PROBLEM TO BE SOLVED: To provide a tire information acquisition system capable of reducing manpower, time, and cost induced by acquiring tire information such as a tire internal pressure and the temperature in the tire, and capable of acquiring the tire information without causing radio interference even for a vehicle whose rear wheels are dual tires. SOLUTION: Sensor modules 3 (SM1-SM6) are mounted on respective wheels 4 of a vehicle 6. Two antennas 1a, 1b which are arranged in parallel to a traveling direction of the vehicle so that a spacing becomes a distance of 1/2 rotation of the wheel are provided, respectively, at both sides of a path by which the vehicle 6 passes. The vehicle 6 passes between the antennas 1a, 1b provided at one side of the path and the antennas 1a, 1b provided at the other side of the path at low speed, and thus, measured data of the tire status amount transmitted from the sensor modules 3 (SM1-SM6) with radio signals is received by the antennas 1a, 1b at both sides.
