I’m surprised that there isn’t more action on this thread. So I used the compressor to seat the beads but there was another hole I missed patching. I patched that one and thought maybe that was the issue with the beads not seating but still had to use the compressor to seat the second time. It’s holding fine now. I feel there is still plenty of life on the tread but the beads do seem to be breaking down.
I am going to try going back to tubed GP 4000 II next but I think I may also try Schwalbe pro ones tubeless down the road. So if you have tried these on Mavic UST rims, please let us know about your experiences.

Below is the review for the Mavic UST tires. Bicycle Rolling Resistance rated them 5/5 Highly Recommended
Mavic Yksion UST tires review link
For comparison, below is the link for the review of the Mavic non UST regular clincher tires. Bicycle Rolling Resistance rated them as 2/5 Not Recommended
Mavic Yksion Elite clincher tires review link
As mentioned, looks like on performance alone, Mavic has a winner with these UST tires (and with their tubeless system). However, it is a concern of mine that they appear to be the only ones making UST tires. In a holding pattern until more reviews trickle in for this tubeless system.

For those of you running these tires: Do the tires have tire wear indicators? (like GP4000SIIs and Michelin Power Competition tires).

Been following this thread and sad to see it die down. I am really interested in this UST system. It may be what pushes me to the tubeless side but I like to read real user's long term reviews, not marketing videos or first impressions. Anyways, your comment that they are comparable to the Continental GP4000SII's appears to be proven in the lab as per the latest tests from the Bicycle Rolling Resistance website. Very competitive with Continental GP4000SIIs, Schwalbe Pro One, and MIchelin Power Competitions. Looks like Mavic has a winner here (their previous regular clincher tires are quite dissapointing as per many people's reviews as well as the bicycle rolling resistance website).

If there was, I wore right through them without noticing...

Just bought a pair of the Mavic Pro Carbon and the UST is sweet. Love the tubeless! I am about 6'2" and just under 220lbs and I am running 70 in the front and 75 in the back. As compared to 105 / 110 on tubed wheels. Crappy pic, but these wheels and UST in General is the real deal. Also, the tires seem to be wearing well. Have about 300ish miles so far and not noticing anything out of the ordinary.

What did you end up doing? Did you go back to tubed GP4000 SII? If so how easy/hard was it to mount the tires in these UST rims? Alternatively, if you moved over to Schwalbe Pro Ones, what has been your experience in relation to the Yksion UST tires with regards to feel on the road, ease of install , etc. Tryring to learn as much as possible about this and tubeless in particular before I decide to take the plunge or not.

Thanks for your reply. Still interested in this UST system.

I wanted to try the Schwalbe tires but I rather not be the guinea pig. I would like to hear some one that's already tried them and had success. I even tried emailing Schwalbe tech support about mounting them on Mavic UST wheels, but they never responded to that's not encouraging. Furthermore, I have a set of 40C Kenda Happy medium gravel bike tires I use on my other (cross) bike and they are supposed to be tubeless ready. So I tried mounting them on the Mavic UST wheels just to test out. They went on nice and easy and I was able to use the floor pump and got pressure up to 60# before I stopped. However despite hearing the pop sound like they had properly seated the beads, they never held air and loudly leaked down to no pressure rather quickly (minute or so). Now I tested them without sealant, but the Yksion's will seat and hold pressure just fine without sealant. So this had me worried about in general using 3rd party tires and if they will properly hold air or not in the UST wheels.
In general, the Yksions are great tires, but I would really like to get more life out of them. Its nothing for me to get 5000 miles on GP4000's and I can get them online for half the price of the Yksions. This makes the cost of ownership of the Yksions' over 4 times higher than the gp4000's.

Yksion tear on sidewall after 100 miles
I have ordered a set of Mavic Ksyrium Elite USD wheels and they come with WST Yksion Pro UST ties Tubless, Does anyone have any experience with these tires. I know they are free and come with the wheels, I was just wanting to know what to expect. I have been running Con GP4000S2 for years with nothing but great service and great millage easy getting 5000 miles on rear tire. Thanks
I started using a Mavic Comete Wheelset with Yksion PRO UST Tubeless tires and on my 4th ride I got a tear on the sidewall near the rim that does not seal.
I am no expert but I think the tire is unusable...
I also did not find a local shop with that tire, so I had to order a replacement online...
So my my bike is on the bench right now

This is a compatibility problem that hadn't crossed my mind and it really blows. No spare wheelset laying around?

