    a pair of annular bead cores, and wherein the annular bead cores have a substantially flat radially inner base, the inner base having a diameter d, and an axial width w,a carcass radially inward of the annular tread, the carcass having one or more cord reinforced plies extending to and wrapped about the bead cores;

    an elastomeric apex adjacent to and extending radially outward from each bead core; and

    a first pair of elastomeric inserts radially inward of the carcass plies one elastomeric insert extending radially inward from each lateral edge of the tread toward each bead core and terminating radially and axially inward of a radially outer portion of the elastomeric apex and the rim comprising;

    a hump and a rim flange, the rim flange having an axially inward surface, the distance between the hump and the axially inward surface of the rim being the bead seat, the bead seat having a width W, the rim having a nominal diameter D, the hump having a diameter DH ; and
