Abstract
An air inflation system for attachment to rotating wheels having outwardly directed studs for inflating a tire thereon. An elongate support is threadably attached to a stud on the wheel for supporting the support. An adjustable arm is rotatably connected to the support and in turn supports a rotatable air coupling. An air supply line is connected to the coupling and an outlet line from the coupling supplies air to a tire on the wheel.
