What does four-wheel dynamic balance mean for a car?
2 Answers
Four-wheel dynamic balance refers to performing dynamic balance tests on all four wheels. During the test, the four wheels need to be removed and placed on a specialized machine for rotation. The machine then detects the lighter areas on the wheels, and technicians will install counterweight lead blocks in these lighter areas. Dynamic balance is crucial for high-speed rotating components in a car. Many high-speed moving parts inside the car's engine undergo dynamic balance tests. As a high-speed rotating component, the wheels must also undergo dynamic balance testing. However, dynamic balance tests do not need to be performed regularly; they only need to be done each time the tires are replaced.
As a car owner, I once experienced some steering wheel vibrations while driving, especially noticeable on highways. Later, I learned it was due to an issue with the wheel balancing. Simply put, wheel balancing involves checking each wheel to ensure they rotate without irregular wobbling. This is typically done at a repair shop using a machine. If an imbalance is detected, small lead weights are attached to the wheel rim to adjust the weight distribution. This makes driving smoother, reduces vibrations, and helps prevent uneven tire wear. Neglecting wheel balancing for too long can accelerate tire wear, increase fuel consumption, and make driving tiring over time. I recommend getting it checked at a professional shop every time you install new tires or every 10,000 to 20,000 kilometers to maintain comfort and safety.
