Abstract
A tire inflating system has the tire inflating source connected through the hub to the wheel by a pair of aligned axial holes in the hub and wheel. A movable tube piece in the axial hole in the wheel is formed with side openings and is engaged by a sealing ring in the axial hole in the wheel which also receives a seal pressed by a spring toward a mouth of that hole. The tube piece can hold the seal in an open position until the wheel is separated from the hub.
