Abstract: A tire deterioration state prediction method for predicting, by a computer, the deterioration state of a tire using a tire model configured from multiple elements comprises an information acquisition step for acquiring information relating to a use environment, which includes the pressure history and the temperature history in an air chamber during tire use, and the history of load acting on the tire, and information relating to the tire characteristics, including the material characteristics of members configuring the tire; a temperature history calculation step for calculating, for each element, the temperature history of the tire on the basis of the information acquired in the information acquisition step; an oxygen concentration history calculation step for calculating, for each element, the oxygen concentration history on the basis of the information and the temperature history of each element; and a tire deterioration state evaluation step for evaluating the deterioration state of the tire on the basis

Abstract: This tire management device enables tire management for equalizing the use period of tires mounted on a vehicle, and is provided with a deterioration state prediction unit which, for each mounting position, predicts the deterioration tendency and the deterioration state of the tires mounted on the vehicle; a usable period prediction unit which, for each tire mounting position, predicts the usable period of the tire on the basis of the deterioration tendency and deterioration state predicted by the deterioration state prediction unit; and a mounting position planning unit which, setting the deterioration tendency of each tire predicted by the deterioration state prediction unit as a mounting position deterioration characteristic of each mounting position of a tire in the vehicle, creates, on the basis of said mounting position deterioration characteristics and the usable periods of the tires predicted by the usable period prediction unit, a modification proposal for changing the mounting positions of the tires
