PURPOSE: A device for displaying pneumatic pressure of a tire is provided to make a driver easily check normal pneumatic pressure of the tire from a driver's seat, to secure a stable driving, and to prevent accidents caused by the pneumatic pressure by quickly coping with problems that the pneumatic pressure is lower than the reference value or the tire punctures. CONSTITUTION: A device for displaying pneumatic pressure of a tire(1) comprises an air injecting unit(2) formed in the tire to inject the air and keep the proper elasticity of the tire and a pneumatic pressure metering device(3) of which one end is embedded in the air injecting unit, mounted separately from the air injecting unit and connected with a colored display panel of an instrument panel of a driver's seat. The metering device is made of a buffering rubber(4) having an inserting unit(5) to be inserted and fixed to the tire. A rubber ring(8) is disposed to and a plunger(6) with a ground unit(7) is inserted and installed in the center of the buffering rubber. A transmitting unit(10) connected to a small battery(9) is combined and mounted to the side of the plunger by a waterproof cap(11). A spring(12) is interposed between the plunger and the transmitting unit. Ground switches(13,14) connected with an indication lamp installed to a display unit of the instrument panel are mounted to the outside of the plunger, respectively, connected to the transmitting unit and the battery, and turned on/off by the ground unit of the plunger.
