The symmetric ribbed design, with the wider circumferential grooves, boosts the dry, wet and winter weather road gripping ability. The ribbed pattern maintains the tire's close road contact and enhances its grip on the road surface throughout the year with the additional biting edges. The special durable compound, on the other hand, maintains the rubber flexibility in various conditions. The circumferential grooves prevent hydroplaning. They eliminate water and slush from the footprint and upgrade the tire's grip on the road surface to boost the year round driving safety.
