Bontrager XR4 Team Issue TLR MTB Tire

Model 579287

The XR4 Team Issue TLR tire offers incredible grip and fast-rolling efficiency in a new and improved tread pattern with 120 TPI casing. Save yourself from punctures with our Inner Strength sub-tread protection while squeezing out every bit of cornering traction with the 61a/50a dual-compound rubber. This tire really is that good.

Product details

An aggressive trail tire that excels in loose and rocky conditions
An aggressive tread design provides confident cornering and braking traction in demanding terrain
The Tubeless Ready (TLR) tire is engineered for easy tubeless set up and puncture protection
Supple and strong: the Inner Strength casing provides lightweight sidewall protection
The lightweight 120 TPI casing provides great ride feel and tire performance

"Mud, grease, wet roots, hard packed, leaf covered, you name it—these XR4s stick to everything and always tempt me to push harder and harder"

"One of our favorites...Excellent, stable but smooth ride feel, trustworthy all-conditions grip and reasonable roll"

"They roll quickly, are predictable, brake well, provide excellent hold off-camber and are a reasonable weight with ample protection"

"They’ve held up well, excelled in some of the sloppiest conditions I’ve ever ridden in and been both predictable and reliable in all situations"
