The present invention relates to a receptor of tire pressure monitoring system for vehicles. The receptor consists of a wiring substrate board of which is equipped with a radio-frequency receptor, a micro controller, a liquid crystal display, a vibration monitor and a buzzer. The vibration monitor could sense the vibration while the door is being opened or closed and hence start the tire pressure monitoring system. The radio-frequency receptor can receive the data and convert it to be shown on the liquid crystal display. While the tire pressure is unusual, the buzzer starts the audio alerting sound to remind the driver checking the tires. It can improve safety driving.
