PROBLEM TO BE SOLVED: To obtain a tire cross sectional shape in a usage state.SOLUTION: A tire model 70 for reproducing a tire cross sectional shape is created and a rim model 50 for reproducing a cross sectional shape of a part of a rim which contacts to a tire is created. The rim model 50 is disposed on an initial position which is off to a tire radial direction K and a tire axial direction J with respect to a regular rim position so that the tire model 70 contacts to the rim model 50 by only a bead toe 72 and the bead toe 72 contacts to the rim model 50 with fine overlapping which is equal to or less than a prescribed overlapping. With contact analysis of the tire model 70 and the rim model 50, the rim model 50 is displaced to the regular rim position from the initial position and while internal pressure is filled in the tire model 70 displaced to the regular rim position, deformation calculation of the tire model 70 is performed. |
