To provide a method for producing a sealant tire capable of achieving improvement in productivity.SOLUTION: There is provided a method for producing a sealant tire which comprises a step of preparing a sealant material and a step of applying the sealant material on the inner circumferential surface of a tire. The step of preparing the sealant material comprises a step SP1 of plasticizing a rubber component mainly composed of a butyl-based rubber in a kneading chamber of a batch-type kneader and a step SP2 of mixing a liquid rubber with the rubber component in the kneading chamber. The liquid rubber is divided into small portions, followed by feeding into the kneading chamber.SELECTED DRAWING: Figure 3
