To provide a tire model creation method, a tire model creation device and a program which can obtain an appropriate tire model even if a large shape change is given to a tire model.SOLUTION: A tire model creation method includes the steps of: calculating a movement amount on an outer side contour line onto an outer side contour line of a changed tire model of a nodal point on the outer side contour line of a reference tire model by using the reference tire model that is composed of elements that can be numerically analyzed by a computer and includes nodal point information, and information on the outer side contour line of the changed tire model after changing the shape of the reference tire model; setting a straight line that defines the thickness at each position of the reference tire model; calculating the movement amount on the outer side contour line of an intersection of the straight line and the outer side contour line of the reference tire model; setting the movement amount on the outer side contour line at the intersection as a movement amount to the nodal point of the reference tire model on the straight line; and creating the changed tire model by applying the movement amount to the nodal point on the straight line of the reference tire model.SELECTED DRAWING: Figure 7
