A pneumatic tire includes: a belt layer in which a belt cord is arranged; and a belt reinforcing layer in which an organic fiber cord is arranged, the belt reinforcing layer is formed by coating the organic fiber cord with rubber, and a ratio (Sr/Sc) of a rubber cross-sectional area (Sr) to a cord cross-sectional area (Sc) is 1.0 to 1.5, and a value obtained by dividing, by 1000, a sum of a product (A) of a load LASE5% (N) at 5% elongation of the organic fiber cord, a cord count (per 25 mm), and the number of belt reinforcing layers, and a product (B) of a load (N) at 0.5% elongation of the belt cord, cos θ in which a belt angle is defined as θ, a cord count (per inch), and the number of belt layers is 8.7 or more.

The tire comprises a crown reinforcing zone comprising a ply of strips, each forming an angle of less than or equal to 10° with the circumferential direction. Each reinforcing strip is formed by a laminate made up of n inner composite layers comprising low-modulus oriented fibres parallel to each other, the angle of which with the circumferential direction is, in absolute terms, less than or equal to 10°, together with m outer composite layers on either side of the inner composite layers, comprising high-modulus oriented fibres parallel to each other, the angle of which with the circumferential direction is, in absolute terms, strictly greater than 10°. The high- and low-modulus fibres are coated with a polymer matrix.

Motorcycles tyre including a carcass structure, a zero-degree belt structure arranged in a radially outer position with respect to the carcass structure and a tread band arranged in a radially outer position with respect to the belt structure. The belt structure includes at least one hybrid reinforcing cord that has an elongation greater than 4% when subjected to a load equal to about 50 N and a tangent modulus with a monotonic progression as the elongation increases for elongations comprised between 4% and at least 9%.

The invention relates to a tyre (10) comprising a hooping ply (19) comprising at least one textile wire-like hoop reinforcer element making an angle strictly less than 10° with the circumferential direction (Z) of the tyre (10). The bonded textile wire-like reinforcer element has, before the step of production of the hooping ply (19), a tangent modulus less than or equal to 5 cN/tex/% for any elongation less than or equal to 3%. The textile wire-like hoop reinforcer element has, once extracted from the tyre (10), a tangent modulus greater than or equal to 5 cN/tex/% for any elongation greater than or equal to 4%.

The invention relates to a tyre comprising a working reinforcement comprising a single working ply, a carcass reinforcement and a hoop reinforcement. The hooping reinforcing textile filamentary element or elements (480), the working reinforcing filamentary elements (460) and the carcass reinforcing filamentary elements (440) are arranged so as to form a triangular mesh in projection on the circumferential equatorial plane (E). The or each hooping reinforcing textile filamentary element (480) is formed by a cord (30) with a triple twist (T1, T2, T3), comprising an assembly (25) consisting of N>1 strands (20a, 20b, 20c) twisted together with a twist T3 in a direction D2, each strand consisting of M>1 pre-strands, which are themselves twisted together with a twist T2 (T2a, T2b, T2c) in a direction D1 opposite to D2, each pre-strand itself consisting in a yarn that has been previously twisted about itself with a twist T1 in the direction D1, wherein at least half of the N times M yarns consist of elementary monofilaments of aromatic polyamide or aromatic copolyamide.

A tire includes a carcass ply, two beads, two sidewalls, and a crown reinforcing zone. The carcass ply connects the two beads by way of the two sidewalls. The crown reinforcing zone is positioned radially external to the carcass ply. The crown reinforcing zone includes a plurality of reinforcing strips disposed in at least two layers. The reinforcing strips are coated in an elastomeric composition. A mean overlap between the reinforcing strips of the two layers is greater than 40%. The reinforcing strips are made of a thermoplastic film having a modulus greater than 0.9 GPa, and preferably greater than 2 GPa, in a main direction and in a transverse direction.

The invention relates to a reinforcement layer for elastomeric products, in particular for the belt bandage (8), having cords as reinforcement, where the cords have at least two yarns, where a first yarn of the yarns is made of polyamide and where the ends of all yarns of a cord are twisted together. The problem addressed by the invention is that of providing a reinforcement layer for elastomeric products which exhibits a relatively high tensile force value for an elongation of 4% or more and which exhibits relatively low shrinkage based on linear density of the reinforcement. This is achieved in that the cords are hybrid cords having precisely three yarns, in that the hybrid cord has the first yarn and a second yarn made of HMLS-PET, in that the hybrid cord has a first yarn or a second yarn as third yarn, and in that the linear density of each hybrid cord is at least 5000 dtex.

A tire (10) comprises a crown (12) comprising a tread (20), a crown reinforcement (14), a carcass reinforcement (32), two side walls (22), two beads (24), each side wall (22) linking each bead (24) to the crown (12), the crown reinforcement (14) extending in the crown (12) in a circumferential direction (Z) of the tire (10). The textile wire-like hoop reinforcer element (48), the wire-like working reinforcer elements (46) and the wire-like carcass reinforcer elements (44) are arranged so as to define, in projection on the equatorial circumferential plane (E), a triangular mesh. The textile wire-like hoop reinforcer element comprises a core composed of a first strand comprising at least one monofilament, and a layer comprising at least two second strands, each second strand comprising at least one monofilament, each second strand of the layer being helically wound around the core.

A pneumatic tire comprising a carcass 12, at least one inclined belt layer 13, at least one first circumferential cord layer 14 arranged inward in the tire radial direction of the inclined belt layer 13, a tread 16 arranged outward in the tire radial direction of the inclined belt layer 13, and a second circumferential cord layer 15 which is arranged outward in the tire radial direction so as to cover a tire width direction end of the inclined belt layer 13, and where X is defined as X=Y=nmd, Y is the Young's modulus (GPa) of the cord, n is the number of cords implanted (cords/50 mm), d is the cord diameter (mm), and m is the number of the first circumferential cord layers 14, X is smaller than X of the first circumferential cord layer 14.

A radial tire (1) for a heavy-duty vehicle, in which the reinforcing elements of each hooping layer (331, 332, 333), forming an angle at most equal to 5? with the circumferential direction, and the reinforcing elements of the transverse reinforcer layers (321, 322, 323), forming an angle of between 10? and 45? with the circumferential direction, are extensible and therefore such that, in their rubberized state extracted from a polymer matrix, their structural elongation As is at least equal to 0.5%, their total elongation at break At is at least equal to 3% and their tensile Young's modulus E is at most equal to 150 GPa.
