RUBBER COMPOSITION AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition that can improve rubber strength and low fuel consumption in well-balanced manner and a pneumatic tire using the rubber composition.SOLUTION: The rubber composition contains a rubber component, carbon black and a compound represented by the following formula (I), and the content of the carbon black is 10 to 100 parts by mass relative to 100 parts by mass of the rubber component. In the formula (I), Rand Rare the same or different and are a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 1 to 20 carbon atoms, or an alkynyl group having 1 to 20 carbon atoms, Mrepresents a metal ion, and r represents the valence thereof.
