Highway Line Haul All-Position
An extremely long-wearing steer axle tire, the RY637 utilizes Yokohama’s newest Maintenance Saving Concept (MSC) technology to extend the length of the original tread and allow for a very long casing life. The benefit is an extremely efficient cost per mile over the life of the tire. Special stress control groove shapes, sipes and ribs enable stress and road contact pressure to be evenly spread across the tread surface for very even original treadwear. This creates a lower rolling resistance, which lowers fuel consumption. A five-rib design gives it great steering performance. Reduced maintenance costs overall distinguish the RY637.
Features and Benefits
Yokohama’s exclusive MSC technology enables six unique design elements to work together to enable the RY637 to combat irregular wear and to run for a very long time.
Stress Ccontrol Groove Shape & Sipes reduce river wear without increasing stone retention.
Stress control ribs reduce river wear.
Stress Wear Control Groove near the sidewall greatly reduces the occurrence of shoulder step down wear.
The snug-fitting Contoured Bead Shape allows the tire to seat evenly against the rim for extremely high uniformity levels around the entire circumference for better tire-to-rim fit, reduced friction, smoother ride and long, even wear.
