Classification: CPC B | IPC B

Claim 13:
14. 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; and
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; wherein
the temperature acquisition unit acquires the temperature value at a predetermined period length, and
the temperature acquisition unit acquires the temperature value of the first tire at a period length smaller than the predetermined period length 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 difference between the temperature of the first tire and the temperature of the second tire is greater than a predetermined threshold value.
