摘要： The present invention provides a rubber composition which provides a balanced improvement of initial wet grip performance, wet grip performance after aging, fuel economy, and abrasion resistance. Also provided is a pneumatic tire formed from the rubber composition. The rubber composition contains: a rubber component including a diene rubber; and a glycerol fatty acid triester of plant origin. The glycerol fatty acid triester has a content of saturated fatty acids of 10 to 25% by mass and a content of monovalent unsaturated fatty acids having one unsaturated bond of less than 50% by mass, each based on 100% by mass of the constituent fatty acids of the triester.
