Abstract
Tire pressure is automatically checked when the motor vehicle is started. At the same time, the type of operation, either off-road operation or on-road operation, is detected. According to the inventive method, in the on-road operation of the motor vehicle, the speed of all four wheels is measured and it is made sure whether or not there is an inadmissible difference in wheel speed. If the wheel speeds do not differ, the theoretical tire pressure is determined. If the actual tire pressure differs from the theoretical pressure, the inflation or deflation valves of the tires are actuated until the theoretical value is achieved, thereby adjusting the theoretical value. If the wheel speeds differ, as for example, during the operation state of the off-road mode, the vehicle speed is measured and is compared with a threshold value.
