Abstract
Provided are a rubber composition for pneumatic tires which is excellent in adhesion, sealing performance, fluidity, and processability, and a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for pneumatic tires containing, per 100 parts by mass of a rubber component including a butyl-based rubber: 100 to 400 parts by mass of a liquid polymer; 1 to 40 parts by mass of an organic peroxide; and 1 to 40 parts by mass of a crosslinking activator.
