PROBLEM TO BE SOLVED: To enable the manufacture of an aircraft regenerated tire excellent in durability which can reduce the calorific value of a shoulder part during travel and the shear force in a circumferential direction of a tire.SOLUTION: In a manufacturing method for an aircraft regenerated tire, aircraft regenerated tire is manufacture by use of a regenerated tire vulcanization molding die 1A where a diameter dimension 1X of a regenerated tire vulcanization molding die at a position by 60% - 75% of a distance A from a molding die width direction center position 3A of a tread formation face 2A, provided that the distance from the molding die width direction center position 3A to a molding die width direction outermost position 4F is the distance A, is formed into a smaller dimension than a diameter dimension 1Y of a new tire vulcanization molding die 1B at a position by 60% - 75% of a distance A from a molding die width direction center position 3B of a tire tread formation face 2B of a new tire vulcanization molding die 1B, provided that the distance from the molding die width direction center position 3B to the molding die width direction outermost position 4F is the distance A. |
