How to Calibrate Tire Dynamic Balance?
2 Answers
Tire dynamic balance calibration method is as follows: 1. Install the tire to be tested on the dynamic balance testing machine, pull out the ruler on the dynamic balance instrument to measure, and input the first controller. 2. Use calipers to measure the rim (steel ring) width of the tire to be tested; input the data of the tire to be tested on the second controller of the tester. 3. Input the rim diameter on the controller and press START to begin. 4. After lowering the tire cover of the tire dynamic balance machine, the tire starts to operate automatically and performs dynamic balance data detection. After the detection is completed, the tire stops running, and the test results are displayed on the screen of the control panel. 5. Slowly rotate the tire. When a row of indicator lights adjacent to a certain detection data is all lit, embed the counterweight block corresponding to the detection data at the 12 o'clock position on the corresponding side of the tire. 6. After the counterweights on both sides of the tire are embedded, perform the dynamic balance test on the tire again until the data displayed on the operation panel is "0", completing the calibration.
Tire dynamic balance calibration is actually quite interesting. Every time I go to the repair shop, I enjoy watching them operate. They mainly use a balancing machine that fixes the tire in place and spins it. The machine then shows which side is lighter and needs counterweights—small lead blocks attached to the inner side of the rim to balance the weight and prevent severe shaking when driving. The process is straightforward: first, clean the rim and tire surface to ensure no dirt interferes with the test, then mount the wheel onto the machine and start the rotation. Observe the machine's readings to identify the unbalanced spots, and finally attach the corresponding weight of lead blocks to secure it. Every time you get new tires or experience vibrations at high speeds, you need to recalibrate. Otherwise, it can lead to uneven tire wear and shorten their lifespan. During routine maintenance, it only costs a few dozen dollars to get it done—no hassle, just visit a professional shop.
