A tire trouble detection device detects occurrence of a trouble in a tire.
The tire trouble detection device comprises a detection unit which
detects a change of state of a layered composition portion arranged in
layers inside an outer sheath forming an outside surface of the tire, the
layered composition portion forming a frame of the tire. A determination
unit receives a result of the detection from the detection unit and
determines occurrence of a trouble of the layered composition portion
based on the received result of the detection.
