Claim:
A pneumatic tire comprising a carcass structure extending through a pair of opposing bead portions and an inner liner located inward of the carcass structure, each bead portion comprising a bead core about which is wrapped the carcass structure and a toeguard, wherein the bead core is axially centered in the bead portion, and the thickness of the layers about the bead core, absent the thickness of the carcass structure and the inner liner, at three locations, axially inward and axially outward of a maximum axial thickness of the bead core and radially inward of an axial center of the bead core, are equal, the toeguard extends from radially outward and axially inward of the bead core to radially outward and axially outward of the bead core wherein the bead portion further comprises a bead toe, a bead heel and a bead base extending between the toe and heel, and the bead base is comprised of an axially inner portion and an axially outer portion, wherein the axially outer portion is inclined at an angle greater than 5 degrees relative to a line perpendicular to an equatorial plane of the tire, and the axially inner portion is inclined at an angle at least 5.25 degrees greater than the axially outer portion.
