Claim:
1. A rubber composition comprising: a diene polymer comprising natural rubber and polybutadiene rubber, wherein a proportion of content of the natural rubber to total content of the natural rubber and the polybutadiene rubber is 15% to 65% by mass; 0.2 parts to 3 parts by mass of a citraconimide compound per 100 parts by mass of the diene polymer; 0.2 parts to 3 parts by mass of a hydrazone compound per 100 parts by mass of the diene polymer; and 0.8 parts to 2.1 parts by mass of a vulcanization accelerator comprising di-2-benzothiazyl-disulfide and N-tert-butyl-2-benzothiazolylsulfenamide per 100 parts by mass of the diene polymer, wherein content of the di-2-benzothiazyl-disulfide is 0.2 parts to 1.5 parts by mass per 100 parts by mass of the diene polymer.
