This ensures the tire's usability in dry, wet, and winter weather conditions. The rib-edge sipes and zigzag grooves walls provide additional biting edges which firmly grip the road surface at all times. Stronger compound elements help to keep the tire pliable in versatile temperatures, from the heat of summer to colder winter conditions. Circumferential grooves prevent hydroplaning in wet conditions, as water and slush are dispersed from between the tread elements.
