PROBLEM TO BE SOLVED: To provide a rubber composition having excellent on-ice performance and a pneumatic tire using the rubber composition.SOLUTION: The rubber composition is obtained by mixing 100 pts.wt. of diene-based rubber with 0.3-20 pts.wt. of bowl-like fine particles composed of, for example, a methacrylic resin and having an average particle diameter of ≤100 μm. The pneumatic tire comprises tread composed of the rubber composition. Ground porous carbonized material of plant, e.g. plant-based granule such as ground walnut husk or ground bamboo charcoal and the porous cellulose particles may be used at the same time. |
