A tire for a vehicle wheel includes a carcass, a tread band radially external to the carcass, and a pair of axially distanced sidewalls. The carcass includes at least one carcass ply including ends associated with bead cores. Each bead core is incorporated in a respective bead and each bead includes a bead filler. Each sidewall is disposed, in a radial direction, between the tread band and a respective bead and is disposed in an axially outermost position. Each bead core includes a plurality of windings of a single wire. The plurality of windings is axially arranged side-by-side in a plurality of radially superposed layers, defines a transverse hexagonal section symmetrical with respect to an axis substantially parallel to the radial direction, and includes radially innermost and radially outermost layers. An axial width of the radially innermost layer is greater than an axial width of the radially outermost layer.
