PROBLEM TO BE SOLVED: To provide a method for producing a retreaded tire for an aircraft which can produce a retreaded tire for an aircraft capable of securely suppressing production defects and appearance defects, and to provide a mold for regeneration used when a retreaded tire for an aircraft is produced. SOLUTION: Disclosed is a method for producing a retreated tire for an aircraft which produces a retreaded tire 1D in which an internal pressure average growth rate (Gp) from an internal pressure 0 kPa to a prescribed internal pressure is 1 to 4%, on the condition designing a retreaded tire 1D in such a manner that its cross-sectional shape and dimensions are made the same as those of a new tire 1A, provided that the inside diameter of the mold 10 for regeneration is defined as D<SB>M</SB>, the average value of the external diameter under the inner pressure 0 kPa in the new tire 1A is defined as D<SB>A</SB>, and the inside diameter of a mold for molding a new tire is defined as D<SB>N</SB>, the relation of äD<SB>A</SB>+(Gp/1000)×(D<SB>A</SB>+4)}×1.004≤D<SB>M</SB>≤D<SB>N</SB>is satisfied, and the mold 10 for regeneration is used in a vulcanizing process.
