How often should wheel balancing be done? With enough miles, wheels lose their balance. Out-of-balance tires affect both the quality of the handling of your vehicle and the wear of the tires. While wheels and tires are machine-made, and theoretically uniform, in reality, there are slight irregularities that make them slightly heavier on one side than the other. As the tread on your tire wears down, the distribution of weight around the tire changes. This leads to an imbalance that causes the vehicle to shake or vibrate.
During a wheel balancing service, the technician will use a calibrated spin balancer and usually will test both static (non-moving) and dynamic (moving) balance. One guideline to remember is to have a tire balancing service each time you have your tires rotated (usually every 5-6,000 miles).
