PROBLEM TO BE SOLVED: To improve a calculation efficiency in an analysis of a tire by a numerical value analysis method such as a finite element method (FEM), or the like. SOLUTION: A tire section model is formed (step 112), and elements (a belt or a ply) having in common a node on the model are set and each element is defined in piles (step 114, 116). The tire section model after performing duplicate definition of the elements (reinforcements) is developed as much as one circuit in the circumferential direction, to thereby form a three-dimensional (3D) model of the tire (step 118). Since a domain for performing element breakdown of a component (rubber) can be enlarged by defining the elements in piles, mesh can be set coarsely, and a calculation time can be shortened.
