Dunlop Geomax MX14 Rear Tire The Dunlop Geomax MX14 is the industry-leading sand and mud tire. Replacing the legendary MX12, it features 18% taller tread blocks and a refined scoop design to give you massive forward bite, predictable braking, and holeshot-winning traction in the softest terrain. Why Choose the MX14? Maximum Drive: Upgraded scoop-shaped knobs penetrate deeper into sand and heavy mud. Better Cornering: Advanced V-Block angles keep you planted and controlled in soft ruts. Predictable Braking: Flexible fins expand the tire's footprint when slowing down. Durable Compound: Reduced knob flex allows the tire to handle firm transition sections without tearing.
