PROBLEM TO BE SOLVED: To provide an additive for rubber capable of providing a rubber composition capable of achieving both low heat build-up properties and a high elastic modulus, a rubber composition containing the additive for rubber, and a pneumatic tire using the rubber composition.SOLUTION: The additive for rubber contains a benzimidazole compound represented by formula (I). The rubber composition contains the additive for rubber, and the pneumatic tire uses the rubber composition. [Q represents an amino group or a functional group represented by formula (Q) (Rand Rare each independently H, a 1-6C alkyl group, or a phenyl group which is unsubstituted or substituted with a halogen atom, a hydroxyl group, an amino group, a nitro group, a nitrile group, or a 1-6C alkyl group; and Rand Rmay be bonded to each other to form a 2-7C alkylene group).]SELECTED DRAWING: None
