ABSTRACT:
The present invention provides a rubber composition with superior properties with respect to processability, low fuel consumption, complex modulus, and durability, and tires prepared by using the rubber composition. The rubber composition of the present invention comprises: 2 to 2.9 parts by weight of (B) sulfur, 0.6 to 10 parts by weight of (C) at least one compound selected from the group consisting of a cresol resin, a resorcin condensate, and a modified resorcin condensate, and 10 to 55 parts by weight of (D) a carbon black and/or silica, based on 100 parts by weight of (A) a rubber component comprising a natural rubber and/or isoprene rubber and at least two kinds of synthetic rubbers selected from the group consisting of butadiene rubber, modified butadiene rubber, styrene-butadiene rubber, and modified styrene-butadiene rubber. The tire of the present invention is prepared by using the rubber composition.
