Yokohama Tire Corp is releasing its newest long-haul trailer tire — the RY587 MSC, which reduces suspension component wear and irregular tire wear, using technology developed on steer axle tires like the RY637.

The new tire also uses Yokohama's Stress-wear Control Groove (SCG), which reduces tire and suspension component wear by minimizing pressure at the edge of the tread. Stone ejector ribs prevent stones from reaching the bottom of the groove where premature casing damage can start.

Yokohama designed a Belt Edge Cushion and Edge Cover Sheet that bond together and allow steel belt flexibility. The company also incorporated a fuel-efficient rubber compound into the RY587 MSC. The compound provides long wear and reducing rolling resistance — without sacrificing grip.

Casing design is based on a computer-generated casing profile to maximize overall tire life by reducing heat and internal tire stress. The RY587 MSC is designed using existing Yokohama Strain Energy Minimization (STEM) technology.

Tire design also includes enhanced wet traction. A five-rib tread design allows for effective water evacuation from under the tread, reducing hydroplaning. Extra-deep sipes maintain a sharp edge effect, boosting wet grip until late stages of wear.
