MK687

Design with three longitudinal zigzag pattern grooves provides water drainage performance in wet road and excellent steer-ability on snow/ice road. Design with big pattern block outside provides enough rigidity and excellent steer-ability. Design with multiple crossed pattern inside enlarges snow holding capability and strength of snow column, and enhanced the grip capability. The fine slots in the pattern reduced the hitting noise, the zigzag slots diffused the noise frequency, making the noise even in various frequency waves.
