Abstract：The study investigates the kinematic characteristic of the radial tire with a large section ratio (the section ratio is 1) with the continuous analytical elastic foundation modeling. A proposed tire model with a flexible belt on an elastic continuous stiffness foundation considering the coupled feature between the tire carcass and tire sidewall is investigated. The analytical multi-stiffness function of tire sidewall with a large flat ratio is researched with the pre-tension string and structural stiffness resulting from the sidewall deform. The influence on the radial stiffness, transfer function and modal frequency is discussed. The experimental and theoretical results indicate the following: (1) the radial segmented stiffness function of the curved sidewall is related to the inflation pressure, structural curvature, and material properties; (2) the analytical segmented sidewall model can be used to optimize the modal and transfer function of the tire.
