PROBLEM TO BE SOLVED: To provide a tire molding method capable of reducing remarkably the thickness of rubber at start and ending points of tire wrapping even using an extruder in a simple inner structure of a die in a tire molding method comprising wrapping rubber extruded continuously from an extruder around a rotating supporter. SOLUTION: A tire molding method includes molding a tire by wrapping a non-staining rubber B extruded continuously from the first extruder 1 around a molding drum 4, which includes at least a process of starting wrapping by bringing the first extruder 1 to a molding drum 4 and sticking the top end of an extruder non-staining rubber B to the molding drum 4, a process of increasing gradually an amount of the extruded non-staining rubber B while separating gradually the first extruder 1 from the molding drum 4 after starting of wrapping of the non-staining rubber B, and a process of decreasing gradually an amount of the extruded non-staining rubber B just before ending of wrapping of the non-staining rubber B.
