Strengths:    Gread traction and cornering grip, great all round tire, light and fast
lightweight (750g for 26x2.35" and 680g for 26x2.2")
easy to mount as tubeless on Bontrager wheelsets, can be run without any sealant and pressurized with a small trail pump
great tubeless combination and bead holds on like hell

Not so expensive, £30 for 2,35", £25 for 2.2" on the rear.


Weaknesses:    thin sidewalls just like the Expert models (but when setup up as tubeless, not really a weakness IMHO as you don't get snakebites as with tubes)

Bottom Line:   
Bought them after I decided to go tubeless with Bontrager Rhythm Comp Wheelset. Bought Bontrager tape, valves, Conti Revo Sealant and these tires.

First of all, mounted them easily with hands, and inflated them with a really small pump without any sealant. This was impossible afterwards with Continental Mountain King II 2.2 Protection (didn't even inflate with a compressor without sealant) and Schwalbe Hans Dampf.

I must say, these Bontrager Wheelset + Bontrager tires are one of the best tubeless setups by far.

Tubeless was done easy and lasted for 3 months until the first problem (read later on). During these 3 months, no problems with the pressures, tires getting on/off the rim easily by the hands. The bead to rim contact is perfect even on really low pressure (the tire didn't burp once; later on, with Conti MK II 2.2 Protection i burped the tire even on high pressures like 2.5 bars).
Then, at once this happened:

Conti Revo Sealant couldn't seal the hole, so had to put a tube in it. First real "problem" and the tire-sealant tubeless combo failed on me. Lost some confidence in tubeless, but later on bought a Conti MK II 2.2 Protection tire which had thicker sidewalls and everything else, but had a lot more problems while running tubeless than the XR4 (will make a review of the tire in the future; in short the MK II 2.2 Protection couldn't be made tubeless easily with out a sealant and compressor, couldn't hold air on the sidewalls during the rides, burped from the rim once in a ride if ridden hard and lost pressure...).

Think that if I had a different sealant I'd still have the XR4 on the rear, and not a new tire.

So, the summary is this:
Great all round tire (just like the Expert model), wide as spec'd, light as AM tire, great traction on the rear on all surfaces, also great braking on the front and cornering in all conditions except very muddy surfaces. They don't loose traction easily but when they do, you know they did all they could. Not a tire that need to be leaned a lot to get the grip again. Predictable I would say.

Main negative, just like on my review of the Expert model - thin sidewalls but they are not the problem while in tubeless setup. So not really a problem if you're not used to 2ply tires that can be run with really low pressure without bending in corners.

Strengths:    Weight

Weaknesses:    you name it - no tread in middle of tire so everything sharp or even dull hits the main casing.

Bottom Line:   
First ride - cut in middle of tread, second ride puncture that Stans would not seal. Third ride tore a kno vb off - 3 flats 3 rides on trails i ride my cross bike on!! Crap!!!!

Strengths:    handling, cornering

Weaknesses:    expensive

Bottom Line:   
First tubless setup with all TLR supplies from Bontrager and took awhile to get them to hold air. The tires came with a couple of small holes in them so had to get the super juice to plug the holes first. The process wasn't as smooth I had thought but they ride great on the trails so far and are the best tires from Bontrager I've ridden on so far.

Strengths:    Light weight for its size. Open tread grips well and sheds mud very well. Rolls well for a AM tire.

Weaknesses:    Pricey

Bottom Line:   
This is for the 2012 version of the XR4 Team Issue TLR. Different tire than what is pictured here. I became interested in these tires after Mountian Bike Action gave them 5 stars in a trail test. I had been running Maxxis High Roller II's all winter in the NorthWet and could not stand them. I set these up tubeless on my DT Swiss EX500 rims using Stan's strips and SlimePro. I have only ridden them for a month and the area is just starting to dry out, so the jury is still out on wear and durability. But so far, the roll well, hook up great on wet roots, rocks, and mud. Cornering is sweet and predictable, just lean over and go.

Strengths:    Relatively light weight. Good traction.

Weaknesses:    Mounting. Durability.

Bottom Line:   
Bought these on the recommendation of the local shop to replace the terrible tires that come stock on the Fuel. Shop had a very difficult time getting them to seat right and hold air, but finally got it fixed. Took them out for their first real ride in the dirt and ended up tearing the sidewall on an little uphill climb. I've done this same climb at least a hundred times over the past 10-15 years with various tires and have never had any problems. Wafer thin sidewalls just don't cut it if you ride anywhere with any kind of sharp rocks (like most off-road trails). These are expensive tires and I have to say I am very disappointed. Definitely wouldn't recommend these tires and won't be buying these again.

Strengths:    Good grip, good tracking, rolls well for a knobby, relatively lightweight.

Weaknesses:    Sidewalls tearing

Bottom Line:   
initially I loved these tires for their great compromise between lightweight, good volume, good rolling, and rail-like grip in the looser corners, but now I am not so sure. I ride in rocks and cactus in Tucson, and it is hard on the tires. In a year I have had zero issues with any tire I have run, but have torn 2 of these soon after new. This was in features I often ride, and a lot harder regularly. A friend has also torn 2 of these in quick succession, so I do not understand how other reviewers can praise the sidewall strength, just feeling them they seem flimsy to me, and this seems to have been borne out by our experiences here. I cannot recommend these for anyone riding in rocky conditions, but they would be great if sharper rocks are something you avoid successfully.

Strengths:    Excellent grip, very strong sidewalls, very comfortable compound.

Weaknesses:    A little on the heavy side. But hey, they are TLR.

Bottom Line:   
These are excellent all-round tires, they perform well on rocky terrain, technical climbs, loose over packed, etc, haven't really tested them on muddy conditions, but on the chances I have had, they have performed well.



I run them as ghetto tubeless and they are very easy to set up, haven't have any problems in the 3 months, of course, no flats, but I always carry a tube, just in case.

Strengths:    Very good grip. Very good sealing (with Stan's).

Weaknesses:    Price. Don't know about tread life yet.

Bottom Line:   
This review is for the XR4 TLR 26 x 2.2 Team Issue.



These tires have made a bike I thought was already very good even better. I made test runs over a one hour course at 30, 35, and 40 psi. The tires are fantastic at 30 psi. I can power out of an apex with the bike leaned over. Small bump compliance at the front has drastically improved - my GPS is not longer in danger of being rattled to death. The bike now seems to roll even faster down hill. Maybe that's just the effect of not feeling the roughness of the trail.



I'm running the XR4 front and rear. I'm not a racer (I just want to ride fast) and lots of the trails I ride are loose, so I decided to not try the XR2 on the rear. The XR3, which is probably intended for my bike, isn't available yet.

I'm trying to convert my wheels to tubeless with no luck. I've got the Bontrager rimstrip, sealant and NoTubes valve. The rim is Bontrager Rhythm Elite and the tire RX4 Team Issue. Air is leaking between the tire and the rim and evenly around both wheels. It seems that some of the 2013 XR4 ti ... Read More »
