    Abstract: In the pneumatic tire of this invention, at least the outermost one of a plurality of rubber layers between the carcass and tread has been reinforced with a plurality of steel cords. Each of these steel cords is a single-strand steel cord with an elongation at break of not less than 4% and at least one of its component wires does not form a common circumcircle with the remaining wires. The curve circumscribing the cross-sections of the constituent wires of each steel cord is not a true circle. Furthermore, a high resistance to nail penetration is assured by arranging the steel cords in such a manner that, for a large majority of steel cords, the direction of maximum offset span of the circumscribing curve is substantially coincidental with the width direction of the outermost layer of rubber.

    Abstract: A pneumatic tire comprises a tread portion, a pair of sidewall portions, a pair of bead portions, and a carcass ply of steel cords extending between the bead portions through the tread portion and sidewall portions. Each of the carcass cords comprises a number nullnnull of steel filaments each having a diameter (d) of from 0.17 to 0.40 mm. The steel filaments are twisted together to have a null1nullnnull bundle-twist structure or an interlace-twist structure. In a vicinity of the maximum tire section width point P of each of the sidewall portions, a sectional shape coefficient S of each carcass cord is set in a range of from 0.5 to 0.9, wherein the sectional shape coefficient S is (d2nulln)/(L1nullL2), nullnnull is the number of the filaments, nulldnull is the average of the diameters of the filaments, nullL1null is the largest measure of distance between two extremities of the cord which occurs in a direction in a cross section of the cord, and nullL2null is the measure of distance between two extremities of the cord in a direction perpendicular to the above-mentioned direction.

    Abstract: A method for using a bunching type twisting machine to manufacture a steel cord made up of one core filament having a continuous wavy form and five to eight sheath filaments not having a wavy form disposed around the core filament, the cross-sectional shape of the cord forming an ellipse whose orientation is substantially constant in the length direction of the cord. After a core filament is preformed with a helical wavy form of a smaller pitch than the cord twisting pitch, this is squashed to form a flat helical core filament at a stage before it is twisted together with sheath filaments, and then sheath filaments are twisted around this flat helical core filament to make an intermediate product cord and this intermediate product cord is then squashed and thereby flattened before being taken up on a reel.
