A method for operating a tire pressure monitoring unit for monitoring pneumatic tires of a vehicle includes where a pressure measurement is taken at regular intervals using a pressure sensor and the pressure information is transmitted wirelessly at larger intervals by a transmitter. A control unit checks whether a pressure change exceeding a threshold value has occurred, and, if so, pressure measurements are taken at shortened intervals and the transmission activity is increased. The control unit uses a first threshold value for the pressure change in the case of a stationary vehicle and uses a second threshold value, which differs from the first threshold value, for the pressure change in the case of a moving vehicle. The control unit, by evaluating a signal of an acceleration sensor of the tire pressure monitoring unit, establishes whether the first threshold value or the second threshold value is used.
