Abstract
In a tire the strength of steel cord and the resilience of rubber are a successful combination. However, in some specific areas of a tire, more elongation is expected from the steel cord, while still a sufficient degree of stiffness is expected. A steel cord is presented that has these properties. The steel cord comprises two or more steel elements that are twisted together. The steel elements comprise one or more steel filaments. In total the steel cord comprises ‘N’ filaments, each with a cross sectional area ‘A’. When the steel elements are individualised out of the steel cord they show a helix pitch length of ‘Lo’, while a single pitch has a centre line length of ‘S’. The inventive steel cord shows a ‘P’ value of at least 50 newton, wherein P=πNE (A/S)2. Further methods are presented to produce this steel cord.
