Dunlop’s vast championship experience and development expertise has been infused into the Geomax® AT81™ cross country tyres. These offer all-round performance and provide high levels of ruggedness.

  • AT81 rear tread block shape and distribution plus DIRTuitive Grip Design (DGD) tread blocks help the tyre penetrate down through the surface dirt for extra traction across a broad range of off-road applications
  • Newly formulated high-wear-resistant rear tyre compound offers enhanced chipping, tearing and wear appearance
  • Geomax AT81 RC (Reinforced Construction) rear tyre carcass features four nylon plies
  • Lateral grooves on the shoulder tread blocks provide additional biting edges and also allow the tread blocks to be more flexible
