The present invention discloses a tire pressure-limiting air nozzle capable of operating according to a pure physical principle and is free of self energy consumption. The tire pressure-limiting air nozzle is mounted on a wheel hub, is fixed by a fastening nut and is used for enabling a seal ring and the wheel hub to form airtightness; by virtue of rotation of a pressure adjusting rod, the pressure of a pressure adjusting nut and the pressure of a spring reach the required air pressure value, thereby completing the pressure-limiting setting; the pressure adjusting rod is propped when injecting air into an air chamber; the pressure adjusting rod is used for propping and opening a valve cover along the force, so that the air enters the air chamber; when air pressure in the air chamber exceeds the set air pressure value, air pressure in the tire air chamber is applied to a sealing gasket; the sealing gasket is pressed and deformed by air pressure in the air chamber to push a pressure releasing valve to move in the direction of the pressure adjusting rod; meanwhile, the pressure adjusting rod props against the valve cover, thereby discharging the air; when the air pressure is released to the set air pressure, the sealing gasket loses overpressure and restores to the normal position; the valve cover is used for pressing the sealing gasket to form airtightness and finish the pressure-limiting action.
