Tire pressure monitoring does not reset after tire repair because the tire pressure system has not been reset. The car recognizes the original tire, so the tire pressure monitoring does not reset. Additionally, it could also be due to improperly installed sensors. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver to leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct TPMS: Direct TPMS uses pressure sensors installed in each tire to directly measure tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect TPMS: When the pressure in a tire decreases, the vehicle's weight causes that tire's rolling radius to shrink, making it rotate faster than the other tires. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect TPMS essentially relies on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) overview: This system combines the advantages of both direct and indirect systems. It installs direct sensors in two diagonally opposite tires and includes a four-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 pressure data for all four tires like a direct system.
