Zusammenfassung:	To provide: a rubber composition excellent in fracture characteristics while maintaining hardness; and a pneumatic tire using the same.SOLUTION: The rubber composition contains, based on 100 pts.mass of a diene-based rubber, 0.1 to 10 pts.mass of a thioester-based compound represented by the general formula (1) defined by A-COS-(CH2)n-SCO-A (A are each an alkyl group or aromatic hydrocarbon group having 1 to 10 carbon atoms, and may be the same as or different from each other, and n is an integer from 1 to 6).SELECTED DRAWING: None 【課題】硬度を維持しつつ、破壊特性に優れたゴム組成物、及びそれを用いた空気入りタイヤを提供することを目的とする。【解決手段】ジエン系ゴム１００質量部に対して、一般式（１）で表されるチオエステル系化合物（Ａは炭素数１～１０のアルキル基又は芳香族炭化水素基であり、それぞれ同じでも異なっていてもよく、ｎは１～６の整数）を０．１～１０質量部含有するものとする。Ａ－ＣＯＳ－（ＣＨ２）ｎ－ＳＣＯ－Ａ・・・（１）【選択図】なし
