The invention belongs to the technical field of tire rolling resistance, and relates to a tire rolling resistance coefficient prediction method, which comprises the following steps: calculating to obtain rolling resistance coefficient calculation values of tires of different specifications according to tire size parameters, and calculating the rolling resistance coefficient of the tires of different specifications on the basis that the ratio of the rolling resistance coefficient calculation values of the tires of different specifications is equal to the ratio of the actual rolling resistance coefficients of the tires of different specifications. When the actual rolling resistance coefficient of the tire of any specification is known, the rolling resistance coefficients of the tires of other specifications can be obtained through the ratio. The rolling resistance coefficient of the tire is calculated by using the basic size parameters of the tire and is corrected according to different sizing materials and groove depths, and compared with an experimental method, the time and labor cost can be reduced, the calculation result can be quickly obtained, the working efficiency is improved, and the project period is shortened; compared with a simulation method, the method is simple and easy to operate, the result of the rolling resistance coefficient can be calculated without mastering simulation experience and mechanical knowledge for many years, the time is short, the cost is low, and the obtained result still has extremely high accuracy.
