PROBLEM TO BE SOLVED: To provide a rubber composition for sealant material that can maintain low-temperature sealability satisfactorily, and a pneumatic tire (sealant tire) prepared therewith.SOLUTION: The present invention provides a rubber composition for sealant material. The rubber composition is stored at 25°C for 10 days during a period within 60 days after its production. Before and after its storage, the rubber composition is measured in viscosities at -20°C. A difference between these viscosities is 4.0 kPa s or less.SELECTED DRAWING: Figure 10
