ABSTRACT:
The present invention provides a rubber composition for a cap tread that can improve steering stability on a snowy road and a pneumatic tire having a cap tread using the rubber composition. The rubber composition for a cap tread comprises 5 to 200 parts by weight of a carbon black having an iodine adsorption amount of 100 to 300 mg/g, and 2 to 50 parts by weight of a silicone oil based on 100 parts by weight of at least one diene rubber selected from the group consisting of a natural rubber, an isoprene rubber, a styrene-butadiene rubber and a butadiene rubber, and 1 to 20 parts by weight of a silane coupling agent based on 100 parts by weight of the silicone oil, and the pneumatic tire having a cap tread is prepared by using the rubber composition.
