The Toyo M157 is a extreme long-haul to regional free-rolling axle position trailer tire. Designed for operations running high miles where tires are typically pulled early due to irregular wear. This fuel efficient, free-rolling axle tire is acceptable for steer axle use. The casing durability and integrity is accomplished by the four-steel-belt construction, high-elongation top belt and enhanced, high-speed casing design. This tire comes with four-straight grooves and computer-optimized tread design, deep sipes and multi-pitch grooves, which enhance wet traction while reducing road noise. Fuel consumption is minimized by the low-rolling resistant tread compound and qualifies this tire as a SmartWay-verified steer tire. The optimized 13/32” tread depth is designed to reduce free-rolling wear and tread squirm.
