Abstract:
A rubber composition obtained by kneading a mixture comprising 100 parts by weight of a component (A), 5-100 parts by weight of a component (B), 1-15 parts by weight of a component (C) and 1-20 parts by weight of a component (D), while maintaining the temperature during kneading at 200.degree. C. or less, wherein(A) is a solution polymerized diene rubber,(B) is silica,(C) is a silane coupling agent, and(D) is a low molecular weight organic silicon compound having at least one hydroxyl group represented by the following formula (3): ##STR4## wherein A and B independently represent a hydroxyl group; l and m independently represent integers of 2-10; j and k independently represent integers of 0-20; and X.sub.1 -X.sub.6 independently represent a phenyl group, a vinyl group or a group represented by the following formula (4):--C.sub.n H.sub.2n Y (4)wherein Y represents a hydrogen atom or a hydroxyl group and n represents an integer of 0-20, said organic silicon compound having a number average molecular weight of about 100-10,000.
