An air inflation system (20) for attachment to rotating wheels (12) having outwardly directed studs (16) for inflating a tire (14) thereon. An elongate support (22) is threadably attached to a stud (16) on the wheel for supporting the support. An adjustable arm (24) is rotatably connected to the support and in turn supports a rotatable air coupling (26). An air supply line (64) is connected to the coupling (26) and an outlet line (30) from the coupling supplies air to a tire on the wheel.
