Abstract
A pneumatic tire sealing sheet according to the present invention includes a sealant layer. When G′1 represents a storage elastic modulus value at −20° C. of the sealant layer, T represents a probe tack value at 23° C. of the sealant layer, and A1 represents an adhesive strength value at 23° C. of the sealant layer to a tire, a ratio of a product of the probe tack value T and the adhesive strength value A1 to the storage elastic modulus value G′1 (A1×T/G′1) is 12.0 or less.
