To provide a rubber composition capable of improving a wear resistance, on-ice performance and driving stability on a dry road surface in a balanced manner, and to provide a winter tire using the composition.
The rubber composition includes a conjugated diene-based copolymer which has a structural unit based on a conjugated diene and a structural unit represented by formula (I) and in which at least one end of the polymer is modified by a silicone compound having a carbonyl group and/or ether group, and an isoprene-based rubber. In the formula, X1, X2 and X3 are each independently tertiary amino, hydroxy, hydrocarbyl or substituted hydrocarbyl, and at least one of X1, X2 and X3 is a carbonyl group, a group having an ether structure or a hydroxy group.
