<p>PROBLEM TO BE SOLVED: To provide a rubber composition capable of improving low fuel consumption while maintaining processability, rubber strength, flexing crack growth resistance, and cord adhesion and a pneumatic tire produced using the rubber composition.SOLUTION: The rubber composition contains: a rubber component containing at least one kind of diene rubber selected from the group consisting of isoprene rubber, butadiene rubber, and styrene-butadiene rubber; carbon black having a nitrogen adsorption specific surface of 20 to 130 m/g; a compound represented by the formula (I); sulfur; at least one crosslinked resin selected from the group consisting of a cresol resin, a resorcinol resin, and a modified resorcinol resin; and at least one methylene donor selected from the group consisting of a partial condensation product of hexamethoxymethylolmelamine and a partial condensation product of hexamethylolmelamine pentamethyl ether. In the formula (I), Mrepresents a metal ion, and r represents the valence.</p> |
