摘要：
Steel reinforcing cords (36) having four or more filaments (38, 40, 42 and 44) in two groups, one twisted and the other untwisted with a filament tensile strength TS equal to K.sub.1 -K.sub.2 D where K.sub.1 =4080N/mm.sup.2, and D is a filament diameter in mm to form cords with a break load equal to N(720.40D.sup.2 -352.6D.sup.3 ; CE is the cord efficiency, D is the filament diameter in millimeters and N is the number of filaments.
