Features

Dunlop SP 446 17.5 - 19.5
  1. 1. Directional pattern with optimized low angle V-shape

    V-shaped grooves effectively evacuate water, mud and snow while the low angle design increases robustness and resistance against high-torque stresses -> More traction and robustness

  2. 2. Open grooves and high number of wave shape sipes

    The sipes increase flexibility allowing the block to open when it enters the footprint and create additional biting edges for further increased traction on hard packed snow surfaces -> Improved traction on all surfaces through the tyre life; excellent Winter mobility

  3. 3. Shoulder tie-bars

    Tie bars increase the stiffness of the tread and reinforce the shoulder areas; resulting in less block movement and slippage -> Increased rib tear resistance in high torque applications and even shoulder wear

  4. 4. Progressive centerline humps

    Humps connect the tread blocks for limited block movement and reduced tread wear; the optimized stiffness improves late life traction -> High mileage potential and traction, reduced rolling resistance

Applications:

  • Long haul
  • Regional haul
  • Urban traffic
