Zeta Verdant. FEATURES AND BENEFITS: All weather traction; High speed controllability; Improved comfort levels; . OVERVIEW: The Zeta Verdant is a performance and high performance, depending on the speed rating of the size, all season tire manufactured for passenger vehicles. This model has some touring, T speed rated sizes as well. Zeta offers a 60,000 mile treadwear warranty with this model.The tire promotes first-rate all weather traction. The symmetric tread design, with the detailed siping and notch pattern, and the all season tire compound increase the model's performing capability in dry, wet and winter weather. The tread's detailed elements guarantee a firm and consistent grip on the road surface throughout the year, while the tread's optimal all weather compound keeps its flexibility even in colder temperatures. The circumferential grooves increase the water and slush dispersing ability, which improves the tire's hydroplaning resistance. In this manner, the tire boosts its year round driving safety.The tread design and the tire's internal structure work together to ensure a secure controllability and driving experience. The tread design features a continuous center rib that maintains the tire's road contact during the drive. This increases the steering responsiveness and the driving stability significantly. The better and more precise steering response and the stabilized structure provide an enhanced control over the vehicle. The high-density siping and notch pattern upgrades the braking ability. They increase the number of biting edges gripping the road surface, creating friction between the tire and the road surface and shortening the braking ability. The tire's steel belt structure is strengthened with a jointless full nylon cover that maintains the optimal tire shape under the high speed driving pressure. As a result, the tire is capable of safely performing at its greatest high speed ability.The Verdant also offers a comfortable drive. The stronger construction also features a polyester body ply that keeps the tire's optimal shape under the driving and load pressure affecting the model. This construction allows the tire to closely follow the road surface at all times. This enables the tire to absorb the shock of driving while the tires are in motion, decreasing the road vibrations felt in the vehicle's cabin. Subsequently, the model promises a comfortable and enjoyable driving experience. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
