PROBLEM TO BE SOLVED: To provide a simulation method for a tire capable of suppressing reduction of simulation efficiency.SOLUTION: The simulation method includes: a tire model creation step for creating a tire model that is a finite element model of a tire including an axle and a rim by dividing the tire into a finite number of multiple elements; a ground portion setting step for setting multiple ground portions in contact with a road surface on which the tire is traveled, in a circumferential direction of the tire; a deployment portion setting step for setting multiple deployment portions in contact with the multiple ground portions of the tire model on a virtual road surface simulating the road surface; a movement step for moving the virtual road surface around the tire model in such a manner that the multiple ground portions of the tire models are successively brought into contact with the deployment portions of the virtual road surface corresponding to the ground portions, in a state where rotations of the axle and the rim of the tire model are restricted; and an analysis step for analyzing characteristics of the tire based on the tire model in the movement step.SELECTED DRAWING: Figure 3
