To provide a tire valve operation switching system that can easily switch the operation of a tire valve.

The tire valve operation switching system 6 switches the operation of the tire valve 3 that is mounted on each tire 2 and can wirelessly transmit a detection signal Stp of the tire air pressure. The tire valve operation switching system 6 includes: door LF wave transmitters 13 to 17 preliminarily mounted on a vehicle 1 and capable of transmitting a radio wave of the same frequency as the radio wave that can be received by the tire valve 3; a mode switching operation detection unit 11b detecting a trigger input by the vehicle 1 as a request to switch the operation of the tire valve 3; and a transmission control unit 11c, which controls, when the trigger is detected by the mode switching operation detection unit 11b, the door LF wave transmitters 13 to 17 to transmit an operation signal to the tire valve 3, the operation signal for setting the operations of the tire valve 3 in a range narrower than the range when the door LF wave transmitters 13 to 17 transmit a request signal Srq as the main function itself.
