Abstract: A tire maintenance support system includes a wear progress degree acquisition portion that acquires a wear progress degree of each of a tread and a side portion in each mount position, a wear amount calculation portion that calculates a predicted wear amount, which is a wear amount of each of the tread and the side portion in each mount position until maintenance timing when maintenance of the vehicle is performed, based on the acquired wear progress degree, and a re-tread member selection portion and a re-side member selection portion that select a thickness of a member to be needed when at least one of the tread and the side portion is replaced, based on the calculated predicted wear amount.
