Abstract
A motor vehicle with twin tires which includes one tire with a winter tread and a further tire with a summer tread arranged on a common rim. Each tire is provided with a device for the air pressure regulation for achieving a selective pressure decrease and increase. The device for the air pressure regulation is connected with a device for the air pressure control by way of a common control unit. Actuating switches influencing the control unit serve for the mutually matched pressure adjustment of the tires for the summer and winter operation.
