A vehicle mounted tire changing system is provided of the type having a hydraulic jack system connected to a vehicle for lifting a portion of the vehicle relative to the supporting terrain and a pneumatic system carried by the vehicle for connecting air operated tools. The vehicle mounted tire changing system comprises: a plurality of hydraulic jacks mounted to a vehicle in a substantially vertical orientation relative to the supporting terrain; a hydraulic power unit coupled in communication with the hydraulic jacks for providing a hydraulic fluid under pressure to actuate the hydraulic jacks; a hydraulic manifold having valve assemblies coupled in fluid communication between the jacks and the hydraulic power means; a control unit for selectively activating the valve assemblies; an air compressor electrically connected to a battery via a switch for selectively operating the air compressor; a pair of air hoses each having a first end in fluid communication with the air compressor and a second end carrying an air tool connector for operably connecting air operated tools thereto, the connectors are connected to opposite sides of the vehicle. The hydraulic jack having an outer cylinder for mounting to the vehicle, an inner rod having a distal end, the inner rod operable to be hydraulically extended from and retracted into the outer cylinder and a base connected to the distal end of the inner rod.
