To provide a sealant material composition that makes it possible to prevent the flow of a sealant caused by driving, while maintaining satisfactory sealability.SOLUTION: A sealant material composition forms a sealant layer 10 disposed on the inner surface of a pneumatic tire. The composition has a tensile stress at 20% elongation of 0.03 MPa or less at 23°C, and a tensile stress at 20% elongation of 0.002 MPa or more at 80°C.SELECTED DRAWING: Figure 1
