A tire pressure monitoring system (TPMS) is a safety feature in vehicles that continuously checks the air pressure in each tire. It alerts the driver if the pressure falls below a certain level, which can help prevent tire blowouts and improve fuel efficiency. There are two types of TPMS: direct and indirect. Direct TPMS uses sensors inside each tire to measure pressure, while indirect TPMS estimates pressure based on wheel speed and other factors. Both systems aim to enhance vehicle safety and performance by ensuring that tires are properly inflated.
