<p>A tire cord for the belts of radial or bias-belted tires consists of only two brass-coated high tensile steel wires which are helically twisted to have a lay length of from l4 to l8 millimeters. Each of the wires preferably has a diameter of 0.28 millimeters and is composed of steel which has a carbon content of at least 0.80% by weight. The cord is flexible and light, but strong. The void present at the centre of a three-wire cord is avoided. </p> |
