Tires are the primary components that directly provide the mechanical grip for vehicles. Therefore, understanding tire behavior is of significant importance for improving vehicle performance. However, the tire’s conventional round shape, its fluid–structure interaction, and the thermodynamics environment make the research challenging. In this research, we study the deformation characteristics of an actual tire using steady-state analysis. The tire we study has a simple longitudinal-tread geometry. The material is mainly rubber, and several reinforcements are inserted. It is subject to internal pressure and contacting the road. We model the rubber with solid and the reinforcements using shell formulations. We start with non-uniform rational B-splines for discretization, and to ensure higher continuity, we apply T-splines. Employing these methods, we conduct a contact analysis to ascertain tire deformation
