Tubed tires on UST rims

[plojaa]

Got a set of UST (mavic) wheels recently. Set also takes tubed tires. I've trolled the forums for info / read the mavic docs etc. Seems tubeless tires require alot of work vs tubed....

Nonetheless....what are peoples experiences w/ running Tubed tires on UST rims? The biggest issue I have found is getting rid of the tire wobble - side to side and up/down.

Thanks

I've had the same set of tubeless tires on a pair of Mavic rims for two years without one problem. Don't give up on tubeless.

I had a pinhole leak that didn't seal with slime, so I put a tube in it. The tires were incredibly hard to seat. I had a flat on a WF night right and Jabberwocky grabbed my wheel out of my hands before I could try myself (I may be mechanically inept, but I can fix a flat/change a tube :rolleyes: ). It took him 20 minutes fighting to get the tire on.

Loren (mechanic at the Bike Lane) said the trick is to get the rims to go in the central, inner groove. I have Maavic 819s.

But I went back to my UST and used Stan's. I've had no trouble at all.

I had no "wobble" or any problems with the tube. Though I guess I should point out, I had won a set of tires at the MORE winter party so I had a pair of non-UST tires laying around. I didn't have the tube in the UST tires, just on the UST/non-UST rims.

Have a set of bontrager race x lite wheels. Used tubed and tubeless tires on there. Didn't have one problem. You just have to make sure to get enough stanz or whatever sealant you use in the tubed tires for them to seat easily. I've heard there is a list of tubed tires on the stanz website that are more difficult than others to seat.

I have one rim on my singlespeed that is a UST rim, but have run it with tubes since I got the wheel about a year and a half ago. I have had no problem running tubes in a rim designed to be run tubeless. So, you should have no problems.

Depending on the rims, I think UST rims can be a little more difficult to mount tubed tires on. I had some problems a few weeks ago, trying to mount tubed tires on my Mavic UST rims. I could NOT, for the life of me, get that freakin' tire on. I finally ended up taking out the tube, throwing some Stans in there, and the tire went on super easy.

My two main bikes have Mavic Crossmax tubeless wheels and I run both tubed and tubeless depending on what trails I'm riding.

On my freeride (heavier) bike I run bigger tires and run tubes. The bigger the tire the harder to get seated right to get rid of wobble. I am running 2.5's on the Crossmax XL's with tubes. (For more DH type riding.)

On my other (lighter) bike I have Crossmax SL's and run tubeless most of the time. They do leak - depending on the tire. I generally use Hutchisons and while the traction is awesome, they tend to have slow leaks. At times I can get them to not leak at all. Currently my front has held air for two weeks. I got frustrated with the rear and put a new tire and a tube on it recently.

I have mavic crossmax ust rims.

I mostly run UST tires and love it. Without the Stan liquid they tended to slowly deflate but with Stan's they keep their nominal pressure for months. It also protects against most punctures. I would never mount my UST without the Stan's anymore.

Some UST tires are a nightmare to get on the rims: IRC Seracs were terrible. Warming them before putting them on seemed to help though. I guess the rubber stretches more when warm. Hutchinson Python and Panaracer FireXCpro are super easy to put on.

Non UST tires (tubed tires) were easy to get on the rim but hard to seat properly. You need to inflate them at about 15 psi then push and pull to make sure the bead is in the proper place. The narrower the tires the worst it seems to be. I had to go to the bike shop mechanics to help me put 1.5 slicks on. He use some kind of flat pincers to tug at the tire to place it correctly.

Using tubes in a UST rim is a SIN! You get the weight and financial penalty without any benefits! Since you already have the tubeless rim give the tubeless tires a try (with stan's liquid inside). It delivered me from pinch flats and 90% of puncture flats (sometimes the hole is to big even for stan) plus it gives my hardtail a smoother ride cause I can ride at 30 PSI instead of the 35-38 I had to with tubes to avoid pinch flats.

Using tubes in a UST rim is a SIN!

I agree, the only reason I was trying to do it, was because my UST rims were all messed up... The soft plastic stuff inside the rim had been bent/dinged, causing my tires to no longer hold air without lots of Stans. I was hesitant to use Stans on my brand new Nevegals because the last ones I had with Stans in them got bubbles in the rubber and eventually came apart. Bad times.

A thought: I have specialized fast trak tires 2.2 - they are regular tubed tires. I know you say non ust tires above but is this really a NO NO ie should I be using Tubeless tires regardless of tube usage ..... or are regular tires w/ tubes ok - Sinners beware.

Sounds like tubeless tires are messy to mount but are they really? Is this a good poll question...tubes vs tubeless.

Any idea what pros run?

If you are going to use tubes, regardless of whether your rims are meant to be tubeless or not, you do not need UST tires, you can use regular tires. Tires designed to be tubeless are typically heavier, so if you are using tubes with those tires you are going to pay a weight penalty. As for running tires tubeless, and which type of tire to run, things I have seen recommend using UST tires, but I know several people who run regular tires without tubes and have no problems.

He is right and that's the way to have the tire seated right. Also, try to start mounting at the position opposite to the valve stem. I found 819 is actually very easy to work with.

If you already have a set of tires you like, try them on with tubes. It doesn't make sense to spend 100$ for a pair of new tires if you already have some.
Most of them will work fine, you just have to make sure that they are seated properly. You'll just need to go to church more often to wash your sins away and promise the bike god that your next set will be UST:)

As far as messiness goes, there are a few things you must know before putting a tubeless tire on but once you are used to it, I believe it is as simple as a tire with a tube. Plus, you don't run the risk of pinching a tube while putting it on. And the best part is: it is likely the last time you will have to do it until your tire is worn out. (or until the stan's dries up in 3-6 months)

Here is how I put on my tubeless tires:
-it helps to wet the beads with soapy water if it is hard to put on but not generally necessary.
-Tire needs to be in center of rim to help put it on (finishing with the valve)
-Once the second bead is almost all the way in, pour the stan juice in and rotate the tire 180 so the juice is at the bottom and the opening is on top. This should eliminate spillage
-Use a high volume foor pump or compressor and inflate quickly to max pressure. Make sure the tire pops and is evenly seated. You might need to wiggle it to help it settle in place.
-Deflate to a comfortable 30-32 psi

Thanks for all the advice from all. I took Jeep's advice to not spend $100 on tires w/o giving it the old college try

It worked. I read this stuff over and over and reseated the tire beads into the center of the rim deflated. I then took it up to 70psi and low and behold both tires popped a few times and the wobble is gone...took it back down after that. Most of the tire was in place...just a few areas that wouldn't. I think the extra pressure I put in them forced the tires to seat themselves. Thanks again

BTW...these are crossmax enduro rims I got off sierra trading post....anyone have these?
