When a road surface condition does not change, road surface data is transmitted by a tire-mounted sensor at a rate of once every time a tire rotates a plurality of times, in order to reduce the power consumption from a power source. Further, when the road surface condition changes, the road surface data is transmitted by the tire-mounted sensor with a transmission interval that is shorter than when the road surface condition does not change. In this way, reducing the amount of road surface data that is transmitted when the road surface condition does not change makes it possible to reduce the amount of power required for data transmission. Further, using a transmission interval that is shorter when the road surface condition changes than when the road surface condition does not change makes it possible for changes in the road surface condition to be conveyed rapidly to a vehicle body side system.
