure that you don't lose the O ring that sits under the screw on cap on the outside of the rim. You also need to make sure that when you do this up firmly by hand that the rubber part on the inside of the rim sits snug in the rim. Put your sealant in, pump it up with an air compressor until it pops all round and then use a floor pump to put 60psi in it. Spend ten minutes rolling your wheel on it's side and upside down and any which way that will see the sealant sit on the bead.
I need to check my pressures each time I ride but it only loses around 4 psi over a week or two. The pressure doesn't drop when I'm riding so I have full confidence in the tyre and the setup.

Are you removing the valve core? With most UST tires I've used (mainly kenda) I've just popped them on and they've been fine but most normal tires I've had to remove the valve core to get the tire to seat.
Pull the valve core out, squirt a crap load of sealant in there (Like 3 capfuls) and pump like crazy to about 60psi. That should seat the tire, then put your valve core back in and re-inflate to 60-70psi and roll and shake that wheel. Then leave it on it's side for a while and periodically shake it and flip it. Then leave the wheel in a bike upside down so that you can spin it once in a while. Has worked for me every time (goes in seach of wood!)
Also, have you tried rotating the tire? Ie- is it the same point on the tire thats not sealing or the same point on the rim? If you shuffle your tire around 90degrees and try again you'll be able to tell if it's that point on the tire that isn't seating/sealing or if it's an issue with the area around the valve on your rim. Your efforts may have been misguided

I'm running non UST Muddy Mary's tubeless on my Crank Bros Opium wheels (tubeless), using Stans sealant. Originally had sealing issues like you're saying with another sealant, but scrapped that and put Stans in and that solved it. Might have something to do with the bead of the tires not being well suited to the 823's. Or just a technique issue as others are saying.
Only issue I'm having is a little bit of burping that occurs on tracks with hard off cambers. So i think I may need to chuck a rim strip in, as I don't already have one. Opinions?

well i got the muddy mary working on the front,
I chucked a tube in and let it pop to the bead then removed the tube, put stans in and soapy water and instantly went up..
With the rear im trying to fit a wicked will and having a issues i tried getting tube in the rim but each time i tried to do that i pinched anyway the tyre has more shape so gave it a go, same deal stans and soapy water the tire still has some kinks in it but not that bad.. anyway wouldnt bead at all trying rotating the tyre and and moving around just wont sit will.. Not sure if the tire was to skinny its a 2.35 but its like a 2.5 minion... will have another go tomorrow at it..

Tyres too tight
I just tried converting my wheels to tubeless. Got a stans conversion kit and some Schwalbe UST tyres (racing ralph and nobby nic.)
It took me ages to get the tyre on my wheel (DT swiss 420SL rims) and then I couldn't get it back off. Took it to the bike shop and he said it was the tightest and most incompatible match he'd seen - he also couldn't get the tyre off. Spent hours working on it and 4 broken tyre levers later finally got it off. I can't seem to find any info on the net about certain rims not fitting certain tyres so a bit scared as to what to buy next. Was getting pretty excited about using the Schwalbe's until now. Any advice?

Dont try and mount them on a Stans rim as they are tighter again. I found the dt swiss rims far easier to mount the same type of tyre...

mtbr is full of posters compaining about the very same thing. So is Stan's forum. The 2011 tubeless ready Schwalbes are a nightmare to mount on Stans rims.
Thats going to happen to any tyre when you do that!
I have been using Rocket Rons since 2009, fave tyre ever.
One issue at Mt Buller in a race, hit a rock at the wrong angle, pierced tyre, but that was just random bad luck on my part.
Happy camper here.
