ABSTRACT:
The present invention provides a rubber composition comprising natural rubber and/or diene synthetic rubbers, silica in an amount of 10 to 85 parts by weight per 100 parts by weight of the rubber, a specific silane coupling agent, i.e., a bis-(alkoxysilylalkyl) polysulfide having a polysulfide structure in which the distribution of sulfur is specified, in an amount of 1 to 20% by weight of the amount of silica, and provides a pneumatic tire manufactured by using the rubber composition. The pneumatic tire has excellent low heat buildup property, low rolling resistance, and reinforcing property.
