PROBLEM TO BE SOLVED: To evaluate a vibration performance caused by a specific condition.SOLUTION: A vibration performance evaluation method for a tire using a computer and a simulation device for the tire are provided. The evaluation method includes: a step S1 of inputting to the computer, at least one tire model formed by modeling the tire using the finite number of factors,; a step S2 of inputting to the computer, at least one road surface model formed by modeling a road surface using the finite number of factors; a step S3 of rolling the tire model on the road surface model based on at least two predefined conditions different from each other and calculating a physical quantity relating to vibrations using the tire model regarding each of the conditions; and a step of calculating a differential between the physical quantities regarding the conditions.SELECTED DRAWING: Figure 3
