It is an object of the present invention to provide a steel cord for reinforcing rubber articles with improved durability against so-called cut properties such as cuts and perforations, and a tire for construction vehicles to which the steel cord for reinforcing rubber articles is applied as a reinforcing material.

- the core strand 1 has a four-layer twisted structure of 3 + 9 + 15 + 21.
- the ten sheath strands 2 twisted around the core strand 1 have a 3 + 9 + 15 three-layer twisted structure.
- the core strand and the sheath strand are preferably in the same direction twisted structure in order to make line contact in the strand and avoid breakage due to stress concentration.
- the present invention in order to ensure the strength of the rubber article, it is preferable to use a high tensile strength steel having a carbon content of 0.80 to 1.00% by mass for the wire used. Further, in order to suppress twisting of the cord and ensure factory workability, it is preferable to wrap the wrapping element wire 3 around the outer periphery of the cord.
- the strands constituting each strand preferably have a strand diameter in the range of 0.20 to 0.60 mm. If the diameter of each strand is less than 0.20 mm, sufficient tensile strength as a steel cord cannot be obtained. On the other hand, if it exceeds 0.60 mm, when the cord is applied to a tire, This is not preferable because the surface strain of the strands of the steel cord increases and the fatigue resistance decreases. In addition, in order to improve productivity, it is preferable that the strand used by a core strand and a sheath strand is respectively the same wire diameter.
- a construction vehicle tire shown in FIG. 7 can be preferably cited.
- a carcass 21 formed of a steel cord ply extending in a radial direction between a pair of bead cores 20 and a cord arranged side by side on the outer side in the tire radial direction of the crown portion of the carcass 21 are crossed between stacked layers.
