ABSTRACT:
A vehicle wheel that includes a valve which has a check device, with the wheel being intended for use with a pneumatic tire that even when operating as a tire which is flat or has otherwise lost pressure permits great distances to be covered at a reduced speed. To prevent misuse of the tire, in other words reinflation of a tire subsequent to flat-tire operation and before the tire has been checked for leaks, the valve is provided with a mechanism that prevents such misuse. This mechanism is pneumatically disposed in series with the check device and is installed in an open position and in such a way that it changes over into a closed position upon commencement of a flat-tire operation, with a special tool and/or special replacement parts being required in order to reestablish the open position of the mechanism.
