  • Runflat tire with dual-modulus underlay
    Patent number: 6371182
    Abstract: A pneumatic radial ply runflat tire (200) has a tread (210), belt structure (212), a carcass (216), and an underlay (234) disposed between the belt structure and the carcass. The carcass (216) comprises two sidewalls (226), two beads (220), and one or more radial plies (222,224). The tire (200) is characterized by the underlay (234) having reinforcement cords (236) with turns aligned parallel to the tire's equatorial plane, the cords (236) exhibiting negligible modulus of elasticity (“modulus”) below a threshold elongation and high modulus above the threshold elongation. The underlay (234) stiffens the tire during runflat operation but not during normal inflated operation.

  • Method of making a tire bead core assembly
    Patent number: 4662961
    Abstract: A pneumatic tire and a method of constructing a tire bead for the same, in which the tire has a bead portion which is reinforced by a bead core of wire running around the bead portion and the wire is housed in a circular elastomeric support which forms a cradle in which the wire is located. The bead can be made by winding wire around the preformed elastomeric cradle.
