Dunlop Grandtrek ST20. FEATURES AND BENEFITS: High driving comfort levels; All weather traction; Enhanced controllability; . OVERVIEW: The Dunlop Grandtrek ST20 is a touring, all season tire manufactured for passenger vehicles.The tire is easily controlled in all weather. The tread's center rib pattern and rounded shoulders improve its road contact throughout the drive. This center tread area improves the steering responsiveness and the driving stability with the constant surface contact. The model is quicker and more precise in its response to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. The rounded shoulder detail enhances the cornering and maneuvering ability. These blocks increase the number of biting edges gripping the road during the model's maneuvering, guaranteeing a safer performance.The model offers a comfortable and quiet drive. The tread design features a five-pitch sequence that helps lower the road and tread pattern noise generated during the drive. This sequence creates a sound frequency that negates the soundwaves at the moment they are generated, before they can reach the vehicle's cabin and dampen the passenger's driving enjoyment. The internal structure's Dimensionally Stable Polyester casing and special bead apex decrease the road vibrations felt while the tires are in motion. This construction ensures a closer surface contact, enabling the tire to absorb the shock of driving, which reduces the vibrations felt by the passengers. This combination ensures an enjoyable driving experience.The Grandtrek ST20 provides excellent all weather traction. The symmetric tread design and the all season compound work together to increase the dry, wet and winter weather road gripping ability. The tread design upgrades the grip on the road surface all year, while the compound keeps the rubber flexibility in different temperatures. The circumferential grooves prevent hydroplaning by dispersing water and slush from below the footprint. As a result, the tire significantly improves the all weather performing safety, ensuring a safer drive. 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.
