Valve, tire, rim and wheel

The invention is based on a valve with a valve body having: an air duct which penetrates the valve body, in particular in the axial direction, and a valve foot which is formed, in particular in one piece, with the valve body, on an end of the valve body which is proximal with respect to a rim edge in the installed position, wherein a distal end of the valve body is provided to engage through a valve hole in the rim edge, and the valve foot is provided for arrangement on a tyre-side side of the rim edge. In order to permit easier removal of the valve, in particular even on a side of the rim edge facing away from a tyre, the invention provides for the valve foot to be provided to engage through the valve hole, and for a securing element which is separate from the valve body and which projects over the valve foot, in particular in the radial direction, to be arranged at the proximal end, said securing element being provided for arrangement on a tyre-side side of the rim edge.
