Bontrager XR1 MTB Tire

This tire is designed for 20-inch wheels with an ETRTO of 57-406. While it fits most standard 20-inch mountain bike rims, you should verify your current tire's ETRTO number or rim width to ensure a proper fit before purchasing.

The XR1 is optimized for firm, fast-rolling trails. Its tread pattern is designed to maintain momentum on hard-packed dirt and gravel, though it may struggle in deep mud or loose, sandy conditions.

Yes, this is a clincher tire, meaning it is designed to be used with a standard inner tube. It is not tubeless-ready.

The maximum pressure for this tire is 50 psi. For most young riders, running slightly lower pressure can improve traction and comfort, but always stay within the manufacturer's specified range.

The wire bead is rigid, which makes the tire slightly heavier and less foldable than Kevlar-bead tires. However, it provides a very secure fit on the rim, which is helpful for ensuring the tire stays seated during aggressive riding.
