    Abstract: A steel cord (10) adapted for the reinforcement of elastomers comprises: a core steel filament (12) with a core steel filament diameter d c and coated with a polymer (14); six intermediate steel filaments (16) with an intermediate steel filament diameter d i smaller than or equal to the core steel filament diameter d c ; these intermediate steel filaments (16) are twisted around the core steel filament (12); ten or eleven outer steel filaments (18) with an outer steel filament diameter d o smaller than or equal to the intermediate steel filament diameter d I ; these outer steel filaments (18) are twisted around the intermediate steel filaments (16), the outer steel filaments (18) are preformed in order to allow rubber penetration inside the core (10). The core steel filament (12), the intermediate steel filaments (16) and the outer steel filaments (18) all have a tensile strength at least 2600 MPa. The cord (10) has an outer diameter D according to following formula: D ≤ d c + 2xd i + 2xd o + 0.1 wherein all diameters are expressed in millimeter (mm).

    Abstract: The present invention provides structure of steel cord in heavy duty tires, in which the adhesive strength between filament and rubber, and penetrating property of rubber are improved by making the twist direction of core and strand different in the steel cord comprising core and strand filament, and by making the pitch or the twist period of core and strand different. In particular, this structure is applied to steel cord of 3+8*d(HT) which is used in heavy duty tires. In this application, twist direction of core filament is in the S direction and twist direction of strand filament is in the Z direction, and the ratio of the pitch of core filament (CP) and the pitch of strand filament (SP) is between 0.50 and 0.94.
