The Bontrager XR4 Team Issue TLR has a stiff sidewall yet feels supple and plush on rough terrain.

Mtbr’s Take

After riding the Bontrager XR4 Team Issue TLR tire in nearly every condition, I am hard pressed to find one it cannot handle. Bontrager bills the XR4 as an aggressive trail tire, but tread pattern and 120 TPI casing make it much more versatile.

Medium knobs all around offer consistent performance in corners and braking, though cornering knobs could be a bit higher for really digging in. That said, bite is still adequate. The Bontrager XR4 Team Issue TLR carries speed on flats and flowy sections of trail better than most race tires I have ridden. Grip and control, especially when braking and driving in loose terrain is the Bontrager XR4 Team Issue TLR’s sweet spot.

L shaped side knobs are shallow, but still allow riders to dive in and out of corners confidently.

I paired up these Bontrager XR4 Team Issue TLR tire with Stan’s Baron wheels, which have an inner rim width of 35mm. This increased the footprint of the XR4’s voluminous casing. Mounting was a snap and a pop, as I was able to set them up tubeless with no compressor, just a standard floor pump.

The Bontrager XR4 Team Issue TLR have a secure bead, not tight, but it does require a tire lever to get on and off. The Bontrager Inner Strength casing feels well made and consistent, with smooth lines and rubber distribution throughout the casing.

The Bontrager XR4 Team Issue TLR’s staggered solid center line knobs create excellent braking and acceleration.

Riding hours on rocks, roots, and even some city curbs have yet to cause a flat or even a leak. And while the Bontrager XR4 Team Issue TLR’s round profile may throw you off, don’t second guess. This tire can rip turns and bite in hard when you sprint out of turns. An open knob pattern carries speed well on flats and flowy sections of trail. Sharp block like knobs shed mud debris well enough and will not affect braking grip.

This tire excels in control and grip, most notably in braking traction. I took chances on descents, braking late, knowing that my tires will slow me predictably. I attribute this to solid centerline knobs and rubber compound choice. The Bontrager XR4 Team Issue TLR’s have a 61a/50a dual-compound, which is used in all of Bontrager’s top-tier tires.

Bontrager XR4 27.5 2x2.8 Plus

The Bontrager XR4 Team Issue TLR’s measured the equivalent of 2.74” on our Stan’s Baron rims.

Bottom line, while you can never say a tire does everything well, the Bontrager XR4 Team Issue TLR’s come pretty close. They may not be the fastest on pedal heavy sections of trail or fire roads, but when your bike is pointed downhill into gnarly roots and slick rocks, this is a great tire to have. That’s why we can enthusiastically recommend them for riders looking for a super tactile feel, and great grip over rough terrain.

    Only the plus sizes cost that much. The XR4 2.4 is $55 which is a bargain. They do wear fast on the rear, but not noticeably fast (to me) on the front.

    Um, pretty much all premium MTB tires cost more than low end car tires. Low end car tires are cheap, and ride like krap. I bought a set just to get my car rolling (which for the set was cheaper than the set of tires on my MTB) and gave them away as soon as I could. They drove horribly, I considered them almost dangerous.

    I’ve got the 60TPI 29×2.6 version of these on my Krampus. Seems pretty similar to DHF/DHR for knob height and pattern, maybe not quite as tall of knobs. Definitely more traction than the 29×3 Chupacabras I ran on the original build.

  • Plusbike Nerd says:

    Nice to see that this tire is true to size. A true 2.8 tire should measure 2.8in on an i40mm rim and 2.75in on an i35mm rim. Bontranger tires are usually the most expensive tires you can get. I think Trek makes them for their new bikes but doesn’t expect to sell many as replacements. There are many other similar great tires of this type for much less money and especially if you buy them online. The 27×2.8 Maxxis Minions are one example which you can find online for about $75.

    Have this tire on front (it’s a 26 x 2.35). Bought is for $55 CAD several years ago.
    Love this tire absolutely awesome. Way waaaay better than the Nevegal it replaced.
    Never lost traction ever, loose or hardpack up or down or around.
    Long wearing too no torn knobs, sidewalls tough.
    Paired up with an XR3 on the rear is a great combo !
