Tire balancing, also known as wheel balancing, is the process of correcting the uneven distribution of weight in the wheels of a vehicle. During a tire balance service, the wheels and tires are mounted onto a tire balancing machine, which spins the tire and wheel assembly to measure the imbalance. A technician then installs the correct tire weights to achieve a properly balanced wheel and tire assembly. Tire balancing is done to ensure that weight is evenly distributed around the entire circumference of the tire and wheel, which helps prevent uneven tire wear, vibration, and damage to the suspension.

Tire balancing is different from wheel alignment, which refers to the adjustment of a vehicles suspension system to keep it from veering to the right or left. Wheel alignment does not involve balancing the tires or wheels.

Signs that a vehicles tires need balancing include uneven tire wear, vibration in the steering wheel, floorboard, or seat, and poor fuel economy. It is recommended to have tires balanced every 5,000 to 6,000 miles or as recommended by the manufacturer. Tire balancing is often done during a tire rotation, after a flat tire repair, or as part of scheduled maintenance.
