They work together to enable the tire's dry, wet and winter weather grip on the road surface. The compound keeps the rubber flexibility in versatile temperatures, upgrading the summer and winter weather performing ability. The siping and notch placement along the footprint improves the grip on the road surface with additional biting edges. The four wider circumferential grooves prevent hydroplaning by dispersing water and slush from the footprint, resulting in a safer wet weather performing ability.
