In any case- even if a UST tire blew off, your tire is unreliable at that point. This really has nothing to do with UST, tubeless ready, or folding bead and more to do with the type of failure preceding your trying to re-use the tire.

Regular tires do not. the special bead locks onto the rim (which also has to be tlr, tubeless, ust, etc.) C Cow

What is the difference between a regular tire and a Tubeless Ready tire? I've just suffered an experience with a 29r Spec S-Works Fasttrack LK 2bliss ready tire. The tire mounted up tubeless nicely, when new. Due to a rim failure, the tire blew off at speed, fortunately in a straight away. I am not able to get the tire to mount tubeless now. When new, the tire was a little tighter on the rim before inflation. Nows it'll flap in a breeze, hanging from the rim. This reminds of another experience I had once with a non-UST tire and rim combo, that blew off from a sideways landing. The tire would not seat tubeless again. It seems to me that once a non- UST tire blows off, it stretches at the bead, and is or is near impossible to re-seat. The UST tires that I have dealt with are tight when mounted initially, and on consecutive remounts. So, back to my original question, what is the difference between a regular tire and a Tubeless Ready tire? Are we paying for something we are not getting? Is it like the "Digital Ready" stereo speakers of the early 80's, in that it means nothing but marketing hype? Thanks for any insight.

Now the lower pressure is fine for traction but the big hit comes in the sidewall damage. Once you start running low pressures, the tube type tires run tubless and most of the Tubeless ready type tires dont have strong enough sidewalls unless you're riding buff singletrack xc, once you start in on rocks the sidewalls rip. UST sidewalls are thicker because of the air tight layer and so the sidewalls hold up better. alot of the new tubeless and tlr tires are coming out with an extra layer of kevlar which I hope will address this problem. as it stands now my "tubeless" tires last maybe 2 months in the rear as I see it , the only real advantage to going tubeless is traction, which is achived by running lower pressure, you may be able to save a little weight also but it depends on the tires and setup used.

The other reason why tubeless ready tires are taking off so big is inventory: Instead of stocking each tire in each size in UST and tubed versions now a store can simply sell any tire to any customer, regardless of whether they want to run tubes or not. As a tubelss rider I love that because it means manufacturers will produce all their sizes and models in a version I can use and my LBS is will have many more tires in stock for me to choose from.

The XDX is the new name of the Dry X. Same tire, new name. Bontrager felt that the "dry" in the name was limiting sales. Actually, this tire is a great all rounder. New 29"er stuff from Bontrager should include the long awaited and talked about Mud X, the new Team XR ( A "low tread" version of the regular XR, if you will.) and a rumored big, meaty, aggressive tire. Possibly based on something from the Big Earl series. John from Cape Town: Actually a Jones XR is now available as a tubeless ready tire, just so you know. The XDX is the new name of the Dry X.

I initially ran the Jones XR front and rear on Stans ZTR 355 rims with tape only and Stans sealant, They were fantastic but on the third set and two semi-aborted races with shredded sidewalls I went over to Hutchie UST Pythons. There also seems to be an XDX? but no info on their website, any ideas as to where they are going? Ted, what is in the Bontrager pipeline?

The fact that savvy riders put a bit of Stan's goop in UST tires tells us something about how necessary full UST certification is. I can use a standard tire, pour some liquid in it, make it airtight and self-repairing, and save weight over a UST tire. UST might have been the first, but that doesn't mean it's the best solution.
