PURPOSE: A pressure measuring and alarming apparatus of a tire is provided to reduce energy consumption, and to prevent accidents by measuring pneumatic pressure of the tire conveniently and easily and checking the tire. CONSTITUTION: A pneumatic pressure measuring and alarming device of a tire is composed of a cylindrical body(1) including parts; an assembling unit(2) installed between the body and an air injection port(12); a gasket(3) sealing between the body and the assembling unit, and transmitting pressure of the tire to a pressure display moving plate(4); the pressure display moving plate sliding up and down until equalizing pressure of the tire with elastic force of a pressure spring(6); the doubling pressure spring applying elastic force in the upper part of the pressure display moving plate; a spring pressure adjuster(8) installed in the upper part of the body; and an outer case(7) mounted in the upper part of the body. A pressure transmission body transmits pressure of the tire to a tire pressure detecting unit. The tire pressure detecting unit outputs an electrical signal according to pressure of the tire, and transmits through a wireless transmitter to a wireless receiver. Pneumatic pressure is measured conveniently, and the tire is checked simply with the tire pressure measuring apparatus.
