What to Do with Tire Pressure Monitoring After Changing Tires?
2 Answers
After changing tires, the tire pressure monitoring system needs to be reset, also known as tire pressure learning. Each tire is equipped with a tire pressure sensor that transmits the tire pressure wirelessly to the vehicle's tire pressure control system, allowing the car's data display to show the tire pressure for each specific tire position. The steps to reset the tire pressure are: 1. Park the car and turn off the engine, then engage the handbrake; 2. Power on the car but do not start the engine; 3. Simultaneously press and hold the lock and unlock buttons on the remote control for 5 seconds until you hear two short beeps from the car; 4. Proceed to reset each tire in the following order: front left, front right, rear right, rear left; 5. Remove the valve cap from the tire and continuously release air until you hear a short beep from the car, indicating the setting is complete. The air release process may take 10 to 20 seconds. If no beep is heard, continue releasing air.
After changing tires, the tire pressure monitoring system (TPMS) might fail, which can be quite frustrating. I experienced this situation myself last time. I went to the auto shop to get new tires, and on the way home, the tire pressure warning light stayed on, which really startled me. Later, I learned that most modern cars use direct TPMS sensors mounted on the rims, and during tire replacement, these sensors might be disturbed or require re-pairing with the system. My advice is not to rush off after getting new tires. First, have the technician check if the sensors are still properly connected, then use the reset button in your car to initialize the system—it's usually located near the center console, and you just need to press and hold it for a few seconds. If the light still doesn’t turn off, you’ll need a diagnostic tool for calibration, which a professional shop can handle in just a few minutes. Don’t ignore false alarms, as they can pose risks. Regularly checking tire pressure can save you a lot of trouble—safety always comes first.
