Who is running normal Maxxis folding tyres, tubless?
Just got my new 29er wheelset. Hope hubs / No Tube Arch rims. Want to run some normal Maxxis folding tyres, tubless.
Has anyone had any problems doing this? Tyres "burping of rims" what sort of pressures should be run.
Cheers

Have done on 26er UST rims. Ran fine, but did burp off the front once... forgot to check the pressure. The rear was at 17psi, so I'd guess the front was similar. On the upside, I learned how to change out the valve and pop a tube in.
Yep, have done with ardents and currently with Aspen exceptions. As said above keep an eye on the pressures as I've had the front roll off the rim a couple of times when running pressures down around 25psi. I've got XT UST wheels FWIW.
with either crossmark USTs or Ikon's on Mavic 819 UST rims. In NZ recently I was running the Ikon from down at 20psi for a while and it was fine although it got too vague as the pace hotted up so I added more air.
I'm running the 29" Ignitor Evo tubeless. At a guess at 26-28 psi.
Just bought some new crossmarks and realised they are UST tires. Could be stupid questions but these are ok to a) put on non-tubeless rims?and b) put tubes in them?
If u cant return them they will be fine, non UST are cheaper and light
I run non ust tyres as ust on all my bikes with no issues.
Answers to your specific questions are:
a) Yes
b) Yes.
Because of the weight issue, you're best off to stick with non UST tyre, unless you need the stronger sidewalls (eg my tyres often wear out on the sidewalls or fail just above the bead because I'm a tad on the heavy side. A UST XC tyre is a better option for me than going to a DH tyre for the sort of riding I do).
I ran non-UST folding 26in Crossmarks on non-UST rims in a ghetto tubeless set up until they were had it with no flats, burps or any problems. Kept pressures a little higher than with UST tryes but they were good.
UST tyres corner better at low pressure imo. the tyrewall flex in non ust versions makes them feel horrible in corners untill you are in the mid twenties pressure wise in the front. if you have ust rims, i'd run ust's so you can use the low pressure option with them - if not ust rim, then the extra bead is superfluous I think, so you only get the advantage of the stiffer sidewall.
I've found that the normal (non-UST) Maxxis tyres can be a major challenge to mount on Mavic rims (again non-UST) with the Stan's kit. I usually get the "Exception" version of the tyres for the lowest weight but you'll find that the UST version of tyres are much easier to get sealed up.
These are the Maxxis tyres I've tried to set up tubeless:
Aspen - Couldn't seal even with the servo air compressor.
Crossmark - ditto.
Ranchero - surprisingly easy with a floor pump.
Larsen TT - managed with a floor pump but required some furious work.
The tyres that I've been able to set up tubeless have been fine once on - no issues with burping, whatsoever.
I did have some issues with the valve coming off the Stan's rim strip, but that not really a problem related to they tyres themselves. The only maintence is that you have to check your pressures regularly (weekly) as you can get slow leaks.
Also, as mentioned earlier, if you're prone to getting sidewall slashes - then the UST tyres would be a better option due to the thicker sidewalls. I've killed a couple of non-UST tyres this way - although if the slash is smallish you can try to put a patch on the inside of the tyre to get more mileage from them, but only for leisurely riding. I wouldn't put too much trust in it for hard & aggresive riding.....
Going to go tubeless now seeing as I have the tires already. The friendly guys at my LBS said they will put them on for me - for a fee of course, but at least I can be happy that they will work (non tubeless rims).
It's actually cheaper getting the LBS to do it than buying Stan's kit - although I appreciate Stans does 8 tires or so I am told.
Remember that these are lighter race oriented tyres which essentially means that they have less rubber where they can - the sidewalls. I've used these and whilst they are good as a race set if you're trying to save grams they aren't so great with Sydney sandstone, they wear easily which means tears. Yes, yes, pick your lines, etc., etc. but we all pick a bad one every now and then and with the Exceptions that can be game over. If you're not so concerned about the added weight definitely go for the UST specific versions - ghetto tubeless with a little sealant will then do the trick.
I've managed to get the non exceptional versions of the Aspen, Crossmark and Ignitor to run tubeless BUT they proved to be too fragile for the places I like to ride/ kind of riding I do.
I split the sidewall gave out on the Crossmark in a big way going down a hill without hitting anything of note and the Aspen went quietly.
The Ignitor lasted better but still on;y lasted a month or so.
I found the exceptional Aspen just wouldn't hold air, even with gunk.
On the other hand the proper UST Maxxis' have proved bulletproof, although they are a bit heavy. I run them on my general trail/freeride bike.
Light, fast & ust capable try the Specialized 2Bliss range, notably the Captain & new Renegade.
Lighter proper usts go for Schwalbe.
The EXO models offer extra protection and sidewall without being as full on or heavy as UST. I run a EXO Ikon (replaced UST Crossmark) tubeless with no problems to date. To put it in persepctive relative weights on a crossmark (they dont do a UST Ikon) are
std Crossmark: 545g
EXO Crossmark:545g
UST Crossmark: 720g
Just be aware that with the Schwalbe UST you pay the usual price for light weight. I had one die at the end of Long trail from a rock strike on the sidewall.
It'd been showing signs for a couple of weeks and I thought, "arrh, I'll get around tuit" (planning to apply a patch internally) and of course the puncture fairy came to visit at the farthest possible point from civilisation! Probably he thought I'd been having too much fun bombing off the water bars and getting air, and thought he'd bring me back to earth
(at least this time with no thud)
The tread was looking pretty gouged on the side lugs, so I binned it when I got home and chucked a new one on.
For the stuff I ride I'm happy to take the risk, but for locations with sharper rocks I'd go back to Maxxis UST.
sidewalls area a little thin. After a while the goo starts to ooze through
Standard Crossmarks over the years have varied a lot in weight. When I last got around to chucking them on the scales there was a 80gm difference on the standard crossmarks in my shed.
