IRREGULAR TIRE WEAR TRACTOR: Heel-Toe (Condition Code 182) Appearance: Drive-lugs around the tire worn high to low from the front to back edge on tread of tire. Probable Cause: High torque, pickup and delivery operations (P&D) plus mountainous terrain, high braking operations. Analysis/Correction: Drive tires should be rotated, front to rear; cross rotation is permitted, but will accelerate wear and can reduce removal mileages. With the MICHELIN® X One® tire, since you have no dual pressure differences, heel and toe pattern should clear itself up @ 1⁄3 worn. Center Wear (Condition Code 186) Appearance: Tire wears more rapidly in the center of the tread, than in the shoulders. Probable Cause: LTL (Less than Truckload) operation + high torque, incorrect air pressure. Analysis/Correction: Five tread depths should be taken in the drive position, allowing one to recognize wear conditions. Correction of drive-axle air pressure will reduce the wear pattern and enhance tire mileage. River Wear Only (Condition Code 188) Appearance: Tire exhibits circumferential wear along the rib-edges next to the major shoulder tread-ribs. Probable Cause: Characteristic of slow wear-rate of radial tires. Analysis/Correction: None, river wear should not be of concern. MICHELIN X One Tire Maintenance 45 ® ® Inset: Notice appearance of shoulder-scrub on side of tread-blocks inner/outer shoulders. 13⁄32" 14⁄32" 11⁄32" 14⁄32" 13⁄32"
