This pneumatic tire (1) includes: a pair of bead cores (11, 11); a carcass layer (13) extending between the pair of bead cores (11, 11); and a belt layer (14) including a laminate of at least four belt plies (141 to 144) having steel belt cords covered with coating rubber, the belt layer being disposed on the outer side in a tire radial direction of the carcass layer (13). An inter-cord distance (Ga) between an outermost layer belt ply (fourth belt (144)) and an adjacent belt ply (third belt (143)) has a relationship such that 0.80Ga/max1.80 with respect to a maximum value (max) of outer diameters (4, 3) of belt cords (1441, 1431) in the outermost layer belt ply (144) and the adjacent belt ply (143).

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.

A dipped and heat-set aramid cord, comprising a plurality of cord plies having a spacing between the plurality of cord plies, wherein a TASE at 2.0% elongation of the aramid cord is less than 2.0 cN/dtex; wherein the spacing between the plurality of cord plies is more than 10% and less than 80% of a cord diameter (D) of the cord plies.

Provided is a pneumatic tire where a total width (SW) and an outer diameter (OD) satisfy the relationship SW/OD0.3; an inner diameter (ID) and an outer diameter (OD) satisfy the relationship ID/OD0.7; as viewed in a tire meridional cross section, an area (X1) (mm.sup.2) of a first region (R1) and a periphery length (Y1) (mm) of an inner peripheral surface of the first region (R1) have a ratio X1/Y1 of 12 or greater and 30 or less; and an area X2 (mm.sup.2) of a second region (R2) and a periphery length (Y2) (mm) of an inner peripheral surface of the second region (R2) have a ratio X2/Y2 of 10 or greater and 15 or less.

The invention relates to a rubberized reinforcing ply for articles made of elastomeric material, preferably for vehicle tires, where the reinforcing ply has a multiplicity of parallel strengthening elements spaced apart from one another, with each strengthening element consisting of polyamide 6.6 and having an x1 construction, hence being a twisted multifilament yarn of polyamide 6.6. The crude yarn of polyamide 6.6 has a tenacity which, at an elongation of 4%, is within a range from 1.35 cN/dtex to 1.60 cN/dtex; the multifilament yarn has a tenacity which, at an elongation of 4%, is within a range from 2.0 cN/dtex to 2.8 cN/dtex, and the cord has a thermal shrinkage at 177 within a range of 4.0%-7.0%, wherein the tenacity in accordance with ASTM D885-16 and the thermal shrinkage at 77 C. are determined under a pre-tension of 0.045 g/dtex with an exposure time of two minutes.

The invention relates to a rubberized reinforcing ply for articles composed of elastomeric material, preferably for vehicle tires, wherein the reinforcing ply has a multiplicity of strengthening elements which are in parallel and spaced apart, wherein each strengthening element is a cord which is end-twisted from at least two twisted multifilament yarns composed of polyamide 6.6. The raw yarn composed of polyamide 6.6 has a tenacity which, at an elongation of 4%, is within a range from 1.35 cN/dtex to 1.60 cN/dtex, the cord has a tenacity which, at an elongation of 4%, is within a range from 1.2 cN/dtex to 2 cN/dtex and the cord has a thermal shrinkage at 177 within a range of 4.0%-7.0%, wherein the tenacity in accordance with ASTM D885-16 and the thermal shrinkage at 177 C. are determined under a pre-tension of 0.045 g/dtex with an exposure time of two minutes.

A pneumatic vehicle tire has a carcass, a belt and a profiled tread. The belt includes four belt plies wherein the third belt ply and the fourth belt ply are working plies. The reinforcement members of the working plies are arranged at an angle to the circumferential direction of 10 to 45 and the reinforcement members of the fourth belt ply at an angle of 10 to 45. The reinforcement members of the third and fourth belt plies are arranged such that they cross one another. The reinforcement members of the first belt ply are arranged at an angle of 40 to 75 and the reinforcement members of the second belt ply are arranged at an angle of 0 to 5 to the circumferential direction. The reinforcement members of the third belt ply and the reinforcement members of the first belt ply have the same direction of inclination.

Disclosed herein are vehicle tires including a tread, a carcass with at least one body ply, and a single steel cord-containing belt ply positioned radially inward of the tread and radially outward of the carcass. The single steel cord-containing belt ply comprises rubber reinforced with steel warp cords bi-axially woven with steel weft cords and have a specified bi-axial angle. Also disclosed is a vehicle tire containing the single steel cord-containing belt ply wherein the belt ply includes pick cords connecting the steel warp cords and steel weft cords.
