The durable compound and the symmetric ribbed tread design work together to enhance the dry, wet and winter weather traction. The stronger compound elements optimize the rubber flexibility in versatile temperatures, optimizing the summer and winter weather performing ability. The symmetric ribbed tread design firmly grips the road surface with extra biting edges, optimizing the year round traction. The circumferential grooves prevent hydroplaning by dispersing water and slush from the footprint, upgrading the wet weather performing power.
