    摘要: A rubber composition containing 100 parts by weight of a diene-based rubber and 0.5 to 25 parts by weight of a heat expandable microcapsule composed of a thermoplastic resin particle having a substance enclosed therein, capable of vaporizing or expanding due to heat to thereby generate a gas, wherein a shell of the heat expandable microcapsule comprises a thermoplastic resin obtained by polymerization from, as a main component of a monomer, a nitrile-based monomer (I), a monomer (II) having an unsaturated double bond and carboxyl group in the molecule thereof, a monomer (III) having two or more polymerizable double bonds and, optionally, a copolymerizable monomer (IV) for adjusting the expansion characteristics, and a pneumatic tire using the same, whereby the tire weight is decreased and the ice traction thereof is improved.
