Travelstar UN33. FEATURES AND BENEFITS: All weather traction; Enhanced controllability; Comfortable driving experience; . OVERVIEW: The Travelstar UN33 is a performance and high performance all season tire manufactured for passenger vehicles.The tire promotes great all season traction. The tread pattern's asymmetric tread design features detailed siping, wide grooves and ribs that keep the tire's road grip in dry, wet and winter weather. The individual tread elements find excellent grip on the road surface, and ensure a firm road grip on all weather road surfaces. The tread design's wide grooves actively resist hydroplaning by eliminating water and slush from below the tire's footprint. The better hydroplaning prevention and the all season traction ensure a secure year round performance.The maintained road contact increases the tire's controllability. The ribbed asymmetric tread design keeps its contact with the road surface at all times, which improves the steering responsiveness and driving stability. In other words, the steering is faster and more precise in its responsiveness to the driver's commands, while the structure is stabilized against the driving pressure affecting the tires while they are in motion. This enables the tire to evenly distribute the driving pressure along the tread area, preventing the deformation of its structure under the high speed driving pressure. The upgraded pressure distribution allows the tire to perform to its best capability while keeping its optimal shape.The UN33 offers a quiet and comfortable driving experience. The tread features an optimized variable pitch sequence that manages to negate the road noise. The variable pitch sequence generates a sound frequency that negates the road noise created while the tires are in motion. The decreased road noise levels guarantee a quiet drive. The asymmetric optimized footprint enables the model to closely follow the road surface which absorbs the shock of driving. In this manner, the road vibrations felt in the vehicle's cabin are reduced, ensuring a comfortable and enjoyable high speed performance. 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.
