## Abstract

Pneumatic vehicle tire includes a carcass, a belt with at least three belt plies arranged one on top of the other in a radial direction and being arranged radially outside the carcass and a profiled tread arranged radially outside the belt. The at least three belt plies include a radially inner belt ply and a radially outer belt ply are working plies having parallel strength members that are embedded in rubber so that, when viewed in a circumferential direction of the vehicle tire, the strength members of the radially inner belt ply have an opposing axial direction of inclination to the strength members of the radially outer belt ply. A generally zero-degree ply is arranged between and in contact with the two working plies.

## Claims

### Claim 1

A pneumatic vehicle tire comprising:
a carcass;
a belt, comprising at least three belt plies arranged one on top of the other in a radial direction, being arranged radially outside the carcass; and
a profiled tread arranged radially outside the belt,
wherein the at least three belt plies comprise a radially inner belt ply and a radially outer belt ply are working plies having parallel strength members that are embedded in rubber so that, when viewed in a circumferential direction of the vehicle tire, the strength members of the radially inner belt ply have an opposing axial direction of inclination to the strength members of the radially outer belt ply,
wherein the at least three belt plies comprise a generally zero-degree ply arranged between the two working plies, the generally zero-degree ply having parallel strength members that are embedded in rubber and oriented at an angle β to the circumferential direction in which 0°≤β≤5°, and
wherein the strength members of one of the two working plies are oriented at an angle α to the circumferential direction in which 10°≤α<45°, and the strength members of an other of the two working plies are oriented at an angle γ to the circumferential direction in which 45°≤γ≤90°, further comprising:
an additional belt ply having parallel strength members that are embedded in rubber, the additional belt ply being arranged radially outside the radially outer belt ply; and
another belt ply having parallel strength members that are embedded in rubber, the another belt ply being is arranged radially inside the radially inner belt ply and between the carcass and the radially inner belt ply,
wherein the another belt ply is arranged directly adjacent the carcass,
wherein the strength members of the another belt ply are oriented at an angle ε to the circumferential direction in which 45°≤ε≤90°,
wherein an axial extent of said another belt ply is different from an axial extent of the additional belt ply,
wherein an axial extent of the additional belt ply is different from an axial extent of the two working plies and is different from an axial extent of the generally zero-degree ply arranged radially between the two working plies, and
wherein an axial extent of the generally zero-degree ply arranged radially between the two working plies is smaller than an axial extent for each of the two working plies.

### Claim 2 (depends on 1)

The pneumatic vehicle tire according to the features of claim 1, wherein the axial extent of the generally zero-degree ply is at least 10 mm smaller than the axial extent for each of the two working plies.

### Claim 3 (depends on 1)

The pneumatic vehicle tire according to the features of claim 1, wherein both axial ends of the generally zero-degree ply end within an axial extent region of each of the two working plies.
