Abstract

Vehicle pneumatic tire with belt and carcass. An inner working ply of the belt has first parallel steel strengtheners embedded in rubber oriented at an angle “α” relative to a circumferential direction and satisfy: 10°≦α≦45°. An outer working ply of the belt has second parallel steel strengtheners embedded in rubber oriented at an angle “γ” and satisfy: 10°≦γ≦45°. The inner working ply has a greater axial length. The angles “α” and “γ” have opposite inclination. Another belt ply is arranged between the inner and outer working plies and has third parallel strengtheners embedded in rubber oriented at an angle “β” and satisfy: 0°≦β≦5°. The first and second strengtheners have a breaking force F greater than 1800 N and at 10% of the breaking force F, an extension D satisfies 0.22%≦D≦0.4%.
