The invention provides an automobile tire inflation device. The automobile tire inflation device comprises a pressure limiting valve, a butt joint pipe, a gas outflow control valve, a three-way pipe, a pressure measurement system and a gas discharge switch. One end of the butt joint pipe is connected with the pressure limiting valve, and the other end of the butt joint pipe is connected with the gas outflow control valve. The gas outflow control valve comprises a gas outflow control valve body, a gas outflow control valve rod and a spring. A cavity is formed in the gas outflow control valve body. The pressure measurement system comprises a pressure measurement element, a switching switch, a pressure measurement circuit board, a pressure display screen and a power supply. A multifunctional gauge is arranged on the pressure limiting valve. The automobile tire inflation device has the beneficial effects that automobile tires can be inflated and pressure required by the tires can be accurately achieved under emergency situations; and the automobile tire inflation device is convenient to carry, safe and efficient to use and accurate in output nitrogen pressure.
