PURPOSE: A pneumatic tire for a vehicle is provided to set a cord angle of the belt layer using the same molding process and manufacturing alignment, to improve a durability of a tire by not placing a cutting plane of a cord on an edge of a belt. CONSTITUTION: A pneumatic tire for a vehicle comprises a tread, a sidewall, a bead part, belt layers(14), and cords(5). The belt layer is installed in the lower part of the tread. The cord is inserted in the inner side of each belt layers. The cords are formed as a closed curve. A generation of a crack in the belt is restrained by not having a cutting plane of a steel cord in the belt edge. An angle and a width of the cords composing each layer are freely determined because the cords are independently applied to the each layer.
