PROBLEM TO BE SOLVED: To provide a tire temperature detection device capable of directly detecting the temperature of specific part of a tire and early finding of temperature anomaly leading to a tire failure. SOLUTION: By using a tire temperature detection device provided with a flexible magnet which is stuck on tire inner surface and lowers its magnetism when the temperature rises, magnetic sensors distributed in a certain circumferential positions on the tire and a sensor attaching tool for attaching the magnetic sensors on wheels, The magnetic field from the flexible magnet is detected with the magnetic sensors and temperature of a tire part where the flexible magnet is pasted is directly measured.
