Dunlop's vast championship experience and development expertise has been infused into the next generation of off-road tires: the all-new Dunlop Geomax AT81. These new Geomax tires offer more all-around performance plus higher levels of ruggedness for off-road racing and riding. Formulated high-wear-resistant rear tire compound offers enhanced chipping, tearing and wear appearance. Rear center blocks are arranged in-line to provide a larger contact patch for maximum traction. Geomax AT81 rear tire carcass features two nylon plies. Dunlop's "plush pad" recess design between tread blocks enhances compliance for bump absorption and ride comfort.

AT81 rear tread block shape and distribution plus DIRTuitive Grip Design (DGD) knobs help the tire penetrate down through the surface dirt for extra traction across a broad range of off-road applications. Front tire construction includes two plies of nylon wrapped with a third ply of polyester for a strong base. Lateral grooves on the shoulder knobs provide additional biting edges and also allow the knobs to be more flexible.
