Claim Text:
1. A pneumatic tire comprising: a carcass; a belt being arranged radially outside the carcass; and a profiled tread arranged radially outside said belt, wherein said belt comprises a radially inner working belt ply and radially outer working belt ply 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 said radially inner working belt ply have an opposing axial direction of inclination to the strength members of said radially outer working belt ply, wherein said belt further comprises a generally zero-degree ply arranged between and in contact with the two working belt plies, the generally zero-degree ply extending axially through a center of said profiled tread and having parallel steel strength members that are embedded in rubber and oriented at an angle β to the circumferential direction in which 0°≦β≦5° and having an axial extent that is smaller than an axial extent for each of the two working belt plies, wherein the strength members of one of the two working belt plies are oriented at an angle α to the circumferential direction in which 10°≦α≦45°, and the strength members of another of the two working belt plies are oriented at an angle γ to the circumferential direction in which 45°≦γ≦90°, and wherein the one working belt ply in which the strength members are oriented at the angle α to the circumferential direction is the radially outer working belt ply, and the other working belt ply in which the strength members are oriented at the angle γ to the circumferential direction is the radially inner working belt ply, and further comprising: another belt ply having parallel strength members that are embedded in rubber, the another belt ply being is arranged radially inside the radially inner working belt ply and between the carcass and the radially inner working belt ply; and an additional zero-degree ply being arranged radially outside said radially outer working belt ply.
