• means fitted on each of the road wheels of said vehicle for regulating the inflation pressure of said pneumatic tires mounted on said wheels, said pressure regulating means including deflation means and inflation means in fluid communication with the interior of said tires, and RF signal receiving means associated with means for actuating selectively either said deflation means or said inflation means;
• RF signal transmitting means on said vehicle at a location proximate each of said wheels for providing command signals to said signal receiving means for activating said tire inflation-pressure regulating means on said wheels;
• control means in said vehicle operable manually by an occupant thereof and connected to said RF signal transmitting means for providing command inputs for selectively deflating or inflating said tires.
