Abstract
The invention relates to a method for monitoring the air pressure of a tire of a motor vehicle with a tire pressure control system. The invention further relates to a motor vehicle having a tire pressure control system with which the method can be carried out. The tire pressure control system includes tire pressure control devices (4a to 4d) on each of the wheels (2a to 2d), which transmit to a central unit, at regular intervals, a data transmission which contains, inter alia, the air pressure measured in the tires. The central unit generates a warning signal when the determined air pressure deviates by more than a pregiven amount from the stored air pressure. The motor vehicle contains a second tire pressure control system which operates independently of the first tire pressure control system and monitors the air pressure in the tires of the motor vehicle at least when a transmission pause, which is too long, occurs between two data transmissions of one of the tire pressure control devices (4a to 4d).
