摘要： In a method of producing a pneumatic tire comprising a belt comprised of at least two belt layers each constituted with steel cords and a coating rubber covering the cord between a tread and a radial carcass by spirally winding a band-shaped uncured rubber composition extruded through an extruder on a rotating support to form a rubber member having a given sectional shape, a rubber composition formed by compounding a rubber component with a compound having a melting point of 120-220° C. and/or a resin having a softening point prior to curing of 90-150° C., in which a total compounding amount of the compound and the resin is 0.5-25 parts by mass based on 100 parts by mass of the rubber component, is applied in the coating rubber. In this method, the extrusion workability at the uncured state is good, and a tire having a high durability can be produced.
