    Abstract: PROBLEM TO BE SOLVED: To provide a rubber-steel cord composite suitable as a reinforcing material for a tire for high speed and heavy load, especially usable as the tire for an airplane, and to provide a pneumatic radial tire for the high speed and heavy load, having improved durability by applying the composite as a rubber-reinforcing material.
    SOLUTION: The steel cord has a multi-twisted structure obtained by twisting N (N=2 to 8) strands 2 each obtained by twisting a plurality of wires 1, satisfies the formula: ε
    C ≥0.005 [wherein, ε
    C is defined by the formula: ε
    C =√(-b/2+√(b
    2 /4-c))-1 (wherein b is -1+π
    2 (-4R
    2 +d
    2 )/P
    2 ; c is π
    2 d
    2 k(4π
    2 R
    2 +P
    2 )/P
    4 ; R is (D-d)/2; and k is tan
    2 (π/2-π/N))] when d (mm) is the diameter of the strand, D (mm) is the circumcircle diameter of the cord, and P (mm) is the twisting pitch of the cord, and has an elongation at break of ≥2.5%.
