Product Information
The X-GRIP Jack the Gripper 140/80-18 (Hard) rear tire is designed for extreme durability and stability on firm, technical terrain. With a reinforced carcass and stiff rubber compound, this tire is ideal for hard enduro, mountain trails, or any surface with packed soil, exposed roots, or embedded rocks.
Its 13 mm tall V-shaped knobs deliver dependable traction while minimizing wear, even in abrasive environments. The tread spacing helps prevent buildup while maintaining ground contact on climbs and descents. The No-Bounce rubber compound ensures controlled rebound, especially on downhill or rocky stretches. The hard compound holds its shape well under load and temperature, making it a reliable choice for long days and high-demand riding.
Whether you’re pushing through dry riverbeds or navigating alpine singletrack, the Jack the Gripper Hard is built to keep traction steady and your rear tire planted. Fully FIM compliant and compatible with mousse inserts for low-pressure performance.
