A bead core for a tire, which is substantially rotationally symmetrical about an axis, comprises a plurality of windings of at least one metallic wire with diameter d arranged next to one another in a direction P forming an angle α with the axial direction in a radial sectional half-plane R, on N layers superposed on one another in the radial direction, wherein: α ranges from 0° to 10°; in the sectional half-plane R, the windings form a structure consisting of a base structure and a cap structure, wherein the radially inner base structure in the shape of a parallelogram is directly in contact in the radial direction with the radially outer cap structure in the shape of a trapezium. The product of the diameter d times the number of windings L ranges from 13.0 mm to 25.0 mm, and N is less than or equal to 16.
