FACTORS AFFECTING TIRE TREAD WEAR
The author describes the various factors that affect the rate of wear of vehicle tires, ranging from ambient temperatures, vehicle loading, and vehicle horse power. Tire wear on a 350 horsepower vehicle can be three times greater than that on a 150 horsepower vehicle. Distribution of cargo, or the type of commodities hauled, can significantly affect tire tread wear. Shifting cargo, for example meat carcasses hung from the roof of a truck, can cause a side surge, aggravate tire wear, and cause irregular wear. A high center of gravity on a loaded vehicle will cause tire wear, proportional to the crown of the pavement and curves in the road. Tire life, based on an index of 100 at a running speed of 80.5 kph, will drop to 37 at 112.5 kph. Severe grades on highways will reduce tire life from an index of 100 (level highway) to 65, while local pickup and delivery schedules wear out tires more than twice as fast as long distance deliveries.
