To provide a wear amount estimation system, an arithmetic model creation system, and a wear amount estimation method that can improve accuracy of estimating an amount of wear of a tire.SOLUTION: A wear amount estimation system 100 comprises: a vehicle information acquisition unit 12; a road surface state estimation unit 13; and a wear amount calculation unit 15. The vehicle information acquisition unit 12 acquires information including a movable load of a vehicle and a travel distance. The road surface state estimation unit 13 estimates a road surface state related to a road surface with which a tire 7 is in contact during the travel of the vehicle. The wear amount calculation unit 15 has an arithmetic model 15a that calculates an amount of wear of the tire 7 on the basis of input information, and inputs the information acquired by the vehicle information acquisition unit 12 and the road surface state estimated by the road surface state estimation unit 13 to the arithmetic model 15a to calculate the amount of wear of the tire 7.SELECTED DRAWING: Figure 1
