<p>Provided is technology for reducing tire weight while suppressing the occurrence of defective products resulting from deformation by improving a cord structure for steel cords used in carcass plies and thus improving resistance to deformation in tires arising during storage in a non-vulcanized state. This steel cord for reinforcing a rubber article has a double twisted structure formed by a plurality of strands (11, 12), each of which is formed by intertwining a plurality of wires (1, 2, 3) in a twisted layer structure, intertwined in a two-layer twisted layer structure. The cord mass is 35 - 65 g/m, and the ratio G/A (N) of flexural rigidity (G) (N∙mm</p> |
