TIRE WEAR PATTERNS DUE TO MISALIGNMENT It should be noted that some wear patterns might be from multiple causes. Additional information may be obtained in the TMC RP 216B, Radial Tire Conditions Analysis Guide and MICHELIN Americas Truck Tire Commercial Tech Videos (MWV43100) about the “Fundamentals of Tire Wear” and “Scrap Tire Analysis.” Toe Wear – The typical wear pattern that develops from excessive toe is a feather edged scuff across the crown. Excessive toe is usually seen on both steer tires. Free Rolling Wear – Wear at the edge of a rib circumferentially, which may or may not affect the entire rib widths. Intermittent side forces due to wheel assembly instability cause contact pressure variations, resulting in this type of wear. Generally, due to excessive looseness in the suspension and/or steering components, this is also found in slow wearing positions at high mileage. Insufficient caster and excessive lateral tire/wheel runout also are contributing factors. Toe Wear Free Rolling Wear Toe Wear Free Rolling Wear Section Three: Extending Tire Life 53
