In this paper, a new model for the speed dependency of friction is developed. The model formulation is based on existing knowledge in tribology, especially in lubricated-friction research. The proposed mathematical formula is found to be a generalization of the well-known PIARC model. Fitting of the new model to experimental data is shown. Attempts are made to related the model constants to measurable parameters such as surface macro- and microtexture, wheel slip, tire tread depth and water thickness.
