ABSTRACT:
The present invention relates to a process and device for the automatic regulation of the internal pressure in a pneumatic tire characterized in that the air is forced into the pneumatic chamber of a tire by the centrifugal force generated by the revolution of the wheel, and the pressure inside said pneumatic chamber can thereby be automatically changed in dependence on the speed of rotation of the wheel.
