PROBLEM TO BE SOLVED: To provide the accuracy of simulation.SOLUTION: Provided is a creation method of a tire model 3 for analyzing a tire 2 with a computer 1. This creation method includes: a step P1 in which the tire 2 is modelized on the basis of a cross-sectional shape in a vulcanization mold 24 used in a vulcanization step, and the tire model 3 is set which includes a band ply model 30 obtained by modelizing a band ply 9A; and a residual stress setting step P3 in which deformation calculation is performed by defining the residual stress Si generated in the vulcanization step for each element Fi of the band ply model 30 of the tire model 3. |
