PROBLEM TO BE SOLVED: To detect temperature inside a tire with simple, small, lightweight, and inexpensive structure. SOLUTION: Temperature detecting means 11-19 are provided on an inner surface of an inside of a tire radial direction facing a tread part 2 and a side wall part 3 of the tire 1. The respective temperature detecting means 11-19 have a plurality of temperature detecting members having different melting points, such as a low melting point solder alloy or low melting point solder having about 60-300°C m.p. A vehicle in which the tire 1 is installed is travelled, and after travelling is finished, whether or not the low melting point solder in the respective temperature detecting means 11-19 has melted is examined. For example, when the low melting point solder having 60°C and 70°C m.p. melts and the low melting point solder having 80°C, 90°C, etc. m.p. does not melt, it is recognized that the temperature in the tire 1 has risen about 70°C to 80°C during traveling.
