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

[DiPeter]

After changing tires, the tire pressure monitoring system needs to be reinstalled. The tire pressure monitoring, also known as tire pressure learning, involves a pressure sensor in each tire that wirelessly transmits the tire pressure to the vehicle's tire pressure control system. The vehicle's data display can then show the tire pressure for each specific tire location. There are three common types of tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): TPMS combines the advantages of both systems mentioned above. It is equipped with direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires, as a direct system does.
