A tire air pressure monitoring system for a vehicle is disclosed. The tire air pressure monitoring system includes a detector configured to detect tire air pressures of tires of the vehicle; and a processing device. The processing device is configured to output a first notification that is an alarm representing a reduced tire air pressure state based on at least one of the tire air pressures less than or equal to a first threshold, detect a predetermined opportunity at which the tires can be filled with air, and output a second notification, differently from the first notification, based on a detection of the predetermined opportunity and at least one of the tire air pressures less than or equal to a second threshold but greater than the first threshold, the second threshold being greater than the first threshold.

A digital measuring device includes a housing, at least one measuring head, at least one measuring sensor, at least one digital measurement circuit, and at least one power supply unit. The measuring head is arranged outside the housing. The measuring head functions to carry out an operation of tightening a tire valve core, connecting a valve stem, or measuring tire tread. The measuring sensor is arranged inside the housing and coupled to the measuring head to measure and detect a detection signal indicating an output of a tire valve core tightening torque, a tire pressure, or a tire tread depth. The digital measurement circuit is connected to the measuring sensor for computing, displaying, and issuing an alarm regarding the tightening torque that the measuring head applies to tighten a tire valve core, the tire pressure, or the tire tread depth. The power supply unit supplies a desired direct-current working power to the measuring sensor and the digital measurement circuit. As such, a device that is capable of digital measurement, displaying, and issuing an alarm regarding the tire valve core tightening torque, the tire pressure, or the tire tread depth is formed.
