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

Product Information

The X-Grip “Jack the Gripper” 18-inch Rear Tire (Medium compound) is built for riders who want dependable traction with added durability for everyday enduro and off-road riding. Sized at 140/80-18, this rear tire is well suited for varied trail conditions, offering predictable performance across hardpack, loose soil, and mixed terrain.

The medium rubber compound provides a stable balance between grip and longevity, making it a solid choice for riders who want consistent performance without the accelerated wear of softer compounds. Its 13 mm tall V-shaped tread pattern delivers steady forward drive, controlled braking, and reliable side grip, helping maintain confidence on climbs, descents, and off-camber sections.

X-Grip’s No-Bounce rubber compound minimizes unwanted rebound and knob deflection, improving traction and rider feedback on rocks and uneven surfaces. A reinforced bias-ply carcass supports controlled flex and strong sidewall stability, especially during low-speed, high-load riding typical of enduro terrain. FIM-approved and mousse compatible, the Jack the Gripper Medium is a versatile rear tire for riders who want a dependable option for a wide range of off-road conditions.
