A warning about the loss of pressure in the right rear tire indicates that the tire pressure is abnormal and requires calibration. Only vehicles equipped with a tire pressure monitoring system (TPMS) will display this alert. TPMS can promptly reflect tire conditions, eliminate safety hazards, and extend tire lifespan. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct TPMS uses 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 wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotational speeds between the tires, the system monitors the tire pressure. Indirect TPMS essentially relies on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Introduction: This system combines the advantages of both the direct and indirect systems. It installs direct sensors in two diagonally opposite tires and incorporates a 4-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.
