Classification: CPC B | IPC B

Claim 0:
1. A tire failure prediction system, comprising;
first and second temperature sensors configured to detect a temperature value of each of a first tire and a second tire that are mounted on a traveling vehicle;
a temperature acquisition unit configured to acquire the temperature values respectively detected by the first and second temperature sensors;
a determination unit configured to make a determination, based on the temperature values acquired by the temperature acquisition unit, of a possibility of failure of the first and second tires,
the vehicle comprising axles on which the tires are mounted,
the first tire and the second tire being mounted on an identical axle of the vehicle,
a mounting position of the first tire and a mounting position of the second tire being symmetrical positions on the identical axle, and
the determination unit making a determination that the first tire has a possibility of failure in a case where the temperature value of the first tire acquired by the temperature acquisition unit is greater than a predetermined threshold value, and a temperature difference corresponding to a difference between the temperature value of the first tire and the temperature value of the second tire acquired by the temperature acquisition unit is greater than a predetermined first temperature threshold value;
first and second air pressure sensors configured to detect air pressure values of inner portions of the first tire and the second tire, the first tire and the second tire being pneumatic tires; and
an air pressure acquisition unit acquiring the air pressure values respectively detected by the first and second air pressure sensors, wherein
the determination unit makes the determination by using a second temperature threshold value that is higher than the first temperature threshold value in a case where an air pressure difference corresponding to a difference between the air pressure value of the first tire and the air pressure value of the second tire acquired by the air pressure acquisition unit is greater than a predetermined threshold value.
