The ribbed tread design, with the large grooves, and the all season compound boost the road grip in dry, wet, and winter weather conditions. In other words, the tread design maintains the road contact all the time, while wide grooves prevent hydroplaning. At the same time, the all season compound keeps the rubber flexible in summer and winter conditions. The ribbed tread design, all season compound, and wide circumferential grooves promote a safe year-round driving experience.
