A tire comprises a tread portion provided with a band composed of at least one band cord wound spirally and circumferentially of the tire and embedded in the tread portion. When a band cord piece is taken out from the above-said at least one band cord embedded in the tread portion and measured for the length, a length Lb is equal to or smaller than a length La at least in a part of the tread portion, where the length Lb is measured at a first point of time after the band cord piece has been taken out, and the length La is measured at a second point of time after the first point of time.

A belt cover layer is formed by spirally winding belt cover materials including a first cover material and a second cover material. When one side in a tire width direction with respect to a tire equatorial plane is defined as a first side and another side is defined as a second side, the first cover material is disposed from a position between a shoulder region on the second side and the tire equatorial plane to a shoulder region on the first side. The second cover material is disposed from a position between the shoulder region (Ash) on the first side and the tire equatorial plane to the shoulder region on the second side. The first cover material and the second cover material have an overlapping portion at a position where positions in the tire width direction become positions identical to one another.

A tyre includes a tread portion being provided with a pair of shoulder circumferential grooves on an outer surface thereof and a tread reinforcing layer disposed in the tread portion. The tread reinforcing layer includes a circumferential belt layer having a plurality of first reinforcing cords oriented along a tyre circumferential direction. The circumferential belt layer includes a pair of axially spaced first circumferential belt plies extending in radially inner regions of the pair of shoulder circumferential grooves. The pair of first circumferential belt plies is arranged apart from one another at a distance L equal to or more than 20 mm in a tyre axial direction.

A pneumatic tire has a tread reinforcing layer comprising a net structure formed from a tape of rubber coated reinforcing cord(s). The net structure comprises first oblique segments and second oblique segments of the tape which intersect with each other, forming interspaces therebetween. The first oblique segment has a first axial outer part in which the angle of the tape with respect to the tire circumferential direction decreases toward one end in the tire axial direction of the net structure. The second oblique segment has a second axial outer part in which the angle of the tape with respect to the tire circumferential direction decreases toward the above-said one end of the net structure. The first axial outside part is connected to the second axial outside part directly or through a circumferential segment of the tape.

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 tyre includes a tread portion provided with circumferential grooves to form circumferential land portions, a belt layer, and a band layer disposed outwardly in the tyre radial direction of the belt layer. The band layer includes a first layer covering an entire width of the belt layer, and second layers disposed outwardly in the tyre radial direction of the first layer and arranged separately in a tyre axially direction from one another. Each second layer is located radially inwardly of a respective one of the circumferential land portions. In each circumferential land portion, the second layer has at least one axial edge that is away at a distance (A) of equal to or more than 3.0 mm in the tyre axial direction from a groove bottom of one of the circumferential grooves nearest to the at least one axial edge.

In order to improve shock burst resistance performance while suppressing a decrease in separation resistance performance, a pneumatic tire includes a tread portion, a belt layer, and a belt cover layer. The belt layer is disposed in the tread portion. The belt cover layer is disposed on an outer side in a tire radial direction of the belt layer. The belt cover layer includes: two layers of full covers disposed between shoulder regions on both sides in a tire width direction and layered in the tire radial direction; and a narrow cover formed with a width in the tire width direction narrower than widths of the full covers. The narrow cover is disposed at a position between the two layers of the full covers and on an inner side in the tire width direction than the shoulder regions.

A pneumatic tire includes: a belt layer including a belt cord is arranged; and a belt reinforcing layer in which an organic fiber cord is arranged, the organic fiber cord is a hybrid cord formed by twisting an aramid yarn and a nylon yarn together, and a ratio (Sr/Sc) of a rubber cross-sectional area (Sr) to a cord cross-sectional area (Sc) is 1.5 to 2.0, 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 11 or more.
