PURPOSE: A pneumatic pressure charging apparatus of a tire is provided to improve the driving stability by supplementing the pneumatic pressure according to the regulation if the pneumatic pressure of a tire is less than the regulated value. CONSTITUTION: A pneumatic pressure charging apparatus of a tire is composed of a compressor(1), a valve sensor(2a), and a pneumatic pressure charging unit. The compressor is formed in an air suspension of a vehicle. The valve sensor senses the pneumatic pressure of a tire. The pneumatic pressure charging unit interconnects the compressor and the valve sensor. The pneumatic pressure charging unit informs a driver of the tire condition if the pneumatic pressure of the tire is less than the regulated value and supplements the pneumatic pressure of the tire.
