Nokian designed the zLine performance tire for high-horsepower vehicles used for summer driving. This tire maintains precise handling at high speeds, giving you confidence during straight-line driving, while changing lanes on the highway, or while turning. It offers a stable and quiet ride, ensuring that you wont be disturbed by road noises or interferences. For added assurance in wet conditions, the tire uses circumferential grooves to remove water from the tread area and reduce the risk of hydroplaning.
