e/(0.31Wt+56.45)(formula 2).

A belt layer includes at least one belt ply. The belt ply includes a single-wire cord having a short diameter SD and a long diameter LD, with a ratio SD/LD between the short diameter SD and the long diameter LD being less than 1.00, and a topping rubber covering the single-wire cord. The single-wire cord is arranged so that a direction of the short diameter SD is oriented to a thickness direction of the belt ply. The topping rubber has a complex elastic modulus (E*) of less than 7 MPa under conditions of temperature of 70 degrees Celsius, initial strain of 10%, an amplitude of dynamic strain of ?1.0%, and a frequency of 10 Hz.

A radial tire with a lightened belt structure (10) comprises a multilayer composite laminate (10a, 10b, 10c) of specific construction, with a first layer (10a) of rubber (C1) reinforced with preferably weakly heat-shrinkable circumferential textile monofilaments (110) with a diameter greater than 0.10 mm or assemblies of such monofilaments, for example, made of nylon or of polyester, this first layer radially (in the direction Z) surmounting two other layers (10b, 10c) of rubber (C2, C3, respectively) reinforced with monofilaments (120, 130) of high tensile steel. The first reinforcers have an envelope diameter between 0.20 mm and 1.20 mm and a density, measured in the axial direction Y, between 70 and 130 threads/dm, and the second and third reinforcers each have a diameter between 0.20 mm and 0.50 mm and a density, measured in the axial direction Y, between 100 and 180 threads/dm.

The tire comprises a carcass ply connecting two beads via two sidewalls, the carcass ply being surmounted radially towards the outside of the tire by a crown reinforcing zone which is itself surmounted radially towards the outside of the tire by a tread, the crown reinforcing zone comprising a plurality of reinforcing strips arranged over at least one ply of strips. The strips are arranged so that they are juxtaposed and at an angle less than or equal to 15? with respect to the circumferential direction. Each reinforcing strip is made up of a laminate of at least 3 composite layers, each composite layer containing oriented fibers having a tensile modulus less than or equal to 30 GPa, which are parallel to one another and coated in a polymer matrix.

A reinforced product (21) comprises: an elastomer matrix (23), several reinforcing elements (44) embedded in the elastomer matrix (23), the reinforcing elements (44) being arranged side by side in a main direction (X1). Each reinforcing element (44) comprises: at least one filamentary element (46) comprising a single monofilament, and at least one sheath coating the filamentary elements (46) and comprising at least one layer of a thermoplastic polymer composition. The ratio R1=ODO/E of the mean minimum thickness ODO of elastomer present on the back of the sheath to the mean thickness E of the reinforced product (21) is less than or equal to 0.17, the mean minimum thickness of elastomer ODO and mean thickness E of the reinforced product (21) being measured in a direction (Y1) substantially perpendicular to the main direction (X1).

A composite wire has a thermoplastic core component and a sheath. The sheath includes at least two groups of reinforcement threads wrapped around the core component. The at least two groups of reinforcement threads form angles with the core component, with the overall sum of all angles which are essentially zero.

A tire is provided with a tire frame member that is made from resin and has a pair of bead portions, a pair of side portions that extend from the bead portions towards an outer side in a tire radial direction, and a crown portion that connects an outer side end in the tire radial direction of one side portion to an outer side end in the tire radial direction of another side portion, and with a crossing belt layer that is provided with plural reinforcing cords that are arranged in rows which are inclined relative to a tire rotation axis of the tire frame member and are coated with a resin material. The crossing belt layer is disposed either directly or via a resin layer on an outer side surface in the tire radial direction of the crown portion.

The cap ply reinforcement strip is a ready-to-use plain woven fabric and is composed of hybrid cord warps (3) and texturized weft yarns (2). The cap ply reinforcement strip for pneumatic tires (1) eliminates calendering and strip preparation steps by eliminating the need for rubber coating and decreases the rolling resistance of the tire and the fuel consumption.

Radial carcass tire for a civil engineering vehicle, having two bead wires (2) of radial height Ht, and carcass reinforcement made of two layers, the first (1) being radially innermost with a radial height Hdc, is anchored in each bead to form a main part (11) and a turn-up (12). The second layer (3) is radially outside the first layer (1). The free end (A) of the turn-up (12) is at a radial distance from the radially outermost point (21) of the bead wire that is at least equal to 1 and at most equal to 2 times Ht. From the end A of the turn-up (12) to the point B at 85% of the radial height Hdc, the distance between carcass layers is at least equal to 2 and at most equal to 11 times the diameter of metal reinforcers of first carcass layer (1).

A pneumatic vehicle tyre of radial type of construction, having a tread (1), having a carcass inlay (3), having electrically nonconductive sidewalls (7) and having at least one electrically conductive component (8) or element in a bead region, which component or element, in the case of a tyre mounted on a wheel rim, comes into contact with said wheel rim, wherein either the tread (1) is electrically conductive or, in the tread region, at least one electrically conductive component (10) is provided which is overlapped on the outside by the sidewalls (7) and which is connected in electrically conductive fashion to the tread outer surface, and wherein filaments provided with an electrically conductive coating are incorporated at least in a sidewall region, the coating of which filaments forms electrically conductive passages between the tread (1) or the component (10) and the at least one electrically conductive component (8) or element in the bead region.
