Product Information
The X-Grip Jack the Gripper Rear Tire (120/90-18) brings serious grip for riders who don’t back down from tough terrain. Its V-shaped knob pattern, standing 13 mm tall, digs deep into soft ground or boulders for solid forward push, while the No-Bounce rubber compound keeps things steady on wet stones or streambeds. The bias-ply build gives it the flex to take on sharp twists or steep drops, making it a go-to for anyone hitting varied off-road conditions.
A beefed-up sidewall is where this tire shines, offering top-notch lateral guidance when you’re leaning hard into turns or weaving through rocky stretches. Whether you’re grinding up an enduro hill or carving a muddy track, that stability helps keep the bike planted. It’s designed to handle the punishment of deep, loose dirt or slick, uneven surfaces without losing its hold.
Available in soft, medium+, medium, and hard compounds, this tire lets you dial in the feel for your ride. Soft works best for biting into hardpack or rocks, hard holds up longer in loose or sandy stuff, and medium or medium+ splits the difference for mixed trails—pick what fits your usual spots or how hard you push it. With DOT and E-MARK approval, it’s good to go for a range of setups, keeping performance steady wherever you roll.
