Abstract

The present invention has its object to provide a rubber composition for a studless tire that contributes to both good braking force and high handling stability on ice or snow, and a high performance studless tire using the rubber composition. The rubber composition for the studless tire contains: a mixture of a zinc salt of an aliphatic carboxylic acid and a zinc salt of an aromatic carboxylic acid; an oil or a plasticizer; and a rubber component that comprises 40% by mass or more of a butadiene rubber relative to 100% by mass of a total amount of the rubber component.
