To provide a simulation method and the like that can calculate a physical quantity acting on a tire in a short time.SOLUTION: The present invention relates to a tire simulation method and the like. The method includes: a step S1 that inputs a tire model; a step S3 that inputs a first condition including a characteristic of a tire and a condition of loading the tire to a vehicle; and a step S4 that inputs a first vehicle model modeling the vehicle having the tire loaded in the first condition. Further, the method includes: a step S5 that acquires first time-series data identifying a running state of the tire in time-series; a step S6 that acquires second time-series data on a physical quantity of the tire model on the basis of the first time-series data; a step S7 that acquires a function indicative of a relationship between the physical quantity of the tire model and the running state of the tire; a step S8 that sets a second condition; a step S9 that sets a second vehicle model on the basis of the second condition; a step S10 that identifies a running state in the second vehicle model; and a step S11 that substitutes the running state in the second vehicle model for the function, and calculates a physical quantity in the second condition.SELECTED DRAWING: Figure 2
