    Abstract: A tire includes first and second laterally spaced sides and a tread interposed between the first and second sides. The tread includes a tread surface having at least one groove therein, the at least one groove including facing, first and second sidewalls separated by a groove bottom surface. A first pocket region of recessed serrations extends over at least a portion of the first sidewall and a second pocket region of recessed serrations extends over at least a portion of the second sidewall. The serrations of the first and second pocket regions are staggered in a circumferential direction relative to one another.

  • Patent number: 11220078
    Abstract: A combination of first and second plugs for a tire mold includes associated first and second receivers/jackets. Fasteners secure the receiver to an associated tire mold. A securing member extends from the receiver into the cavity of the first receiver to retain the first plug therein. The first plug is contoured and dimensioned for mating receipt in the first receiver cavity. The second plug is likewise contoured and dimensioned for mating receipt in the associated second receiver cavity, but will not be accepted in the first receiver. A tool is provided to facilitate insertion and removal of the first and second plugs, and limit the potential for damage to the associated tire mold.

  • Patent number: 11077720
    Abstract: Different sized, first and second domes are stacked, one atop the other on the surface of a rib or tread block of a tire. The lower, first dome spans a larger area of the tread. In one embodiment, the first dome covers the entire tread block or extends laterally across a rib. The upper, second dome is located on top of the first dome and spans only a portion of the first dome. The domes are either concentric or offset, or can be elliptical with the major axes of the ellipses oriented such that the major axes are optimized for a specific tread block or rib geometry. The major axes of the ellipses may be oriented parallel to or perpendicular to an axis of stiffness of the tread block or rib.

  • Patent number: 11053326
    Abstract: A method for stabilizing a natural rubber such as guayule. The method includes the step of introducing at least one of an Extraction Curves for Guayule Rubber Samples amine and a phenolic anti-oxidant, such as MADA, to a latex form of the rubber under conditions such that the anti-oxidant becomes chemically bound to the rubber. The method includes the further step of subsequently treating the rubber to remove at least a substantial portion of entrained resins. The method can yield a rubber composition of, for example, guayule rubber and including an anti-oxidant chemically bound thereto. The resultant rubber can be suitable for use in tire construction.
