A method and a device for determining loads on vehicle's wheels, each with a tire, is disclosed. A deformation measured value and a pressure measured value for each tire, and at least one acceleration measured value for the vehicle are detected. For the respective wheels, dynamic wheel loads are calculated according to a first model and static wheel loads are calculated according to a second model. The second model comprises at least one model parameter calculated by statistical analysis of the calculated dynamic wheel loads, the calculated static wheel loads, and the detected at least one acceleration measured value. The at least one acceleration measured value is redetected and the dynamic wheel loads are recalculated from the previously calculated static wheel loads and the at least one detected acceleration measured value according to the second model using the previously calculated at least one model parameter of the second model.
