X-Grip 'JACK the GRIPPER' 18" Rear Tire (Soft) - (140/80-18)

Product Information

The X-Grip “Jack the Gripper” 18-inch Rear Tire (Soft compound) is engineered for riders who need maximum traction in extreme enduro and technical off-road conditions. Sized at 140/80-18, this rear tire is built to perform where grip is most critical—on rocks, roots, steep climbs, and loose, uneven terrain.

Using a soft, adaptive rubber compound, Jack the Gripper conforms to surface irregularities to maintain consistent contact and control. The 13 mm tall V-shaped tread pattern delivers strong forward drive under acceleration while maintaining predictable braking and side-hill stability. This design helps the tire stay planted during slow-speed, high-torque riding commonly found in extreme enduro and hard enduro environments.

The tire features X-Grip’s No-Bounce rubber compound, which improves traction by reducing unwanted rebound and deflection on slick rock and hardpack surfaces. Combined with a reinforced bias-ply carcass, the tire offers controlled flex and dependable sidewall support, especially when running lower pressures or mousse inserts. FIM-approved and mousse compatible, Jack the Gripper is a trusted choice for competitive riders and serious trail enthusiasts alike.
