Abstract: As one of the tire mechanical properties, the steady rolling resistance of automobile tire exerts significant impacts on the power performance, fuel economy, braking performance, handling stability and tire lifespan. In this paper, the mechanism of tire rolling resistance is described, and the experimental measurement, numerical simulation and theoretical calculation methods of tire rolling resistance are summarized. Then, the influence of wheel structure parameters and material properties on tire rolling resistance is analyzed. Finally, the technical challenges and development trend of tire rolling resistance research are presented. This paper may provide some reference for the research of tire rolling resistance.
