Shiggy,

Have you had a chance to try these tires? What do you think of the concept?

I just sent Bontrager an email asking them to send you pair so you could review them (here).

Thanks!

I just received a box of tires from Bontrager yesterday. I now have the Tubeless Ready versions of the XR, ACX, Revolt Super X and Mud X with four bottles of Super Juice. Plus the standard Big Earl 2.5, and 29er XR and ACX.

I will have the specs posted to my site in a few days after the tires have been stretched.

The Tubeless Ready (TR) tires have a different bead shape than standard tires (I will post pics). I believe they are to UST spec (am checking with Bonty) and are VERY tight. I could not even come close to getting the tires on a few on my rims. Blistered my thumbs trying. The Mud X TR was not nearly as tight.
Bonty's TR instructions say to mount the tires on standard rims with inner tubes, inflate to 60psi and let sit (at least) overnight to stretch the beads.
Luckily I have several rims with deep center drops to mount the new tires on.

I will be riding the TRs soon, mounted on 819 rims with sealant and on standard rims with inner tubes.

Interesting that the 4 different TR models are made in three different countries (Japan [Super X], Thailand [ACX & XR] and Taiwan [Mud X]).

I think the concept (Bonty Tubeless Ready and Geax TNT) is sound. A light, mostly airtight casing designed to be used with a specific sealant. Beads designed to be used with tubeless rims. A system designed to work together from the start. TR and TNT tires are meant to be used with sealant only on tubeless rims and with inner tubes on standard rims or tubeless rims.

Thanks for sending the email!

The tires did stretch out nicely. Still a snug fit but mounted without trouble.

Kewl, when are you going to test them out?

Going to mount a set in a day or two. Have to decide which model to try first. It may be the Mud X.

Can't wait to see some reviews....

This IMO is the future fro Tubeless technolgy for Racers and people who wanrt a light set-up and UST tires from more "Trail" riding with a slighyt more robust and durable tires.

Hutchinson is also coming soon ith these style "Tubeless" tires from what I am told from a buddy in France.

To me the whole downfall with sealent is, if you want or like to change tires often it s a bit of a hassle.
But I like the idead of tires desgined to be run this way and will have little or no ssues in airing up, sealing, stayng on the rim and working properly without tube.

I have been running UST tubeless for 4 yrs (basically day 1) and "tubeless" since it was ready availabe and love it.

I just hope others will jump on the wagon very soon... Schwalbe are you listening....

Isn't this TR concept the same as the Hutchinson "UST Lite" that are UST designed but just don't have the inner butyl layer to fully seal the tires?

No. The Hutchinson Tubeless Light tires are lighter but not as close to the weight of the standard tire as the Tubeless Ready and they do not require a sealant to be used.

Bontrager's Tubeless Ready (TR) tires are basically the same weight at their standard tires. On their website, they claim the TR version is only 10g heavier; 520g for the standard 2.2 versus 530g for the TR version. The Jones XR 2.2 is closer to a true 2.0 from pictures I've seen.

Hutchinson seems to be different. For example, the Spider Lite is 580g where the Spider Tubeless Light is supposed to be 695g, but weightweenies weighed four tires that averaged 750g. The standard tubeless Spider weighs, according to the Hutchinson website 790g. So the Spider Light tubeless is a light UST tire, or at least is supposed to be at 695g, but even then still 100g heavier than the standard non-tubeless version. And, real world weight shows it to be actually 150g heavier.

I'm with DirtBoy. I think tubeless ready is the future for tubeless tires. I just wish some other tire manufactures would invest in this tubeless ready idea. I'm not too keen on running a 2.0 tire with dodgy reviews like the Jones XR TR.

Dirt Boy, aren't you running non-UST tires on your UST rims? What tires have you used, and have you had any problems?

 

[DIRT BOY]

I use UST tires most of the time...

but right now I am using Schwalbe Nobby Nic 2.1 sealed with latex.
these sealed up pretty well and easy. Only lost 9 psi in almost 2 weeks.

I have used the following "tubeless" with sealent:

Big Jim 2.25
Jimmy 2.0
Racing Ralph 2.0, 2.4
Big Albert and Little Albert
Nobby Nic 2.0
Mosquito 2.0
Python 2.0
Bull Dogs 2.1
Blue Groove 2.0
Mutano Raptor 2.4 and 2.24

And probaly others that I cannot remember.

I had 1 Albert and 1 Big Jim, blow off thier rim during inflation and break the bead. The Blue Grooves with 34psi in back, flat spotted my crossmax rims on a big hit from a root. Was very disapointed and it was not that hard.

The Mosquito with 33psi in front had the sidewall fold over on a turn a burp some air (crossmax).

Rims were/are: Crossmax (with and without Stan's rimstrips.) and Mavic XM819, Mavic 517 with Eclipse rimstrips and Stan's.

For me it has been hit or miss on how the tires behaved "tubeless" and what psi to run. it a little bit of trila and error.

With UST tires, I find the psi sweet spot very easy, always easy to mount and deal with and changing tires, ZERO flats with UST tirs in about 4 years.

Hutchison seem the easiest to seal, followed by Schwalbe then Kenda. the WTB wear a *****, but held air well.

I still prefer UST tires due the the sidewalls fee/work better at lower psi. It seems like regualr tires without tubes, it can be tricky with the psi. Seems like tubes give better stability to the sidewalls with a tube than without.

That being said, if TR tires really hit the market by others, I will be using those 75% of the time instead of UST. Just UST makes changing tires easier and faster when condtions/trails call for.

Specs for the Bonty tires are now available on my Tire Site.

 

[DIRT BOY]

Weights look ok...

but I have never been a fan of Bonty tires. I will look for your reivews...

Good work!

BTW: I don't think thos Super Motos will fit my fork. There is a just barely 3" of width to the insdie of the forks narrowest at top. If the tires also look tall.
If I go rigid, they will fit .

I still might order them and try....

Pics of the TR and standard beads

Am I understanding this right, The TR tires are good for any rim? the bead does look very different.

The tires did stretch out nicely. Still a snug fit but mounted without trouble.

fit update #2: One of the TR models is still very tight to mount. Tried soapy water on one and it worked OK. It also made it tough to grip the tire with my hands and leaves a residue.

Used Schwalbe Easy Mount fluid on the other tire. The bead slipped on easier. No problem gripping the tire and no residue.

 

[wannabeRacer]

Yeah, I agree on that one, UST tires are better but heavy. Never had puncture on full UST setup since day one (years). Now currently using standard RIM (DT 4.1d) and Maxxis UST TT Larsen & there great. Next time will try Python 2.0 for lighter setup or Bontrager's Tubeless Ready ;-)

I say this is the next step of mtb tyre technology.

Tubeless Ready tires are meant to be used with sealant (and without inner tubes) only on tubeless rims and with inner tubes on standard rims or tubeless rims.

It'll be interested to see if their sealant works as well as Stan's with punctures. As for their tire, the only one I've ever tried was a real POS (ACX I believe). It was light but way too hard to get any grip. Basically, that tire was so stiff that my kids could roll the unmounted tire in the garage.

On the other hand, my Kenda Nevegal DTC shows some signs of delamination on the outside casing...

 

[dulyebr]

Well, what's the verdict on these tires?
