This combination helps to upgrade the dry, wet, and winter weather traction. In other words, the stronger compound's year round rubber materials optimize the flexibility in versatile temperatures. The sipe and groove placement along the tread helps to enhance the grip on the road surface with extra biting edges. Circumferential grooves and open shoulders keep the footprint clean of water and slush. This makes sure the tire's surface contact is optimized, even in wet conditions, preventing hydroplaning as well.
