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

[LaGeorge]

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 installed in each tire. These sensors transmit the tire pressure wirelessly to the vehicle's tire pressure control system, allowing the car's data display to show the pressure of each tire at its specific location. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and the data for each tire's pressure is displayed. The system automatically alerts the driver 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 the tires, the system monitors the tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of the two aforementioned methods. It is equipped with direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only direct systems, this hybrid approach reduces costs and overcomes the indirect system's inability to detect low pressure in multiple tires simultaneously. However, it still cannot provide real-time pressure data for all four tires as effectively as a direct system.
