How is tire dynamic balancing performed?
2 Answers
Tire dynamic balancing is performed as follows: 1. Remove the tire from the vehicle and secure it on the balancing machine. 2. Input the required values as prompted by the balancing machine. 3. Rotate the tire to read the dynamic balance deviation value. 4. Add balancing weights for correction. 5. Reinstall the corrected tire onto the vehicle, completing the dynamic balance correction. Dynamic balancing should be performed under the following circumstances: 1. After replacing a new tire or repairing following a collision accident. 2. When there is uneven wear on one side of the front or rear tires. 3. When the steering wheel feels excessively heavy or floats and shakes during driving. 4. When the vehicle veers to the left or right while driving straight. 5. Even in the absence of the above conditions, for maintenance purposes, it is recommended to perform dynamic balancing on new vehicles after 9 months of driving, and subsequently every six months or 10,000 kilometers.
Tire dynamic balancing is mainly performed to ensure the wheel rotates evenly and smoothly. First, the wheel needs to be removed from the vehicle and securely mounted on a specialized balancing machine. Once the machine is turned on, it spins the wheel at high speed, using sensors to detect which side is lighter or heavier, usually displaying numbers on the screen indicating the specific offset. Then, counterweights are added to designated positions on the wheel rim to adjust the balance—these could be lead weights or more modern adhesive balancing weights. The process is repeated with testing and adjustments until the numbers stabilize around zero, indicating proper balance. If unbalanced, it can cause severe steering wheel vibrations at high speeds, affecting handling and even wearing out suspension components, so it should be done every time new tires are installed or after a tire repair. Additionally, don’t forget to check if the counterweights are securely attached; otherwise, if they fall off while driving, the imbalance will return. The entire process is straightforward and usually takes about ten minutes, but choosing the right adapter and ensuring machine accuracy are crucial.
