Siping

Siping is one of the most important tire technologies for wet and snow traction. Nitto's revolutionary 3D multiwave and 3D Interlocking sipe designs provide traction without sacrificing handling.

Circumferential Grooves

Three wide and deep circumferential grooves improve water evacuation, providing increased wet handling and traction.

Quiet-Wall Technology

Serrations on the walls of the grooves interrupt the air-flow, reducing the high-frequency sound vibrations when driving. to provide a quiet and comfortable ride.

Tread Block Stability

Large tread blocks on the outside of the tire provide stability, helping you to safely navigate corners.
