Sailun S637SP. FEATURES AND BENEFITS: All season performance; Improved controllability; Fuel-efficient ride; Longer-lasting tread life; Upgraded load durability; . OVERVIEW: The Sailun S637SP is a highway terrain, all season tire made for commercial vehicles. This model is designed to be mounted on all axle positions.The ribbed tread design and its consistent road contact boost overall controllability. This element improves steering responsiveness and driving stability. The steering response time is faster and more accurate to the driver's commands, while the structure is secured against driving pressure. This tread pattern's special outer ribs firmly grip the road and offer better cornering and maneuvering. The combination of these elements gives the driver excellent control over the vehicle, providing a safe driving experience.Excellent all season performance is offered with this tread design and the all season compound. The optimal tread pattern keeps road contact at all times, while the all season compound maintains flexibility in different temperatures. These elements boost performance in dry, wet, and winter conditions. At the same time, wide tread grooves help to prevent hydroplaning. They eliminate water and slush from the footprint in order to protect the tire from slipping in wet situations.The model offers a fuel-efficient performance. The ribbed tread pattern and the special rubber compound work together to reduce the rolling resistance. This rolling resistance is the pressure that determines how much energy the vehicle uses to keep the tires in motion. As a result, it reduces fuel consumption and CO2 emissions, which leads to a fuel-conscious driving experience.These elements also enhance the tread life. They effectively prevent irregular and premature wear formations along the tread area. The tread pattern can evenly distribute driving pressure, ensuring even wear. The compound and the reduced rolling resistance decrease the treadwear rate significantly. This combination guarantees the tire's lengthened service life.The Sailun S637SP enhances load and driving durability. The strengthened internal structure keeps the ideal tire shape under load and driving pressure. As the tire does not deform under pressure, it can easily carry and withstand heavy loads. This load-carrying capacity makes this model perfect for heavy-duty 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.
