A flat or planar reinforcer shaped as a multicomposite strip (R1), which is defined by three main perpendicular directions: an axial direction (X), a transverse direction (Y), and a radial direction (Z), has a width L.sub.R in the Y direction of between 2 and 100 mm, and has a thickness E.sub.R in the Z direction of between 0.1 and 5 mm. A ratio L.sub.R/E.sub.R is greater than 3. The multicomposite strip includes a plurality of monofilaments made of a composite material. The monofilaments are oriented along the X direction and include filaments of a mineral material embedded in a thermoset resin having a glass transition temperature Tg.sub.1 that is greater than 70 C. The monofilaments are coated in a layer of thermoplastic material. The reinforcer may be used to reinforce a tire and a multilayer laminate, which may be used to reinforce a tire.

The present technology provides a pneumatic tire having a strip-shaped sound-absorbing member bonded on the inner surface of the tire includes a plurality of belt layers, two or more belt cover layers, one or more belt edge cover layers, and a thread rubber layer. The thickness of the tread rubber layer is substantially uniform in the region X where the sound-absorbing member is located so that the difference between the thickness t1 at an end of the sound-absorbing member and the thickness t0 at the position of the tire equator is equal to or less than 0.5 mm. The thickness of the tread rubber layer is smaller in the region Y where the belt edge cover layer is located than in the region X so that the difference between the minimum value t2 of the thickness in the region Y and the thickness t0 ranges from 1.0 to 4.0 mm.

A pneumatic tire comprises a carcass layer, a belt layer radially outward of the carcass layer, and a tread rubber radially outward of the belt layer. A belt cord angle of a belt layer large angle belt is 45-70, opposite sign belt cord angles of cross belts are 10-45, and a reinforcing layer belt cord angle is within 5 of a circumferential direction. A reinforcing layer width Ws and a carcass cross-sectional width Wca satisfy 0.60Ws/Wca0.70. The reinforcing layer is radially outward of the cross belts which are radially outward of the large angle belt. A wider cross belt width Wb2 of the pair and Wca satisfy 0.79Wb2/Wca0.89. Wb2 and Wca satisfy 0.79Wb2/Wca0.89. Relationships 0.79Wb2/Wca0.84 and either 0.82TW/Wca0.92 or 0.79TW/SW0.89 are satisfied, where TW is a tread width and SW is a total tire width.

A pneumatic tire comprises a carcass layer, a belt layer radially outward of the carcass layer, and a tread rubber radially outward of the belt layer. The belt layer is formed by laminating a large angle belt having a belt-cord angle of 45-70, a pair of cross belts having belt cord angles of 10-45 with opposite sign belt cord angles, and a reinforcing layer having a belt cord angle satisfying 5 relative to a circumferential direction. A reinforcing layer width Ws and a carcass cross-sectional width Wca satisfy 0.60Ws/Wca0.70. A wider cross belt width Wb2 of the pair of cross belts and the carcass width Wca satisfy 0.79Wb2/Wca0.89. Relationships 0.79Wb2/Wca0.84 and either 0.82TW/Wca0.92 or 0.79TW/SW0.89 are satisfied, where TW is a tread width and SW is a total tire width.

The invention relates to a pneumatic vehicle tire of radial construction having a tread (1), a radial carcass, a belt bandage (8) having at least two belt plies (8a, 8b) and having at least one belt bandage ply (9), which is arranged radially outside the belt, wherein the belt bandage ply comprises cords of at least two multifilament yarns twisted together which are arranged parallel to one another inside the belt bandage ply (9) and wherein the multifilament yarns are made of recycled polyethylene terephthalate (rPET). At a force of 1.56 cN/dtex the rPET cord (10) has an elongation of 2% to 5% at 20 C. and an elongation of 6% to 9% at 120 C., the sum of the breaking elongation of the rPET cord (10) and the heat shrinkage determined at 180 C. at a preload force of 0.01 cN/dtex and a time of exposure of two minutes is greater than 17%, and the rPET cord (10) has a heat shrinkage determined at 180 C. at a preload force of 0.01 cN/dtex and a time of exposure of two minutes of greater than 2.5%.

A pneumatic vehicle tire for passenger cars comprises a carcass, a tread, and a belt which has belt plies and which is covered radially outwardly by a belt bandage having strengthening elements oriented approximately in the circumferential direction, the belt bandage comprising at least one belt bandage ply each consisting of a central section and two lateral sections each arranged next to the central section without overlapping the central section, the strengthening elements of the central section being x1 construction and the strengthening elements of each lateral section being identical cords of x2 or higher construction, the density of the strengthening elements in the central section being less than the density of the strengthening elements in the lateral sections, and the axial distance of each lateral section inner end from the closest end of the widest belt ply being 5-30 mm.

A tire including a belt having a steel cord belt layer, and a bandage externally bearing radially on the belt. The bandage includes a rubber strip containing reinforcement cord. This rubber strip is wound about the belt at least from one axial belt end up to at least the other axial belt end, the ratio of the axial winding component to the circumferential winding component along the rubber strip is less than 0.01, and, over at least 70% of the axial belt width, does not vary by more than 2%. The spacing of two neighboring cords in two adjacent portions of the wound rubber strip at each circumferential position does not vary by more than 5% compared to the spacing of the cords in the rubber strip. The cords in the bandage are subjected to tension of at least 3 N/mm.sup.2 over at least 25% of the axial belt width.
