I was able to mount my High Roller LUST tires just fine and sealed great (no leakage). I even heard the nice "pop" sound when the bead sat. The issue I'm having is that they mounted unevenly and show wobble when spinning the wheel.

I'm using WTB Speed Dsic rims with a Stan's rim liner.

Should I be worried that these things are gonna grenade under me? :confused:

Use some kind of lube on the bead before inflating?

Make the sure the bead is completed seated all the way around on both sides of the tire- it sounds like that's the problem. Most of the time when I mount Maxxis UST tires, it takes several "pops" until the bead is seated all the way around on both sides.

And, of course, soapy water is crucial, as the others have mentioned.

Is it *badly* uneven, or just a little? It's not a big deal if it's just a little.
Just a little... it spins like a have a slightly bent rim (which is not the case). It is seated just fine (heard the pops and what-not). These are the first UST tires I've used, I've mounted non-UST tires with Stan's without any problems and I've also never experienced this wierd uneven thing going on.

I guess I should just ride them and hope for the best.

Do a quick visual inspection of the bead all around the tire on both sides. Make sure the same amount of rubber is sticking out from the bead all around. If you see a spot that is lower than the rest, then you need to re-seat the tire onto the rim. Or you could try to grab that section of tire and gently pry it out with your hands, but it's sometimes difficult or impossible. If the tire is evenly seated all around the rim, then you probably have a warped casing that will either ride its self out or do no damage (as long as it's not hitting the frame).

Thanks. I tried to even it out, but it was insanely difficult. I even re-mounted them a couple of times and the same thing happened in the same spot(s). I even tried fiddling with the rim strip to make it even all the way around and there STILL are low and high spots.

I don't care about the unevenness - I'm more concerned about safety.

Not sure if this is any help but I got some maxxis ust tires put on at my lbs (among other things just incase you think I would take my bike just to get tyres put on!) The guy inflated them to 60psi and said I should ride for a little while at that pressure to help seat all the beading. Might be worth a try?

Try a high pressure inflation, but riding them won't help it seat. If you can't get it to seat at 60psi, you might need some help from the dreaded tire pliers. Just be careful, those tires at high pressure are really really loud when they blow.

I don't feel good about riding tires that aren't seated properly, and I don't recommend anyone else do it.

They seemed seated. I could even hear them "pop" into the seat. They just have high and low spots.

Well, yeah, they pop, but did you visually check the bead all the way around to see if it's even? Like I said, they might just have a natural warp in them and be perfectly safe to ride but if you didn't check the seating, then you won't know.

I have the same issue but I mounted mine with a tube. I am away on holiday for all of January so I dont want to put Stans in there now. I also had a low spot on my front and didnt mount the rear. I used soap and inflated to 50psi or so, still a low spot. What I want to know is
1. does the tube stop the tyre from seating into the grove that the UST tyre seems to have
2. are these tyres really small volume or is it because the tube is stopping it form seating into groove as per 1. My 2.5 ust High Roller is smaller than any of my 2.35 tyres, by a long way.
I have removed the tyre for now and hope that when I get back and mount it ghetto tubless it will seat properly and have more volume.

I had the same exact situation happen to me (last week) using the Stan's rim strip and a set of Speed Disc wheels/rims. The tires were Kenda Dread Tread and had mounted perfectly on a set of Rhyno lites/Stan's rim strips…they are super smooth and even. I bought another brand new pair of the Kenda DT and tried to mount them on the Speed Disc/Stan's rim strip and it was totally uneven (both wheels) no matter what I did, soapy water on bead, inflate to 50 lbs., take off and re-mount tire and rim strip etc. nothing worked. I then tried a new Kenda Kharisma on the front and the same thing happened. I thought that riding on the wheels would even them out … NOT! The bike was un rideable on pavement. Out of frustration I took out the rim strips and did a ghetto tubeless conversion and it worked perfectly fine. I've used the Stan's rim strip with other wheels and it has worked with no problems, but I'm going to stick with the ghetto tubeless conversions. I can't justify spending the extra money for the rim strip when I can just use a much cheaper tube and get the same or better results. There have been other posts about this same problem in the past about the Speed Disc rim and Stan's rim strip incompatibility.

THANK YOU! I was thinking this, but this totally confirmed the issue. Looks like I'm going ghetto!

Sometimes it is the tire :(
I have a HR LUST, or had I guess since I gave it to a friend, that had something wrong with the construction. The tread did not spin true to the casing. So it would mount up great, evenly beaded. But the tire would have about 1/8-1/4in of visual wobble.

I have also had some Specialized and Schwalbe tires in the past with the same issue. The Specialized was very annoying on the road, but not perceptible on dirt. The HR was worse, but even on the road you couldn't feel it.

It is up to you how you want to handle it, but personally I would take it back for an exchange. There is no way to fix a wobbly tire. You either deal with it or you don't.

i had to put my regular high rollers to 80 psi to get them too set right, and that was with chain lub on the rim and the tire. i have the same rims so it may just be the rims.

And you still have your hands? Natural selection is failing us in so many ways here.

The irony in all this is I tried to do the right thing by using real UST tires rather than going non-UST (which I've had great luck with). Oh well... I'm going to ride them to see how bad they feel. Like I said, as long as they don't explode underneath me, I'm generally okay with it.

But that inflating to 80psi action is skerry!
