PURPOSE: A vehicle tire pressure controlling system is provided to increase fuel efficiency by controlling the pneumatic pressure of a tire according to the change of car driving environment. CONSTITUTION: A vehicle tire pressure controlling system comprises a compressed air tank(100), an exhaust tank(200), a connection part, a sensor unit, a controller, and a power supply unit. The compressed air tank is formed between rims of a vehicle wheel and is integrated with one side of the outer surface of a hub shaft along the outer circumference thereof. A compressed air inlet(110) is formed on one side of the compressed air tank. The exhaust tank is integrated with the other side of the outer surface of the hub shaft along the outer circumference thereof. The connection part is connected through pipes equipped with the compressed air tank and a motor-operated valve. The sensor unit is installed between the rim of the vehicle wheel and a pneumatic tube of the tire. The controller selectively transmits signals for controlling the opening/closing of the motor-operated valve to each motor-operated valve. The power supply unit is projected from the outside of the vehicle wheel.