Done a few on the side wall and if they are small like 1/4" or so I don't mind. Now if yours is a larger tear kind of thing, I might just skip trying to repair it.

Will try to patch the tire
You can probably just inflate the tire as much as possible removed from the bike, Then turn the wheel on the side of the hole and give it a few spins. It might just seal back up. Remember the sealant, unless you put a crap load in, wont have enough level to cover the sidewalls. You know you can just put a tube in the tire and get it off the bench right?
I was told I can patch the tire, just like I patch tubes...
I believe the particular Mavic Comete wheels I got, cannot be converted to a tube setup... but I am not 100% sure

There are no issues with putting inner tubes in with Comete UST wheels. Just remove the tubeless valve stem and slap the tube in like normal.

Tube valve lenght for Mavic Comete, right PSI
I have decided to install tubes on these wheels.
Since the wheel is 60mm deep, a tube with an 800 valve lenght should work, Right?
Also, 80 psi is recommended for the tubeless setup, when I install a tube, should I continue to use 80mm or higher as in the standard tube clinchers (approx 120psi)?
Thank you for helping.

80mm should work just fine depending on if your pump if finicky however. I wouldn’t ride higher than 90# with tubes unless
you a big clides kind of guy

I've got 800-1000 miles on them. Bike needed a new wheelset, GP4000 rider previously.
The newer 2017 Yksion UST are different from old, reportedly using a new ElevenStorm compound by Hutchison.
I like them. They ride real plush with the tubeless setup. I've had them in the mountains at 45mph, and in the separately in the rain. Confident handling all around. If this keeps up for another ~2,000 miles, I'll be buying again.

Bumping to ask whether people who bought the Ksyrium Elites received QR adapters as well? Mavic's site says the wheelset comes with them, but I don't see the adapters mentioned on various retailer sites like Competitive Cyclist.

So I wanted to give an update on my Yksion USTs. I nailed a chunk of concrete about 2 inches high in the road at 20mph and it pinched a hole in the side wall of my front tire about 2 months ago. The hole was above the level of sealant so it didn't re seal until I tilted the tire on its side and gave it a spin to the sealant could get to the hole. The sealant held pretty well but blew out a couple of times where I had turn the wheel on its side again to reseal. That was in the week or so after the puncture but I haven't had any more issues with it since.
Yesterday on the final 4 blocks of my ride, I must have ran over some glass and the rear tire started spraying sealant all over but sealed itself after a block. I rode home and decided I was going to try a patch kit from Performance like the Hutchinson tubeless tire patch, but like 4 times cheaper. I guess I just have trust issues with the sealant and not wanting to have to deal with it on a long ride. When I went to reseat the tire bead, I couldn't get it to seat. I tried with sealant already in the tire and without but I could not get it to reseat. I even tried a CO2 but it didn't seat. Now when these were new, they seated with one or two strokes of the floor pump: super easy. I wonder if the tire isn't just worn out and has lost its rigidity and wont seat right.
I have a compressor at home, but I don't have a presta fiting for it. I am going to pick up a schrader to presta adapter today to give that a shot.
So my question for anyone using these Yksion UST tires is how much life are you getting out of these? I currently have 1600 miles in mine. They have a little life left but they do seem to be wearing faster than my GP4000 II's. OK a lot faster. Prices on these Yksions are hard to find less than full retail so its like $80 per tire where I could get the GP4000 II for more like $35 a tire and get twice the life. Plus you need to top off the sealant every few months so prices of tubes kind of gets nullified by the price of sealant.
Have any one of you used a different tubeless tire with their Mavic UST rims? I see Giant now has Gavia UST tires set to the same Mavic UST standard but they are $80 for the high thread count and $50 for the lower thread count. I would like to stay tubeless but it would be great to get some better wear life out of them. Also I am pretty sure the GP4000's would have laughed at the same patch of glass that took out the Yksions yesterday so some better puncture protection would be nice too.

I had a similar problem re-sealing IRC RBCC's on my wife's bike after a blown rim tape. A soap spray or a rim before mounting tire did magic on it.
