PROBLEM TO BE SOLVED: To provide a tire analysis system and a tire analysis method for measuring change in the surface distortion of a tire using an inexpensive imaging apparatus. SOLUTION: The tire analysis system 1 performs a behavior analysis of a tire by measuring the change in the tire shape and the change in the surface distortion of the tire when predetermined test conditions are input. The tire analysis system 1 includes a plurality of cameras 31, 31 for taking images of a plurality of analytical lattice planes S, arranged along the circumferential direction of the tire on a part of the tire surface, from mutually different directions simultaneously, and a processing device 4 for calculating the three dimensional coordinate of the analytical lattice plane S based on the image data obtained from the cameras 31, 31, and for calculating the change in the tire surface distortion based on this three dimensional coordinate. Further, the cameras 31, 31 take the image of the analytical lattice plane S when the analytical lattice plane S comes to a predetermined image taking position by the rotation of the tire 10.
