Abstract
There is provided a rubber composition which can provide a tire having an excellent balance of the breaking properties, the rolling resistance performance (low fuel consumption) and the wet grip performance. The rubber composition includes 100 parts by mass of a diene rubber, and 1 to 100 parts by mass of fine particles (A) having a glass transition point of −70° C. to 0° C. and composed of a polymer comprising constituent units of at least one monofunctional monomer. The fine particles (A) have a crosslinked structure crosslinked by at least one polyfunctional monomer having a polysulfide bond in which at least two successive sulfur atoms are bonded together.
