In the current work, a methodology is proposed to study the tyre static and dynamic behaviour to estimate its constituents properties based on the measured quasi-static responses of the tyre for certain specific loads. As a first step, a simplified tyre numerical model with standard rubber material properties is modelled that can substantively predict the necessary tyre static responses, i.e. radial, longitudinal and lateral stiffness. These responses are correlated with the physical tyre response that are measured using a kinematic and compliance (K&C) test rig in the laboratory. A Design of Experiments (DoE) study, followed by an optimisation process, is performed by sampling the material properties of the rubbers to simulate the FE model and match the tyre responses accurately. As a final step, the contribution of tyre individual constituent rubber material properties over the tyre modal behaviour is analysed.
