Abstract
Provided is a technique for attaining tire weight reduction while inhibiting occurrence of a product defect caused by deformation by improving the structure of a steel cord used for a carcass ply to improve the resistivity against deformation of a green tire when stored in an unvulcanized state. Also provided is a steel cord for reinforcing rubber articles with a multi-twisted structure in which a plurality of strandsformed by twisting a plurality of wirestogether in a layered-twisted structure are twisted together in a 2-layer-twisted structure. The cord mass is from 35 g/m to 65 g/m, and the ratio of flexural rigidity G (N·mm) to cord cross section A (mm), G/A (N) is from 400 N to 650 N.
