The desian with 3D grooves increased the contacting area with ice and snow and improved the arasp forceThe pattern desian with continuous pattern in the tire cap effectively increased the rigidity of the pattern the slant fine and wave grooves ensures better stability of steerability.

The optimized design arrangement of stud hole increases the grasp force on snow/icy road and reduced the noise providing better steer ability and traction force on snow/icy road.

The design with directional V-Shape grooves enhances the flowing of water and snow in the grooveswhich can effectively drainage the snow and water and provices better traction and arasp force in the snow/icy road.
