A device for detecting a pressure change in a tire includes a first temperature sensor located outside the tire being configured to produce a first temperature signal indicative of a first temperature, an input apparatus configured to receive the first temperature signal from the first temperatures sensor, and to receive a second temperature signal from a second temperature sensor being indicative of a second temperature, and to receive a tire pressure signal from a tire pressure sensor being indicative of a tire pressure of the tire, and a processor configured to output an evaluation signal including information about a change of tire pressure based on the pressure signal and based on the first temperature signal and the second temperature signal. The processor is configured to evaluate the pressure signal only if a temperature difference between the first temperature and the second temperature is smaller than a predefined limit value.
