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 having a sealant layer on the inner circumferential surface, wherein the sealant layer is formed by using a sealant material containing a rubber component mainly composed of a butyl-based rubber, a large amount of a liquid rubber and a cross-linking agent. The production method comprises a step SP for preparing the sealant material, a step SK of storing the sealant material statically in a container and a step SA of applying the sealant material on the inner circumferential surface of the tire using an application machine. The sealant material in the container has a viscosity at 95°C of 15 kPa s or less.SELECTED DRAWING: Figure 2
