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

Product Information

The X-Grip “Jack the Gripper” 18-inch Rear Tire (Hard compound) is designed for riders who need durability, stability, and consistent traction in demanding off-road conditions. Sized at 140/80-18, this rear tire is ideal for hard enduro, rocky trails, hardpack terrain, and extended riding where tire longevity matters as much as grip.

The hard rubber compound offers increased wear resistance while maintaining reliable traction on rock, hard soil, and mixed terrain. Its 13 mm tall V-shaped tread pattern delivers controlled forward drive and predictable braking, helping the tire track consistently on climbs, descents, and off-camber sections without excessive knob flex.

Built with X-Grip’s No-Bounce rubber compound, the Jack the Gripper Hard reduces unwanted rebound and squirm on solid surfaces, improving rider control and feedback. A reinforced bias-ply carcass provides dependable sidewall support and controlled flex, especially when riding at lower speeds or carrying higher loads. FIM-approved and mousse compatible, it’s a reliable choice for riders tackling long, technical rides where durability and stability are critical.
