The invention describes a method for temperature compensation of measured pressure values in a tire pressure control system of a vehicle, which is equipped with wheels with pneumatic tires in which a pressure sensor arranged below the tire obtains the pressure values and a temperature sensor arranged below the tire obtains temperature values and the measured pressure values are referred to a predefined reference temperature, giving due consideration to the known proportionality between the pressure and the temperature at a volume of air in the tire which is assumed to be constant. The invention provides that an offset of the temperature supplied by the temperature sensor from the mean air temperature prevailing in the tire is estimated for the temperatures measured at any time in the tire, and the currently measured temperature values are corrected using the estimated temperature offset as a correction value.
