Shake It up in Tucson!: Why Wheel Balancing

Our vehicles are not massage chairs. While we may enjoy a good vibration in an overstuffed recliner, we generally want as smooth a ride as possible in our vehicles. One way to achieve this is to keep a vehicle’s wheels in balance.

High-quality tires generally hold their balance well. But over time, wear and tear take their toll and tires can become unbalanced. Tucson drivers can tell when a front tire is unbalanced if they feel a vibration in the steering wheel. If a back tire is unbalanced, you’ll feel a vibration in your seat. You may not notice these vibrations until they get fairly serious — or until someone else drives your vehicle — because they usually develop slowly. If a vibration starts abruptly, it usually means you’ve lost a balancing weight.

The average tire rotates at about 850 revolutions per minute at 60 mph/97 kmh. When a tire is out of balance, it actually hops down the road, rather than rolling. So at 60 mph/97 kph, it is slamming into the pavement 14 times a second. That’s what creates the vibration. When tires are out of balance, they wear out more quickly. The lack of balance also causes extra wear on shocks, struts, steering components and suspension parts.
