Abstract
A viscous rubber composition consisting mainly of a non-polar rubber, polybutene and white carbon has high adhesion and excellent puncture-sealing properties. Pneumatic tires provided with a puncture-sealing layer formed of such a viscous rubber composition have a high resistance against the puncture due to foreign substances penetrated through the tire.
