Metal cords and pneumatic tires using the same

A metal cord is constructed by twisting three metal filaments in the same direction, and satisfies Lmax>/=1.05d, Lmin>/=1d and Lmax/Lmin>/=1.05 (Lmax : center distance between longest separated metal filaments, Lmin : center distance between shortest separated metal filaments, d : diameter...

Beschreibung
Zusammenfassung:	A metal cord is constructed by twisting three metal filaments in the same direction, and satisfies Lmax>/=1.05d, Lmin>/=1d and Lmax/Lmin>/=1.05 (Lmax : center distance between longest separated metal filaments, Lmin : center distance between shortest separated metal filaments, d : diameter of metal filament), and has specified twisting pitch and elongation under a load of 5 kg/cord. A pneumatic tire comprises a belt composed of plural belt layers each containing the above metal cords arranged at a given inclination angle with respect to the circumferential direction of the tire.
