PROBLEM TO BE SOLVED: To provide a tire management device capable of managing tire quality of a portion other than a tread part of the tire. SOLUTION: The tire management device operates forces Tf, Tr in a vehicle longitudinal direction and forces Yf, Yr in a vehicle lateral direction received by the respective tires T in every tire T based on distances Lf, Lr in a longitudinal direction from gravity center positions G of the respective tires, i.e., a specification value of the vehicle 1, inertia moment I of the vehicle 1, weight M of the vehicle 1, loads Mf, Mr applied to the respective tires T respectively, vertical acceleration Gt, i.e., the state amount of the vehicle, lateral acceleration Gy and yaw angular acceleration rdt. Since the operation result is stored in a transponder 10 of the corresponding tire T, the operation result stored in the transponder 10 is read later, thereby a history of the force received by the tread part of the tire T and the portion other than the tread part can be easily and certainly confirmed.
