PROBLEM TO BE SOLVED: To provide a tire portion temperature prediction system and tire portion temperature prediction method that can accurately obtain a temperature at a portion high in possibility of failure occurrence.SOLUTION: A tire portion temperature prediction system comprises: a temperature measurement unit that measures a temperature of a specific position of a tire; and a temperature conversion unit that converts the temperature of the specific position of the tire measured by the temperature measurement unit into a temperature of at least any portion of a part right above a tire width direction end part of the most outer side belt layer in a tire radial direction of a tread part, a shoulder part and a bead part. The temperature conversion unit is configured to implement temperature conversion on the basis of at least any condition of a condition 1: upon temperature prediction of the part of the tread part, the temperature conversion is implemented based on an amount of residual groove of the tire, a condition 2: upon temperature prediction of the shoulder part, the temperature conversion is implemented based on a travelling speed at which the tire is used; and a condition 3: upon temperature conversion of the bead part, a constant is added to the measured temperature at the specific position to thereby implement the temperature conversion.SELECTED DRAWING: None
