Claim 3:
4. The tire system according to claim 1, wherein:
the vehicle-body-side system further includes
a vehicle communication device configured to transmit the data related to the road surface state to a communication center that collects road information and acquire data related to a road surface state of road on which the vehicle is going to travel from the communication center, and
a position information acquisition unit configured to acquire present position information of the vehicle;

when transmitting the present position information to the communication center through the vehicle communication device and receiving a request signal that requests the data related to the road surface state transmitted from the communication center, the vehicle-body-side system transmits a request signal indicating that the detection target is the road surface state to the tire-side device through the second data communication unit; and
when the request signal indicating that the detection target is the road surface state is transmitted, the tire-side device generates the data related to the road surface state even not in the normal mode and transmits the data to the vehicle-body-side system through the first data communication unit.
