Yokohama Tire Corp. is releasing its newest premium-grade, long-haul trailer tire, the RY587 MSC, to meet the increased maintenance demands of commercial truck operators. Based on the design of the RY637 steer axle tire launched last year, the new tire is designed for on-highway trailer applications. "With fuel and vehicle maintenance costs a constant concern for transportation companies, our engineering teams have been relentless in pursuing cost-reducing designs," said director of commercial sales John Cooney. "The RY587 MSC is an example of our commitment to cost-saving and high-performance tire designs." Yokohama said the RY587 MSC reduces both suspension component wear as well as irregular tire wear, using technology developed on steer axle tires, like the RY637. The RY587 MSC also uses Yokohama's Stress-wear Control Groove, which helps reduce tire and suspension component wear by minimizing pressure at the edge of the tread. Yokohama said reduced pressure results in reduced free rolling wear and longer, even wear over the life of the tire. Stone ejector ribs prevent stones from reaching the bottom of the groove where premature casing damage can start.
