Direct TPMS (Tire Pressure Monitoring System) is a technology used in vehicles to monitor tire pressure in real-time. It uses sensors located inside each tire to measure the air pressure and send this information to the vehicle's onboard computer. If the pressure drops below a certain threshold, the system alerts the driver, helping to prevent tire blowouts and improve safety. This system provides accurate readings and can detect slow leaks that might go unnoticed. Direct TPMS is different from Indirect TPMS, which estimates tire pressure based on wheel speed sensors. Overall, Direct TPMS enhances vehicle safety and performance by ensuring optimal tire pressure.
