ABSTRACT:
A pneumatic vehicle tire with an annular bead core consisting of multiple layers of wound wire has a bead core with a cross-section that, based on a hexagonal cross-sectional area defined by a radially outer and a radially inner side, a radially outer and axially outer side, a radially outer and axially inner side, a radially inner and axially outer side, and a radially inner and axially inner side, has a cross-sectional portion that is free of wire windings. The cross-sectional portion has a triangular or quadrangular shape. The triangular shape is delimited by the radially outer side and the radially outer and axially outer side and a connecting line between free ends of the radially outer side and the radially outer and axially outer side. The quadrangular portion is delimited by the radially outer side and the radially outer and axially outer side, a section of the radially inner and axially outer side, and a connecting line between a free end of the radially outer side and an end point of the section of the radially inner and axially outer side. When based on a rectangular cross-sectional area, defined by n rows and m layers of windings and having a radially outermost corner, a cross-sectional portion free of windings has a triangular shape.
