Abstract
The present technology provides a rubber composition containing: (A) a diene rubber, (B) from 5 to 200 parts by mass of silica per 100 parts by mass of the diene rubber, (C) from 1 to 20 mass % of a sulfur-containing silane coupling agent relative to the amount of the silica, (D) for example, from 1 to 20 mass % of n-octyltriethoxysilane relative to the amount of the silica; and (E) from 1 to 20 mass % of a glycerol monofatty acid ester derived from a fatty acid having from 8 to 24 carbons relative to the mass of the silica (B).
