(EN) RUBBER COMPOSITION
(FR) COMPOSITION DE CAOUTCHOUC
(JA) タイヤ用ゴム組成物
Abstract
(EN)
The present invention provides a rubber composition having excellent workability, tensile strength at break, and fuel efficiency. The rubber composition for a tire according to the present invention comprises a diene rubber, silica, and a nonionic surfactant represented by formula (1) (in formula (1), b is 5-45 and a+c equals 55-95), wherein the contained amount of the silica is 50-200 parts by mass with respect to 100 parts by mass of the diene rubber, and the contained amount of the nonionic surfactant is 0.1-15 mass% with respect to the contained amount of the silica.
