The object is to provide a tire condition monitoring system in which power consumption upon output of information by the tire side communication device can be reduced as compared with the conventional tire condition monitoring systems. According to the present inventive tire condition monitoring system 10, the tire side communication devices 20 superimpose detection information on the electromagnetic waves, delivering the electromagnetic waves as surface waves of the tire wheel 12 and vehicle body 15. Accordingly the power comsumption in output of information can be reduced as compared with the conventional tire condition monitoring systems. Consequently, the size of the microcell 30 used in the tire side communication device 20 can be downsized and the life of the microcell 30 can be longer. More specifically, the tire condition monitoring system 10 of the embodiment consumes -10 dBm (0.1 mW) at the time of information output although a conventional system consumes 3 dBm (2 mW). Thus, the power consumption in inforrmation output can be reduced to one twentieth of that of the conventional system.
