PROBLEM TO BE SOLVED: To provide a tire member such as a tread rubber, a side wall, a chafer and a bead filler, which has reduced heat generating property.SOLUTION: There is provided a tire member which comprises a rubber composition comprising a specific 4-aminophenyl-carboxylic acid amide compound, a hydrazide compound and a carbon black, wherein examples of a rubber component include a natural rubber, an isoprene rubber, a butadiene rubber, a styrene-butadiene rubber, a nitrile rubber and a chloroprene rubber.EFFECT: Since a specific 4-aminophenyl-carboxylic acid amide compound and a hydrazide compound are used in combination, the heat generating property can be reduced, compared with the single use of the hydrazide compound. It is considered that both compounds are reacted with an active functional group on the surface of carbon black at different sites to improve the dispersibility of carbon black and reduce the heat generating property.SELECTED DRAWING: None
