摘要

A light weight cable bead core (30) is described having an inner core (33) made of a metal wire (34) with an outer sheath (35) of steel cord wires (36). Each cord (36) is made of a plurality of filaments (37). The bead core (30) is particularly suited for heavy-duty service conditions in tires (100) for aircraft, off-road equipment, and commercial trucks.
