Tire model is one of the most important components of vehicle dynamic simulation because it is responsible for calculating major external forces and moments acting on a vehicle. The conventional modeling approach relies on empirical formula, hence, the resulting model cannot account for the effect of temperature and inflation pressure changes that occur during handling test maneuvers. In this study, a physical tire model is proposed based on the brush model with flexible carcass. Its parameters are determined by using indoor tire force and moment measurements along with footprint data. The model parameters for tires with different sizes and design specifications are obtained at several temperature and inflation pressure conditions. Based on the results, the parameters are modeled as functions of tire tread temperature and inflation pressure.
