Tire and Wheel Balancing: Notes
WARNING: This page is about a different car, the 2008 Suzuki Swift +, 2008 Pontiac Wave, and 2008 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
There are 2 types of tire and wheel balancing: static and dynamic.
Static balance is the equal distribution of weight around the wheel. Assemblies that are statically unbalanced cause a bouncing action called wheel tramp (1). This condition may eventually cause uneven tire wear.
Dynamic balance is the equal distribution of weight (2) on each side of the centerline so that when the assembly spins there is no tendency for it to move from side to side. Assemblies that are dynamically unbalanced may cause wheel shimmy.
