  • Tire bead geometry
    Patent number: 8578991
    Abstract: 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.
    Type: Grant

  • Method of forming pneumatic radial tire including tread having asymmetric profile
    Patent number: 6758928
    Abstract: By shifting the peak height of the tread on one side of the tire from the centerline (CL), for a tire intended for cambered use on a vehicle and/or exposure to lateral loading, improvements in the footprint shape, pressure distribution, area and footprint shape factor (FSF) are obtained. In an illustrated embodiment, 0.127 cm to 5 cm (deep) of mold material are removed from one side of the centerline (CL) of the crown in a conventional mold, at 15% to 85% of the distance from the centerline to the shoulder area of the mold (one-half inch to five and one-half inches in the illustrated tires), to obtain a mold shape having the designated change in tread peak height.
