The systematic repositioning of tires on vehicles equipped with dual rear wheels is a maintenance procedure designed to promote even wear across all tires. This practice addresses the unique wear patterns associated with dually setups, where inner and outer tires on each side of the axle experience different stresses and loads due to variations in road camber, cornering forces, and weight distribution. The goal is to extend the lifespan of the tire set and maintain optimal performance characteristics.
Implementing this procedure offers several advantages. Consistent tire wear improves overall handling and stability, particularly when towing or carrying heavy loads. It also helps to maximize fuel efficiency and reduce the likelihood of premature tire failure, leading to cost savings over the vehicle’s operational life. Historically, regular tire maintenance has been a cornerstone of preventative fleet maintenance programs, reflecting its impact on safety and operational economics.
