Bead filler is present that has a portion radially outward from the bead core and axially inboard from the return casing ply. A stiffener layer is present that has a portion located outboard from the return casing ply. The bead has a first bead layer with a portion between the return casing ply and the stiffener layer, and a second bead layer that has a portion outboard from the stiffener layer. The stiffness of the first and second bead layers is 8 MPa to 14 MPa. The stiffness of the bead filler is less than the stiffness of the first and second bead layers.
