An apparatus for inflation and deflation of tires of an automobile is disclosed. The apparatus includes an air pressure source to store the air and a valve bank having a solenoid valve for each tire of the automobile to control the flow of air from the air pressure source based on a control signal received from inflation and deflation system. Further, the apparatus includes an air control unit installed on each tire to receive air from the air pressure source via the corresponding solenoid valve. The air control unit has a central pipe to receive air pressure to press a valve stem of the tire and a surrounding pipe to facilitate ingress and egress of air into the tire and out of the tire for inflation and deflation, respectively.
