Tires are critical components for automobile and aircraft applications from vehicle dynamics, safety and overall performance perspective. The work in this paper discusses finite lement analysis of tire deformation subjected to 3.5 bar pressure using ABAQUS tool. The hyperelastic material models viz Neo-Hookean and Mooney-Rivlin are used to capture the nonlinear behavior of tire. The simulation focuses on investigation of key tire parameters like tread width, tread pattern, and sidewall thickness in order to assess their impact on stress distribution and deformation. Stress concentrations (320 MPa) were observed in high-stress regions, such as the bead wire, belt edges, and sidewalls, which are imporatnt for maintaining structural integrity. Belt reinforcement were modelled using rebar layer function. This enhanced tread stability by distributing stress and reducing deformation in high stress zones. The results obtained from finite element simulation showed that the Mooney-Rivlin model gives more accuracy in predicting stress-strain behavior as compared to the Neo-Hookean model. Further contact pressure was observed varying across the tread region providing insights into tire-road interactions. The precise material modeling and reinforcement strategies found to be imporatnt for improving tire durability, safety, and performance.
