Sailun S668. FEATURES AND BENEFITS: Longer lasting tread life; Enhanced controllability; Damage resistance; . OVERVIEW: The Sailun S668 is a highway terrain, all season tire manufactured for commercial vehicles. It was made to be mounted on the vehicle in all axle positions.The model promotes an extended usability. The wide footprint's symmetric ribbed pattern ensures the tire's optimal road contact with the road surface. This allows the tread pattern to evenly distribute the driving pressure along the tread area. The equally circulated force of acceleration, cornering and braking avoids the formation of irregular tread wear formations, which successfully elongates the tread life and the tire's usability. The durable wear-resistant tire compound, on the other hand, significantly decreases the tread wear rate. This combination guarantees a secure performing capability.The tire's ideal tread pattern upgrades the controllability. The symmetric ribbed pattern's constant road contact allows the tire to closely follow the road surface at all times, which upgrades the steering responsiveness and the driving stability. This allows the tire to increase its response time and accuracy to the steering instructions, while the structure is secured against the driving pressure affecting the model. The better control over the tires enables the driver to confidently maneuver the vehicle in all conditions.The S668 actively prevents damage from harming its casing. The tread design features special stone ejecting platforms that prevent stone retention by eliminating rocks stuck between the tread elements. This avoids stone retention as the rocks are ejected from the footprint before they can drill into the tire's casing. The durable tire compound, on the other hand, resists cuts, punctures and the tread's chipping and cracking to avoid premature tread wear and damage from shortening the tire's service life.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.
