Abstract: A pneumatic tire which offers extremely excellent durability through inclusion of a belt portion composed of a rubber composition having excellent reinforcing properties, high hardness, low heat build-up properties, excellent deterioration resistance, and excellent adhesiveness to steel cords, wherein the rubber composition contains a natural rubber prepared by graft polymerizing a natural rubber latex with a polar group-containing monomer, and solidifying and drying the resulting product. A pneumatic tire which offers excellent rolling resistance through inclusion of a ply coating rubber, squeegee rubber, or tie rubber composed of a rubber composition containing a modified natural rubber prepared by graft polymerizing a natural rubber latex with a polar group-containing monomer, and solidifying and drying the resulting product.
