PURPOSE: A pneumatic pressure regulator of a tire is provided to improve traveling stability and braking efficiency by controlling pneumatic pressure of tires individually according to traveling state, and to repair conveniently by detecting defect automatically. CONSTITUTION: A pneumatic pressure regulating device of a tire is composed of an air compressor(3); an air tank(4) storing air from the air compressor; a pneumatic pressure supply control unit(5) supplying pneumatic pressure to tires(6a,6b,6c,6d) selectively from the air tank; a pneumatic pressure measuring sensor(7) of the air tank; tire pressure measuring sensors(9a,9b,9c,9d) installed in tires to measure pneumatic pressure of tires individually; a solenoid valve(10) shutting off the air tank and the pneumatic pressure supply control unit selectively; a control unit(2) controlling the air compressor, the solenoid valve and the pneumatic pressure supply control unit by receiving signals from sensors; a display unit(8) alarming the abnormality of pneumatic pressure to a driver according to the output signal form the control unit; and an input unit(1) inputting the control value in the control unit. Traveling stability is improved with regulating pneumatic pressure of the tire individually.
