Abstract: An arithmetic model generation system includes a tire information acquisition unit, a position information acquisition unit, a wear amount calculator, and an arithmetic model update unit. The tire information acquisition unit acquires tire data including a temperature and pressure of a tire. The position information acquisition unit acquires position data for a vehicle on which the tire is mounted. The wear amount calculator includes an arithmetic model that generates an estimated wear amount of at least one groove of the tire, the wear amount calculator calculating the estimated wear amount of at least one groove of the tire by using the arithmetic model by inputting the tire data and the position data. The arithmetic model update unit updates the arithmetic model based on a wear amount measured by a tire measurement device external to the vehicle and the estimated wear amount.
