A simulation method is proposed to predict temperature rise within a dynamic rolling tire. The friction heat from tire-road contact and the internal heat generated by hysteresis loss caused by rubber deformation are considered in the simulation model. A systematic process was developed to calculate the heat generation rate by using dissipated energy, and it was applied to the simulation model by establishing user subroutines. An axial tensile test was conducted for the rubber specimen, and the obtained stress-strain curve was applied to the simulation model based on the first-invariant Marlow model. The reliability of the simulation method was verified by comparing the tensile simulation and test results. A simplified 3D finite element tire model was developed, and simulations were performed in dynamic rolling conditions. Heat was generated because of friction and internal deformation. The temperature distribution within the tire, which was derived using the model, indicates that the proposed simulation method is reliable.
