How to Install a Tire Pressure Monitoring System in a Car?

[LaChristopher]

Deflate the tires; use a tire changer to squeeze out space near the tire valve; remove the original tire valve; install the tire pressure monitoring system and gasket; install the fixing screws and tighten them to the specified torque. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, with alerts for tire leaks and low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. Wireless transmitters send pressure data from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts when 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 shrink, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors 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): It combines the advantages of both systems above, equipping direct sensors in two diagonally opposite tires and incorporating a 4-wheel indirect system. Compared to a full direct system, this hybrid system reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
