Provided are: a rubber composition for tires having excellent handling stability; and a pneumatic tire using the same. A rubber composition for tires, which contains a rubber component, silica, and a compound represented by formula (I), and which has an acetone extraction amount of less than 16.0 mass%. (In formula (I), R1 represents a hydrocarbon group. R2 and R3 may be the same or different and each represents a hydrogen atom, a hydrocarbon group, or a-(AO) n-H group (n represents an integer of 1 or more, and each n of R2 and R3 may be the same or different. AO may be the same or different and each represents an oxyalkylene group having 2 or more carbon atoms. ), at least one of R2 and R3 is a-(AO) n-H group).

    提供一种操纵稳定性优异的轮胎用橡胶组合物以及使用其的充气轮胎。一种轮胎用橡胶组合物,含有橡胶成分、二氧化硅和下式(I)表示的化合物,丙酮提取量小于16.0质量%。(式(I)中,R1表示烃基。R2、R3相同或不同,表示氢原子、烃基或‑(AO)n‑H基(n表示1以上的整数,R2、R3的各n分别可相同或不同。AO相同或不同,表示碳数2以上的氧化烯基。),R2、R3中的至少一个为‑(AO)n‑H基)。
