Railway wheels suffer wear, irregular wear patterns develop on their surfaces. Travel comfort and safety are reduced and expensive profiling of the wheels becomes necessary. A common explanation is that initial out‐of‐roundnesses increase because of the oscillations they cause. We develop a model to study these mechanisms. Particularly we take into account the evolution of out‐of‐roundnesses in axial and azimuthal direction on the wheel treads and outline the structure of the governing equations.
