A method for controlling motion of a heavy-duty vehicle (100), the method comprising obtaining input data related to one or more tyre parameters of a tyre (150, 160, 170) on the heavy-duty vehicle (100), estimating at least part of the one or more tyre parameters based on the input data, configuring a tyre model, wherein the tyre model defines a relationship between tyre wear rate and vehicle motion state, wherein the tyre model is parameterized by the one or more tyre parameters, estimating vehicle motion state, and controlling motion of the heavy-duty vehicle based on the tyre model and on the vehicle motion state.
