Delta Sierradial H/T Plus. FEATURES AND BENEFITS: All weather traction; Longer lasting tread life; High driving comfort levels; Enhanced controllability; . OVERVIEW: The Delta Sierradial H/T Plus is a highway terrain, all season tire manufactured for SUVs and light trucks. Delta offers a 65,000 mile treadwear warranty with this model.The tire improves the all weather traction. The model's optimal all season compound and the symmetric ribbed tread design enhance the dry, wet and winter weather grip. The detailed tread design with the ideal siping pattern enhances the grip on the road surface with additional biting edges, while the compound keeps the rubber flexibility in different temperatures. The tread's circumferential grooves prevent hydroplaning by dispersing water and slush from below the tire's footprint. This combination enhances the year round performing capability and power.The model lengthens the tread life. The symmetric ribbed tread design enhances the model's usability. The symmetric ribbed pattern and the flat footprint work together to maintain the surface contact, which enables the tire to evenly distribute the driving pressure across the tread area. The equally spread out forces of acceleration, cornering and braking avoid irregular wear formations, which enables the tire to extend its service life significantly.The tread design ensures an enjoyable drive. The tread's closed ribbed pattern helps lower the road noise levels. The closed shoulders prevent airwaves from entering the footprint and coming into contact with the tread elements. In this manner, the soundwaves are not generated during the drive, minimizing the road and tread pattern noise heard in the vehicle's cabin. The tread's symmetric ribbed pattern and flat footprint closely follow the road surface, which allows the tire to absorb the shock of driving. As a result, the tire reduces the road vibrations felt by the passengers. As road disturbances cannot ruin the passengers' driving enjoyment, the tire guarantees a comfortable and quiet driving experience.The Sierradial H/T Plus enhances the controllability. The symmetric tread design with the ribbed pattern maintains the surface contact throughout the drive. The steering becomes faster and more precise in its response to the driver's commands, while the structure is secured against the driving pressure affecting the model. The closed shoulder pattern improves the cornering ability as well. These elements provide additional biting edges gripping the road surface, which boosts the cornering and maneuvering capability. As a result, the tire ensures the driver's full control over the vehicle.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.
