They work together to ensure excellent dry, wet and winter weather road gripping ability. While trailer tires do not need as good of a traction as the towing vehicle's tires do, this tire still provide great driving safety in all weather conditions. The compound maintains its flexibility, while the tread design firmly grips the road surface all year round. The wide circumferential grooves prevent hydroplaning by eliminating water and slush from below the tire's footprint and promote a safer drive.
