Sailun Terramax H/T. FEATURES AND BENEFITS: All weather traction; Hydroplaning resistance; Longer lasting tread life; Slight off-road capability; Reduced road noise levels; Vibration-free drive; . OVERVIEW: The Sailun Terramax H/T is a highway terrain, all season tire manufactured for SUV and light trucks. Sailun offers a 50,000 mile treadwear warranty with this tire model.This model offers excellent all weather traction and it grips the road well in dry, wet and winter weather thanks to the tread pattern featuring full depth sipes. These sipes maintain the tire's great grip, even as it wears out as they do not disappear with the wear. The four channel zigzag grooves maximize the tire's water dispersing ability and improve its resistance to dangerous hydroplaning. The tire is able to perform well all year, making it very weather versatile.The optimized tread block design, the zigzag grooves and the full depth sipes help extend the usability of the tire. The full depth sipes maintain the model's great all year traction, even as the tire wears out. The optimized tread block design and the zigzag grooves equally distribute the driving pressure across the tread area of the tire. The even distribution of the accelerating, braking and cornering force prevents irregular wear on the tire. The longer lasting, even wear increases the tread life.The model offers slight off-road capabilities. Its main purpose is everyday highway driving, however the open slotted shoulder tread design enables it to have good traction in slightly off-road conditions, such as dirt paths. It offers more versatility in this manner, as it enhances safety and enables both on- and off-road driving.The open slotted shoulder's variable pitch design also helps reduce the road noise heard in the cabin of the vehicle. The variable pitch creates sound frequencies while the tires are in motion that cancel out the road and pattern noise generated during the drive. The Terramax H/T's tread pattern follows the road closely in all weather. The maintained road contact decreases the road vibrations that are felt by the passengers. This offers a comfortable and quiet the 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.
