Hankook Ventus ST. FEATURES AND BENEFITS: All weather traction; Reduced road noise levels; Vibration free drive; Precise steering responsiveness; Longer lasting tread life; Rim protector; . OVERVIEW: The Hankook Ventus ST is a performance high performance, all season tire manufactured for SUVs. Hankook offers a 50,000 mile treadwear warranty with this model.The tire provides first-rate all weather traction thanks to its special V-shaped tread design. It grips the road well in dry, wet and winter weather and the tire compound does not lose its excellent traction in the colder winter temperatures. The tread pattern also offers safe water and slush evacuation to increase the wet weather traction and the model's hydroplaning resistance. This ensures that the tire is safe to use all year.A quiet and comfortable driving experience is guaranteed. The DDPT, or dual depth pitch theory, with the multiple sub pitch concept negates the road and pattern noise generated while the tires are in motion. It creates a sound frequency that cancels out the road noise heard in the vehicle's cabin. The internal structure's jointless bead wire improves the comfort levels by absorbing the road shock and vibrations that affect the ride quality. The lowered road vibrations and pattern noise improve the enjoyment of the drive.The internal structure features a bead filler, a jointless two-cap ply and two high tensile steel belts. All of these ensure that the tire maintains its constant road contact and that it does not deform under the external driving pressure affecting it. As the tire keeps its contact with the road and its optimal shape, its steering responsiveness and accuracy are increased. The tire is quick and precise in its responsiveness to the driver's instructions, enabling them to safely and confidently control the tire in all conditions.The computer optimized ply line development and the footprint shape optimization increase the tread life. They evenly spread the driving pressure out across the tread area. The better distribution of the forces of acceleration, cornering and braking prevents irregular tread wear from forming on the tread surface. This extends the tire's usability and tread life.The Ventus ST's sidewalls are designed in a way that they protect the rims. They guard the rims from accidental curb and outer shock damage and scratches. 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.
