Abstract
In a tire design method, a numerical optimization is performed according to a basis vector process using an FEM model to obtain an optimal solution which optimizes an objective function for a tread pattern shape. A numerical optimization is performed according to an ECAT using the FEM model to obtain an optimal solution which optimizes the objective function for the tread pattern shape. Either of the calculations is executed first, and the optimal solution obtained at the first calculation is used as an initial shape when the other numerical optimization is performed.
