Claim:
A rubber composition comprising 100 parts by weight of a diene-based rubber, 10 to 160 parts by weight of, a reinforcing filler including silica and 0.1 to 2000 by weight, based upon the weight of the silica, of a mercaptosilane coupling agent represented by the following formula (III): wherein R 7 is a C 1 to C 8 linear or branched alkylene group, R 8 to R 10 are, independently, a C 1 to C 18 linear or branched alkyl group and/or a C 1 to C 18 alkyl group having an ether skeleton, blocked with a compound having a vinyl ether group represented by the formula (I): wherein A is an oxygen or sulfur atom, R 1 and R 3 are, independently, a hydrogen atom or a C 1 to C 18 alkyl group or a phenyl group and R 2 is a C 1 to C 18 alkyl group, a C 2 to C 18 alkenyl group or a C 2 to C 18 alkynyl group, or a phenyl group.
