A steel cord for rubber reinforcement that has a construction with an outer layer and an inner strand surrounded by and adjacent to the outer layer, the inner strand having at least one steel filament with a number of N1 and an average diameter of d1 expressed in mm, the outer layer having steel filaments with a number of N2 and an average diameter of d2 expressed in mm. The inner strand has a torque T1 and the outer layer has a torque T2, the relation between T1 and T2 is defined. By doing this, the tip rise problem of the rubber ply reinforced by steel cords is reduced.
