ABSTRACT:
The present invention provides a vulcanizable rubber composition comprising 100 parts by weight of a polymer component consisting of 30 to 80 wt. % of an ethylene.cndot..alpha.-olefin.cndot.non-conjugated diene copolymer having a Mooney viscosity of 10 to 100 (ML.sub.1+4 100.degree. C.) and an iodine value of 20 to 45 and containing ethylene and .alpha.-olefin in a weight ratio of 50:50 to 90:10, and 20 to 70 wt. % of a styrene-conjugated diolefin block copolymer, 20 to 150 parts by weight of a reinforcing filler, 3 to 30 parts by weight of sulfur, 0 to 50 parts by weight of a styrene resin and 0 to 100 parts by weight of an extending oil.
