Abstract: A pressure ratio between a setpoint tire pressure and an actual tire pressure for a tire of a vehicle is ascertained by the following steps: Ascertaining a wheel load which is acting on the tire. Ascertaining a dynamic tire radius of the tire. Ascertaining the pressure ratio as a function of the wheel load and the dynamic tire radius.
