ABSTRACT A rubber composition comprising the following components: (A) a rubber component comprising at least 50% by weight of a styrene/butadiene copolymer rubber; (B) an azodicarboxylic ester compound represented by the formula Image (I) wherein X is an alkyl of 3 to 8 carbon atoms, an unsubstituted or substituted phenyl, or an unsubstituted or substituted benzyl; (C) carbon black having a nitrogen absorption specific surface area of 100 to 250 m2/g and a dibutyl phthalate absorption number of 110 to 170 ml/100 g; (D) sulfur; and (E) a benzothiazole vulcanization accelerator. This rubber composition shows a high loss factor (tan .delta.) in a low temperature range, and besides shows a low loss factor in a high temperature range. Therefore, the composition when applied to the production of automobile tires, achieves improved braking power on a wet road surface and on a snow-covered or frozen road surface, as well as a lowered rolling resistance during driving. In addition, the strength characteristics of the composition are not lessened.
