To provide a tire state detection system, a tire state detection method and a tire state detection program with which, even when an acceleration sensor is attached to the inside face of tread of a tire, it is possible to detect the tire state without being affected by grounding to earth of a tread portion that corresponds to the position where the acceleration sensor is attached.SOLUTION: A processing device 120 of a tire state detection system 100 comprises: an acceleration data acquisition unit 123 for acquiring acceleration data detected by an acceleration sensor 111 for each prescribed acquisition interval; an acceleration data extraction unit 125 for extracting at least maximum acceleration data that indicates maximum acceleration and intermediate acceleration data that indicates intermediate acceleration, with minimum acceleration data that indicates minimum acceleration excluded, out of three or more sequentially acquired acceleration data; and a computation unit 127 for executing a computation in which the extracted intermediate acceleration data is used.SELECTED DRAWING: Figure 2
