Abstract: As the only contact part between the vehicle and road surface, the rolling resistance of tire directly affects the economy and emission performances of vehicle. In order to reduce the tire rolling resistance under composite working conditions, a 205/55R16 tire is taken as the research object. Hysteresis energy loss is selected as the evaluation index of rolling resistance. The influences of structural parameters in the crown area and non-crown area on the rolling resistance under cornering, roll, traction and braking conditions are analyzed. Furthermore, the structural parameters significantly related to the rolling resistance are screened out through correlation analysis, and the Kriging approximation model combined with the multi-island genetic algorithm are used to optimize those parameters. The results show that the rolling resistance of the optimized tire is reduced by 6.12% under composite working conditions. The relevant research provides a reference for reducing the rolling resistance of tires.
