Abstract: A cable as may be used in a tire, including a pneumatic tire. The cable is constructed in a manner that can provide a desired stiffness to a tire as well as a certain amount of structural elongation. The cable can be provided in a manner that does not necessarily result in an increase in the overall weight of the tire as would occur by e.g., increasing the diameter of a conventional cable construction.

Abstract: A pneumatic tire for a passenger car includes a belt layer and a belt cover layer formed by winding a steel cord member in the tire circumference direction on the outer peripheral side of the belt layer. The steel cord member has a structure in which element wires made of steel and having a diameter smaller than 0.18 mm are twisted together to form each strand and the strands are twisted together in the same direction as the direction of twisting of the element wires. The twist pitch on each of the strands is smaller than the twist pitch on the steel cord member, the twist pitch on the strand is 1.0 mm to 2.1 mm, and the twist pitch on the steel cord member is 2.0 mm to 5.25 mm.

Abstract: A cable (211) is provided comprising a steel cord (212) and a polymer material (215). The steel filaments (213) of the steel cord (212) are coated with an adhesive before the penetration of the polymer material (215). The cable (211) has a structural elongation less than 0.025% and an E module 4% greater than the E module of the steel cord (212). These two improvements further decrease the total elongation of the cable at certain load.
