A composite cord is composed of two first strands formed of aramid fibers and one second strand formed of nylon fibers. In a cross section perpendicular to a length direction, a ratio L2/L0 of a length L2 of an exposed surface of the second strand along the outer cord periphery to a length L0 of an exposed surface of the composite cord along the outer cord periphery is in a range of 0.30 or more and 0.40 or less.

According to the present disclosure, there is disclosed a hybrid tire cord capable of realizing high performance and weight reduction of a tire by having strong adhesion to rubber and excellent fatigue resistance as well as high tenacity and high modulus by providing a cabled yarn in which an aramid hybrid Z-twisted yarn composed of an aramid multifilament yarn and an aramid spun yarn; and a general-purpose Z-twisted yarn are S-twisted together. There is also provided a method for manufacturing the same.

In a pneumatic tire according to an embodiment, a belt layer is configured such that the angle of a belt cord relative to the tire circumferential direction is more than 30° and 40° or less. An organic fiber cord of a belt-reinforcing layer, which is placed on the radially outer side of the belt layer, is configured such that when the number of twists per 10 cm length is T (twists/10 cm), the fineness is D (dtex), and the fiber density is ρ (g/cm.sup.3), the twist coefficient K defined as T×(D/ρ).sup.1/2 is 900 to 2,600, and the product of the load at 5% elongation LASE 5% (N) of the organic fiber cord and the end count E (cords/25 mm) of the organic fiber cord is 1,000 N or more.

A metal or metallized reinforcer, at least the surface of which is at least partially metallic, comprises at least a metallic part coated with a polybenzoxazine, the repeat units of which comprise at least one unit corresponding to the formulae (I) or (II): ##STR00001##
in which Z.sub.1 and Z.sub.2, which are identical or different, represent an at least divalent, aliphatic, cycloaliphatic or aromatic bonding group comprising at least one carbon atom and optionally at least one heteroatom selected from O, S, N and P. Such a reinforcement can be used for the reinforcement of a rubber article, in particular a motor vehicle tire.
