<p>PROBLEM TO BE SOLVED: To provide a compound which improves low heat build-up performance of a rubber composition.SOLUTION: A rubber composition contains 0.1-10 pts.mass of at least one selected from the group consisting of thiohydrazide compounds represented by formula (1) or formula (2) and 30-150 pts.mass of a filler based on 100 pts.mass of a rubber component containing a diene rubber. (In the formulae, R, R, and Reach represent a hydrogen atom or an optionally substituted C1-C15 hydrocarbon group, and X represents a hydrogen atom, an amino group, a hydroxyl group, a C1-C15 hydrocarbon group, or a group represented by formula (3) or formula (4).)</p> |
