To create a detailed model of a surface and perform analysis with high efficiency.SOLUTION: A tire model creating method for creating a model of a tire surface for use in fluid analysis by using a computer, includes: a step of creating a deformation analysis tire model having a pattern model and a case model in which the number of divisions in a circumferential direction is less than that in the pattern model; a shape analyzing step of performing shape analysis of the deformation analysis tire model; a surface shape model creating step of acquiring, as a surface shape model, a surface shape of the post-shape analysis deformation analysis tire model, a boundary correcting step of shaping a region including a boundary between the pattern model and the case model of the surface shape model, into a shape closed by a triangular element, and a step of creating a tire periphery space model in which a space is disposed around the surface shape model with the boundary set along the outer shape of the corrected surface shape model.SELECTED DRAWING: Figure 3
