Disclosed is a method for operating a device used for monitoring and signaling in a wireless manner the pressure or a change in pressure of tires on vehicle wheels, hereafter called wheel electronics. According to the inventive method, the existing pressure in the tire is measured by generating electric pressure gauging signals, and a signal providing information on the pressure or a change in pressure is then transmitted. Said information signal is received by a receiver which is arranged in or at the vehicle. The wheel electronics are put into a first operating condition by a first control signal which is transmitted in a wireless manner from outside the wheel electronics. In said first operating condition, the pressure or a change in pressure is measured and is transmitted as a result of receiving an inquiry signal which is generated outside the wheel electronics and is transmitted thereto in a wireless manner. The wheel electronics are placed in a second operating condition if the wheel electronics do not receive another inquiry signal within a predefined period of time after receiving the first inquiry signal. In said second operating condition, the pressure or a change in pressure is repeatedly measured and is transmitted at a set or variable transmission rate which is formed in the wheel electronics for said second operating condition.
