Drive axle tyre for mixed service on/off-road use, suited to construction and heavy-duty applications requiring traction, casing strength and resistance to cut and chip damage.

The Giti GDM686 is developed for drive axle fitment in mixed service fleets operating across rough and unsealed environments. Its tread and casing design support traction, wear stability and casing integrity, helping maintain consistent performance and controlled operating costs in demanding duty cycles.

  • Directional deep tread improves traction and self-cleaning on loose surfaces
  • Large tread blocks resist punctures and tearing in harsh environments
  • Wide grooves support braking stability and debris evacuation
  • Reinforced casing structure supports durability under heavy loads
  • Anti cut and chip compound reduces tread damage from debris
  • Deep tread depth supports extended removal mileage
