The Sailun S622 EFT tire is designed for free-rolling trailer axle positions. It has a decoupling groove that resists irregular tread wear, and wide ribs to prevent damage caused by high-scrub applications. The Sailun S622 EFT tire is also a low-rolling resistance tire designed to maximize your mileage and fuel economy, as shown by the EFT symbol on the side of the tire. The V-sipes improve traction in wet conditions and dissipate heat for prolonged treadlife, while the groove stone ejectors protect the tire against stone drilling. This helps increases the percentage of tires that are acceptable for retreading.
