The M157 is a free-rolling axle tire designed for operations running high miles per 32nd, from which tires are typically pulled prematurely due to irregular wear. Designed as a fuel-efficient, free-rolling axle tire, it is acceptable for steer axle use. The high miles per 32nd, with minimized irregular wear, results in maximum removal miles.

• Computer-optimized tread design, with four straight grooves, deep sipes, and multi-pitch grooves, provides enhanced wet and dry traction while also reducing road noise
• Optimized tread depth with top decoupler groove is engineered to reduce free-rolling wear and tread squirm, delivering the highest miles per 32nd
• E-balance profile minimizes growth of the tread profile and maintains a uniform and flatter tread radius for the entire life of the casing
• Industry-leading, low-rolling-resistance tread compound minimizes fuel consumption and qualifies it as a SmartWay-verified steer tire
• Four-steel-belt construction contributes to casing durability
• Enhanced, high-speed casing design resists casing fatigue
• High-elongation top belt protects casing integrity
