Incorrect balance is the largest cause of vehicle vibration. A wheel is out of balance when one area is heavier or lighter than the rest. This can cause uneven treadwear, increased vibration, and increased stress on the front-end parts that may cause them to wear prematurely.

You should have your wheels balanced and aligned:

• whenever a tire is replaced
• at the first sign of vibration or irregular treadwear
• when a balance weight is moved or removed
• whenever you purchase new tires
