PROBLEM TO BE SOLVED: To provide: a method for analyzing tire action force using a finite element model of a tire, which is capable of precise and accurate simulation; and a method for analyzing tire vibration and tire noise using such a method. SOLUTION: The method for analyzing tire action force using a finite element model of a tire includes: a protrusion segmentation process of segmentalizing raised portions on a road into an assembly of protrusions; a first action calculation process of calculating the action that a tire receives from the protrusions when the tire runs over the raised portions; and a second action calculation process of, by adding for each protrusion the action as calculated in the first action calculation process, calculating the action that the tire receives from the raised portions.
