What is the purpose of wheel dynamic balancing?
2 Answers
The purpose of wheel dynamic balancing: It ensures that the car tires remain in a relatively stable state during high-speed rotation, thereby maintaining normal driving conditions. After a car tire is repaired, its mass distribution becomes uneven, so dynamic balancing weights need to be added to restore stability. When the dynamic balancing of a car tire fails, symptoms such as severe bumpiness, abnormal vibrations, steering deviation, abnormal handling, increased fuel consumption, and uneven tire wear may occur during driving. Reasons for uneven mass distribution in car tires: 1. Errors during manufacturing, such as inaccurate axle positioning during the processing of wheel hubs or brake drums; 2. Inconsistent quality of wheel hub bolts; 3. Tire wear, out-of-roundness, or deformation; 4. Mud adhering to the tires after off-road driving.
Tire dynamic balancing is mainly about preventing the wheel from wobbling during rotation. When car tires are manufactured, their weight may not be perfectly even—some parts are heavier while others are lighter. When driving at high speeds, the uneven weight distribution causes the tire to shake violently, making it hard to hold the steering wheel steady. Dynamic balancing involves adding small lead weights to the tire's rim to adjust the weight balance and reduce vibrations. This not only makes driving more comfortable but also protects the tires and suspension system. Without balancing, the constant shaking causes uneven tire wear, leading to premature replacement, and the suspension system is more prone to damage, resulting in costly repairs. With over a decade of driving experience, I always get a dynamic balance whenever I install new tires. It's a small expense, usually around a hundred bucks, but it makes the car much more stable.
