The purpose of the present invention is to provide: a rubber composition that makes it possible to increase the modulus thereof while maintaining excellent low heat generation properties; and a pneumatic tire that uses the rubber composition. The present invention provides a rubber composition comprising a diene rubber, an acid-modified polyolefin (A), and a polyolefin (B). The ratio of the acid-modified polyolefin (A) to the polyolefin (B) is 1:5 to 5:1 by mass ratio. The total amount of the acid-modified polyolefin (A) and the polyolefin (B) is 3 to 60 parts by mass with respect to 100 parts by mass of the diene rubber. Also provided is a pneumatic tire that uses the rubber composition. |
