Abstract
A pressure deviation between a setpoint tire pressure and an actual tire pressure for a tire of a vehicle is determined by the following steps:
Ascertaining a wheel load for the tire.
Ascertaining a dynamic tire radius of the tire.
Determining the pressure deviation as a function of the wheel load and the dynamic tire radius.
