  • Radial tire
    Patent number: 5388626
    Abstract: A radial tire which mitigates reactions when running across protrusions to thereby avoid damage to the vehicle. The tire prevents rim touch, an indirect contact of the inner face of the tread portion with a flange of the rim or a direct contact of the tread portion with the bead portion. The tire has sidewall portions which are bulged-out to satisfy certain equations. An increase in sidewall thickness and carcass rigidity is avoided with the radial tire.

  • Radial pneumatic tire having contoured zones in the sidewalls
    Patent number: 5280817
    Abstract: The present invention relates to a radial pneumatic tire having a contoured zone located in each of the sidewalls of the tire. The contoured zone improves the sidewalls ply durability and decreases upper sidewall circumferential ply-wire breakage, also known as zipper-break.

  • Cut resistant tire with embedded oblong fibers
    Patent number: 5173136
    Abstract: A cut resistant pneumatic tire is provided. The tire has embedded in its sidewalls and/or tread, short lengths of adhesive coated monofilament nylon fibers. Adhesion between the rubber of the tire and the adhesive coated fibers provides a stiffer, more cut resistant composition.

  • Drag racing tire
    Patent number: 5137069
    Abstract: The ratio of the tire sidewall measured diametrically through the center is such with respect to the diameter of the wheel on which the tire is mounted that tire growth is reduced. The wheel diameter is larger than conventional drag racing tire wheels and the sidewall dimension is less while the diameter of the tire and the tread width remains substantially unchanged.

  • Pneumatic vehicle tire having bead portions that can be turned in and bead cores embedded in the bead portions
    Patent number: 5103886
    Abstract: A pneumatic vehicle tire having bead portions that can be turned in is provided. Embedded in the bead portions are bead cores built up from load-carrying elements that essentially extend in a circumferential direction. The load-carrying elements are disposed in such a way that each element is in contact with at least two other load-carrying elements. The load-carrying elements, at least to the extent that they are coated with rubber, have a surface that prevents adhesion to vulcanized rubber. The load-carrying elements of a bead core are disposed in layers, with the elements of the outer layer being disposed in such a way that they do not contact one another.
