TIRE TEMPERATURE PREDICTION SYSTEM, TIRE TEMPERATURE PREDICTION PROGRAM, AND TIRE TEMPERATURE PREDICTION METHOD

The present invention is provided with a time-sequential load data acquisition unit that acquires data on a load of a predetermined loaded item in a time-sequential manner regarding a loading vehicle capable of loading the predetermined loaded item; a unit period setting unit that sets predetermined unit periods of which it is possible to change lengths according to a change in the load; a data division unit that divides time-sequential load data on the load of the loaded item by separating the time-sequential load data according to the unit periods; a representative value calculation unit that calculates respective representative values for each piece of divided data of the time-sequential load data divided by the data division unit; and a tire temperature prediction unit that predicts a temperature of tires mounted on the loading vehicle, at a specific time point, based on the respective representative values.
