What is the function of wheel dynamic balance?
2 Answers
Tire dynamic balance serves the following purposes: 1. Enhance driving comfort. 2. Reduce fuel consumption. 3. Extend tire service life. 4. Ensure vehicle straight-line stability. 5. Reduce wear on chassis suspension components. 6. Improve driving safety. Below are the steps for performing dynamic balance on car tires: (1) Remove the logo in the center of the hub, install the dynamic balancer for measurement, and input data. (2) Measure the rim width and input the data. (3) Based on the data calculated by the computer, add appropriate balancing weights to both the inner and outer sides of the rim. Re-test until the standard is met.
Wheel dynamic balancing primarily addresses the vibration issue during tire rotation. Last time when my car reached 80 km/h, the steering wheel shook like a phone in vibration mode. The technician fixed it by attaching several small lead weights on the inner side of the wheel rim. The principle is actually quite simple - tires and rims can never be 100% evenly distributed, so dynamic balancing identifies the heavier spots and compensates with counterweights. If neglected for a long time, steering wheel vibration would be the least concern - the real damage is to the suspension system: shock absorbers may fail prematurely, bearing wear accelerates, and even the tires can develop wave-like wear patterns. It's recommended to perform dynamic balancing every time after getting new tires or tire repairs, as spending just dozens of yuan can prevent thousands in major repair costs.
