Tires that are out of balance can cause a vibration that can lead to driver fatigue, premature or uneven tire wear, and unnecessary wear and tear on your vehicle's suspension. Tires should be balanced when they are mounted on wheels for the first time or when they are remounted after being repaired.
Pay serious and immediate attention to vibrations. The solution could be as simple as rebalancing your tires, but it could be as dangerous and complicated as fixing your steering and suspension system. Visit your local authorized Michelin tire dealer at the very first sign of vibration or "shimmy." If rebalancing doesn't eliminate the vibration, have the alignment and/or suspension system components checked.
