    Abstract: A heavy duty pneumatic tire comprises a belt disposed radially outside a carcass and radially inside a tread portion, the belt comprising at least one ply of at least one high-elongation steel cord, the high-elongation steel cord being formed by twisting at least three waving steel filaments together to form a core and a sheath surrounding the core. The waving filaments change place repeatedly along the longitudinal direction of the cord such that one of the filaments forms the core in a portion, but in a different portion of the cord, the same filament forms part of the sheath, thereby defining a plurality of first parts with the core and a plurality of second parts without the core which are disposed alternately in the longitudinal direction of the cord. The elongation at break of the high-elongation steel cord is in the range of from 4 to 10%.

    Abstract: A wire cord for reinforcing rubber items, more particularly pneumatic tires for cars and trucks, comprises at least three wire filaments 2 arranged about a continuous core filament 3. The core filament 3 consists of a non-metallic material capable of longitudinal contraction when the rubber item 5 to be reinforced is vulcanized, this material being more particularly non-drawn nylon. On vulcanization of the rubber item 5 to be reinforced the core filament 3 contracts and expands in diameter.
