Fast Rolling With Fierce Traction
The XR3 is the perfect tire for riders who want traction and speed in a variety of trail conditions. Smaller center knobs allow you to maintain speed while aggressive side knobs add cornering confidence. Pair this with an advanced rubber compound and Inner Strength casing and you've got a great tire for race day or just an afternoon out on the trails.

If for any reason you're not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
