What does dynamic balancing primarily aim to eliminate?

Dynamic balancing primarily aims to eliminate vibration in a tire and wheel assembly. When a tire is mounted on a wheel, disparities in weight distribution or uneven wear can cause it to spin unevenly, leading to vibrations during operation. These vibrations are not only uncomfortable for drivers and passengers but can also affect the handling performance of the vehicle, leading to potential safety issues.

By performing dynamic balancing, technicians can ensure that the weight distribution is even all around the tire and wheel, thus minimizing or completely eliminating vibrations that can occur at various speeds. This process typically involves using specialized equipment that spins the wheel and tire combination to identify any imbalances. Once detected, weights are applied to counterbalance these imbalances, promoting a smoother ride.

Other factors mentioned, such as noise, tire wear, and alignment issues, while related to tire performance, are not the primary focus of dynamic balancing. Noise may result from various sources, including tread design or road conditions; tire wear is typically addressed through proper alignment and rotation; and alignment issues are a separate concern focused on the angle at which the tires meet the road, impacting handling and tire longevity.
