摘要： A pneumatic tire has 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. Each bead portion has a bead toe, a bead base, and a bead heel, the bead base extending between the bead toe and the bead heel. The bead heel has a profile corresponding to a sector of an ellipse or approximates a sector of an ellipse by having a dual radius structure. The bead base may have a dual taper configuration. The bead core may be substantially centered in the bead portion, as determined by the material thickness at three locations about the bead core.

摘要： A pneumatic tire 10 has a carcass ply 12 or plies 12, 14 with a locked tie-in construction and a wrap-around toeguard 18. Each wrap-around toeguard 18 is a non cord reinforced elastomeric unitary strip wound 360.degree. in a singular annular bead. The wrap-around toeguard cord reinforced unitary strip 18 can be formed of a single elastomeric composition having a shore hardness of greater than 40. Alternatively the wrap-around toeguard may additionally include an apex portion 29 and a chafer portion 27 along with the toeguard portion 28, each portion 27, 29 being co-extruded or otherwise hot formed and shaped with the toeguard portion 28 to form the unitary strip 18 and can have distinct elastomeric composition relative to the toeguard portion 28.
