The purpose of the present invention is to provide a rubber additive with which it is possible to provide a rubber composition having exceptional low heat build-up properties and workability, a rubber composition including the rubber additive, and a tire in which the rubber composition is used. To solve this problem, the present invention is characterized by containing a hydrazine compound represented by formula (I). (In the formula, R 1 and R 2 each independently represent a hydrogen atom, C1-16 alkyl group, or C2-6 alkenyl group, and A represents a group represented by formula (A-1) or formula (A-2).) |
