PROBLEM TO BE SOLVED: To suppress an increase in calculation time in tire simulation.;SOLUTION: A computer creates a first tire model ununiform in a circumferential direction based on a pneumatic tire to be evaluated, and a second tire model actually ununiform in the circumferential direction based on the pneumatic tire to be evaluated (step S12). The computer executes analysis of contact of the second tire model to obtain displacement of joints of the second tire model (step S14). The computer imparts, to the first tire model, rotation information indicating the change in joints in time which is obtained by converting the circumferential position of the joints of the second tire model into time to obtain the rolling shape of the first tire model (steps S16, S18). The computer creates a spatial model in which a region including a region contacting like a contacting shape is divided into a plurality of elements (step S20).;COPYRIGHT: (C)2012,JPO&INPIT
