Abstract

PURPOSE: To obtain a steel cord for tire belt reinforcement, having a special structure and characteristic, and providing improved durability to a tire while keeping good driving stability in turning at a high-speed, driving properties, braking properties, or the like. CONSTITUTION: This steel cord obtained by twisting 3-4 strands obtained by twisting 5-8 steel filaments around a core composed of 3 steel filaments together as a sheath to provide the strand, in the same direction as that of the sheath layer has the filament diameters regulated so that the diameter of at least one filament of the core may be 0.75-0.90 time as much as that of another filament constituting the cord, and any diameter of the filaments may be within the range of 0.05-0.10 mm, and has <=8.5 K-value defined by the equation [S is the strength (kg/cord) of the cord; E is the breaking elongation (%) of the cord; Y is the flexural modulus (kg.mm) of the cord].
