Sumitomo ST918 245/70R19.5 133/131M G 5531785 (14 Ply)

Sumitomo ST918. FEATURES AND BENEFITS: All weather traction; Enhanced durability; Longer lasting tread life; . OVERVIEW: The Sumitomo ST918 is a highway terrain all season tire manufactured for commercial vehicles. It was made to be mounted on the vehicle's drive axle.The tire ensures excellent all weather traction. The ribbed tread design with the closed tread pattern, siping detail and zigzag circumferential grooves boost the dry, wet and winter weather road gripping ability. The maintained road contact improves the tire's performance in all weather. The zigzag circumferential grooves prevent hydroplaning by eliminating water and slush from below the tire's footprint. The all weather traction and hydroplaning resistance ensure a secure year round performance.The model's internal structure features a full steel belt casing that maintains the optimal tire shape at all times. It reinforces the tire's shape against the driving and load pressure affecting the tires and maintains the optimal shape throughout the drive. The constant road contact improves the tire's load carrying and withstanding durability. The stronger structure also stabilizes the tire's structure while the tires are in motion. The better driving stability keeps the tire close to the road surface and improves its controllability in all weather, to ensure a safer driving experience.The ST918 offers a lengthened tread life. The specially placed siping detail avoids irregular wear formations along the tread area by enabling the footprint to evenly distribute the driving pressure. In other words, the equally spread out forces of acceleration, cornering and braking actively resists irregular tread wear formations and extends the tread life and tire usability.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.
