Does the Tire Pressure Monitoring System Need to Be Reinstalled When Changing Tires?

Replacing two tires does not require resetting the tire pressure monitoring system. Only when swapping the front and rear tires is it necessary to reset the tire pressure monitoring system. Reason for resetting: After tire rotation, the tire pressure monitoring system must be reset, also known as "tire pressure learning." Each tire is equipped with a pressure sensor that transmits tire pressure data wirelessly to the car's tire pressure control system, allowing the vehicle's data display to show the pressure of each specific tire location. For example, if the left front tire is moved to the right rear position without resetting the system, the car will still recognize it as the left front tire rather than the right rear tire. Reset method: After parking and turning off the engine, engage the handbrake. Power on the car but do not start the engine. Simultaneously press and hold the lock and unlock buttons on the remote for 5 seconds until you hear two short honks (not too loud). Then, follow the sequence of left front, right front, right rear, and left rear to reset each tire. Start with the left front tire: Remove the valve cap and continuously deflate (or inflate) the tire until you hear a short honk, indicating the tire is set. Deflation may take 10 to 20 seconds. If no honk is heard, continue deflating. Repeat the same method and sequence for the remaining three tires. After the last tire is set, the car will immediately emit two short honks.
When I changed my tires before, I also thought about the tire pressure monitoring system (TPMS). If you're just replacing the old tire tread with a new one, the sensors are usually still fixed on the wheel rims and don't need reinstalling, but you should be careful not to damage the sensors during the process. However, if you change the wheel rims altogether or if the sensors themselves have issues, you might need to reinstall them or have the system relearn to recognize them. The tire pressure monitoring system is quite important—it provides real-time alerts about pressure changes, helps avoid blowouts during high-speed driving, and enhances road safety. I recommend checking whether the tire pressure readings are accurate after changing tires. If they're off, take your car to a professional repair shop immediately—they can reset it with the right tools. Don't try to fix it yourself to avoid damaging the wiring. Also, pay attention to the condition of the sensors during regular maintenance to save yourself a lot of trouble.
