Abstract: The use of finite element models has been a great ally in product development, especially in the automotive industry in order to predict and obtain product improvements, in the case of this paper focused on tyre development. This paper describes a finite element model, from the elaboration of the tyre computer-aided design model up to the tyre service conditions for a static analysis of the tyre and with special attention to the effect of changing the geometry of the carcass from mono-ply to bi-ply and the way that it affects directly the structure stiffness of the tyre. The model allows a greater number of analyses to be carried out in less time than the development and testing of one industrial prototype. Descriptions of the model structure and construction procedure are provided, including inflation and footprint analyses and lateral, longitudinal and vertical stiffness.
