Running standard tires with tubes, no issue...remove the valve stem and install tube and tire

Running standard tires tubeless with sealant...mixed results, burping issues, some tires work better than others. If your trying to save weight, check out "tubeless ready" tires from Specialized, Bontrager, Geax, NoTubes, and Hutchinson. Standard tire casings but Tubeless beads so the burping issues are not a problem.

I have UST rims and have used UST, Tubeless Ready (w/stans) & currently standard tires (w/stans). I have never had an issue with any of the tires. (I weigh 200lbs & run my tires at 33psi) UST tires allowed me to run lower pressure (28psi) because the non-ust tires were to squrmy for me under 30psi. I have never burped but was running into the issue of the tire slipping on the bead. I applied GasgaCinch http://www.gasgacinch.com/ and haven't had a problem since.

Works great with inner tubes, as the tires are designed to be used.

I have just done this - I have Mavic SLR's and running Schwalbe non-ust's tubless.

No loss of air, no burping, all good so far. I am not super agressive though! and all XC.

I had a bit of an issue getting them seated initially but my LBS helped with that and now all good. Dropped 400 grams in the process.

I think as long as the rim is good quality tubelss and you are running a good quality tyre you should be good. Heaps of people are running this set up.

Good luck.

In the 2 cents of my world..

At present I can stand behind ust rims with tubeless or tubeless ready tires. Standard rims with Stans rubber rim strips and standard tires converted. But I don't feel too good about ust rims with standard tires converted.

Obviously tube rims w/ tube tires. And, ust rims with stans rubber rim strips and converted standard tires.

I know one fella who is running Bontrager Mustang tubeless rims w/ converted standard WTB's in rocky terrain and hasn't had a problem. That combo seems to work.

I also run....

Bontrager TLR rims with standard tires + sealant and have had no problems. And a riding buddy has a set of Mavic 819's that he is running with standard tires and sealant without a glitch. The key is a quality tire and the realization that you cannot run stupid low pressures like you can with a UST tire. I weigh in at 210lbs and run between 30 and 35psi with the current setup, depending on the tire that I'm using. I also wouldn't recommend this setup if you ride agressively, i.e. FR, or DH. Go with a full UST set up for these disciplines. I'd also say go UST if you are into the agressive side of AM riding as well. For XC/Trail and light all mountain the ust/standard tire set up can work quite well. I've used Stans converted standard rims and regular tires and am not comfortable with it. Burps were a frequent problem for me with converted tires and wheels. Since building the TLR hoops I haven't had this problem at all.

The bottom line is, in my experience, it's how agressively you ride, and how "big" you go. It's simply a matter of using the proper tool for the job at hand. Most of the problems that I've encountered with UST/Stnadard tire set ups have had three causes, too low of tire pressure, weak tire beads on light "race" tires, and riding too agressively for the set up. I limit my riding on my TLR/Standard set ups to XC/Trail. If I want to get agressive I go with UST tires. And at my weight, tire pressure is always moderate.

So, take into consideration the way you ride. Then determine which setup to go with. If in doubt just go with a UST setup to be safe. Better to be safe and have all your teeth at the end of the ride! :D

What standard tires have been the best in this application in your opinion? I've got Bontrager TLR tires and have been delighted with their TLR tires running tubeless with the bontrager rim strip and stans, but am not satisfied with the availability and selection of tubeless ready tires. I sometimes long to try some standard tires with my rims.

I've had good luck...

with Kenda Nevegal DTC 2.1's, Continental Mountain King 2.2's, Continental Vertical Pro 2.3, Maxxis Advantage 2.2's, and for a commuter tire, oddly enough I run tubeless on my commuter, the Bontrager Select Invert 2.0. The Nevegal and MK are pretty solid and run well in the 30 to 35 psi range, the Advantages are a bit squirmy but don't seem to cause any handling problems unless you drop down to the 2.1 Advantage. The 2.1s have a pretty thin sidewall and squirm quite a bit even at higher pressures. Those are my Favorite tires to run tubeless with TLR or UST rims. My personal preference for the set up is the Bontrager TLR system with regular tires and sealant. The bead seems to seat more firmly with the TLR system than it does with UST rims. May or may not be the case for all UST rims though.

Anyway, those are the ones that I've tried and liked so far. I've been wanting to try some of Panaracers offerings, but gotta wear out a couple of the others first. :thumbsup:

Let me add my recent experience -

Have about 10 rides and two tough XC races on the Gary Fisher Superfly which comes with the Bonty TLR rims and XCX tires. The rims come with a "blue" plastic strip but will not work in a tubeless setup. So I added the Stan's strips and they work perfectly, no burping or loss of much air over days of abuse.

Now for the bad news -

As you might expect from a lightweight XC tire they don't do well in rain, mud, wet rocks etc. But I also have had 3 punctures which the sealant immediately took care of but it appears the casings are too thin ?

I have used Maxxis Crossmark UST for years on my 26" with not a single problem!

Any thoughts on using this standard tire on my TLR rims with the Stans rubber ?

cheers,

Dave

Can't help you much there....

I've never run the cross mark either ust or standard tubeless or otherwise. And I've never owned a 29er. My rule of thumb for even trying a 26" standard tire tubeless is nothing less than 530g weight for XC and nothing less than 600g weight for more agressive riding, and even then I want to handle the tire before trying it. Feel the sidewalls etc. After a while you can get a pretty good "feel" for what a sidewall and carcass should feel like in a standard tire that will work well tubeless. As you noted the ACX Bonty is a bit on the light side.

I'd probably bump those "rule of thumb" weights by about 30 to 50g for a 29er tire and go from there. And then, as I said, it's just a rule of thumb starting point. You can have a tire that fits the weight criteria but still has paper thin sidewalls or carcass construction that is less than optimal for being run tubeless. I've heard of some sucess with running the standard cross mark 29er tubeless, but have never used the tire myself. So I really can't comment on it. All you can do it try it I guess. Hopefully some one else on the board has experience with them and will chime in.

pop?

Squash, when you first air up standard tires with stans on bonty TLR rims (and strips), do you get the loud "pop" as the beads lock into place? I find that this always occurs with tubeless ready tires and it gives me confidence that the bead is seated well. In fact, when I go to change tires, its usually a bit of a bear to unseat the bead with my hands.

I was wondering if the same thing happens with standard tires - including the difficulty unseating the bead when you deflate the tire and try to remove it. If so, that would give me some assurance that the standard tire would work well tubeless with the TLR rim. I'm excited to give some standard tires a try - especially some soft sticky ones.

They sure do...

quite loudly too. The first time I aired up this setup I had to push the pressure to about 60psi before the beads would seat. That in itself made me a bit nervous to start with. Then it scared the living crap out of me when they popped into place. I work at a shop and normally loud pops like that spell trouble, even louder bangs and blown tubes, etc., so I'm a bit sensitive to it. Once seated it is a bit of a bear to unseat the bead when deflated. It takes a good amount of hand pressure to break them loose. And you're right it does inspire a certain amount of confidence. :thumbsup: I haven't found a tire yet that won't pop into place like that. If I ever do I don't think I'll use it, at least not tubeless.

Done a few tough 50 mile type races on the Maxxis Crossmark 29 standard tire on the Bonty TLR + Stan Rubber Strip with no problems.

Man the Bonty XDX TLR stock tires on the Superfly really suck....

What kind of tire pressure you run on Crossmark tubeless?

...those of you that run them. I am about 2 weeks into using them on my 29er with Stans Arch...thanks.
