We recommend having your tires and wheels balanced when first installed, when there is evidence of balance-related tire wear, or every 10,000 to 12,000 miles as a measure of productive maintenance. Unbalanced tires can lead to uneven wear, vibration and potentially unsafe driving conditions. Vibration-free tires enhance ride control and performance, as well as extend the lifespan of a set of tires. From a safety standpoint, unbalanced tires can cause excessive vibration at high speeds, reducing handling and control which can lead to an accident. From an environmental point of view, balance-related wear will cause tires to wear prematurely.
