Provided is a pneumatic tire with an annular-shaped tread portion extending in a tire circumferential direction, a pair of sidewall portions disposed on both sides of the tread portion, and a pair of bead portions disposed inward of these sidewall portions in a tire radial direction. This pneumatic tire is also provided with a reinforcing member which includes a plurality of reinforcing cords oriented in at least three directions, and has a mesh-like structure with at least three of the reinforcing cords oriented in different directions joined together at at least a portion of intersecting locations of the reinforcing cords.

A radial tire includes a pair of bead cores, a carcass layer having one or more carcass plies extending from one of the bead cores to another of the bead cores in a toroidal form, a tread portion circumferentially encircling the toroidal form of the carcass layer, and a belt layer having a main belt layer, a first, unreinforced cushion layer disposed on a radially outer side of the main belt layer, a protective belt layer disposed on a radially outer side of the first cushion layer, and a second, unreinforced cushion layer disposed on a radially outer side of the protective belt layer and a radially inner side of the tread portion. The first, unreinforced cushion layer has a radial thickness between 2.0 mm and 10.0 mm.

The invention relates to a rubberized reinforcing ply (1) for articles consisting of an elastomeric material, preferably for vehicle tires, wherein the reinforcing ply (1) has a multiplicity of textile strengthening members (2) which are arranged parallel to and spaced apart from one another, wherein each textile strengthening member (2) is composed of at least one twisted multifilament yarn composed of the material viscose. The reinforcing ply (1) satisfies the following condition: (D.sup.2/E.sub.0) in mm corresponds to a value in a range from 0.30 mm to 0.45 mm, and the reinforcing ply (1) has a strength of 11 kN/dm<x<20 kN/dm, where D is the diameter of the textile strengthening member (2) in mm and lies in a range from 0.38 mm to 0.48 mm, and where E.sub.0=100/epdm.

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 greater than or equal to 55 GPa, which are parallel to one another and coated in a polymer matrix.

A radial tire comprises a multilayer composite laminate (10) comprising at least three superposed layers of reinforcers (110, 120, 130), the reinforcers being unidirectional within each layer and embedded in a thickness of rubber (C1, C2, C3, respectively), with a first layer of rubber (C1) comprising at least one row of heat-shrinkable circumferential textile reinforcers (110), for example made of nylon or polyester. The first layer radially (in the direction Z) surmounts two other layers (C2, C3) comprising metal reinforcers (120, 130) which are crossed from one layer to the next, in the form of steel monofilaments of a diameter between 0.20 mm and 0.50 mm. The reinforcers (110) made of heat-shrinkable textile material are tapes of thickness denoted T between 0.1 mm and 1 mm, and of thickness denoted W between 2 and 50 mm.

A band 12 includes a center portion C, a pair of intermediate portions M, and a pair of outer end portions E. The center portion C is formed from a first band member 40 and that extends in a circumferential direction. Each intermediate portion M is formed from a second band member 42 and that extends so as to form a mesh-like shape. The second band member 42 includes a plurality of first tilt portions 44 extending so as to be tilted relative to the circumferential direction and a plurality of second tilt portions 46 extending so as to be tilted relative to the circumferential direction in a direction opposite to a direction in which the first tilt portions 44 are tilted. Each outer end portion E is formed from a third band member 54 and that extends in the circumferential direction.

A functionalized polyamide is prepared by reacting a thio acid with an amide monomer or a mixture of a diamine and a dicarboxylic acid. In the reaction, the amide monomer is preferably a lactam compound, the thio acid has a formula of HOOC-A-SH wherein A represents an alkylene group containing from 1 to 10 carbon atoms, the diamine is an aliphatic diamine and the dicarboxylic acid is a aliphatic dicarboxylic acid. The functionalized polyamide can be vulcanized directly with rubber, which results in the use of less dip for adhering the tire cord to the rubber.

A pneumatic vehicle tire has at least a tread with an outer tread cap with a profiled tread surface, an inner tread base and at least one electrically conductive conductivity strip. The conductivity strip extends in a radial direction from the tread base, through the tread cap, to the tread surface. The tire further includes an electrically non-conductive belt bandage arranged under the tread base and the belt bandage has a multiplicity of gaps, a multi-ply belt, a carcass and side walls. The gaps in the belt bandage are filled with an electrically conductive material.

A fiber belt including at least one ferrous element is provided. The inclusion of the ferrous element, for example a ferrous cord, may permit magnetic manipulation of the belt. In one embodiment, a tire belt is provided, the belt comprising: a plurality of non-magnetic cords oriented in a row substantially parallel to one another; at least one ferrous cord oriented in a row substantially parallel to the plurality of non-magnetic cords; and wherein the plurality of non-magnetic cords and the at least one ferrous cord are calendered in a rubber material.
