PROBLEM TO BE SOLVED: To provide a tire information measuring system capable of switching the measurement frequency of tire-related information between normal travel and environmental change, and thereby contributing to appropriate situation determination.SOLUTION: A tire information measuring system includes: a first power generator and a second power generator arranged on at least one of a plurality of tires attached to a vehicle, and generating electric power in response to tire driving; power storage means connected to the second power generator for storing the electric power generated by the second power generator; a tire information sensor measuring information on the tires; a changeover switch for selectively switching continuity of the tire information sensor to the first power generator or a secondary battery; and a control unit controlling the changeover switch in response to a sensor output value that is a value output from the tire information sensor. |
