Abstract:
A rubber composition containing 100 parts by weight of a diene-based rubber, 20 to 120 parts by weight of silica, a sulfur-containing silane coupling agent of 3 to 15% by weight, based upon the weight of the silica and a tertiary amine compound having the formula (I): wherein, R1 indicates a carbon atom or nitrogen atom and, when R1 is a carbon atom, R2 indicates a hydrogen atom or hydroxyl group and having a pKa value of 6.5 to 13.
