    摘要： This invention relates to a tire comprised of an assembly of uncured rubber components wherein said assembly includes a circumferential uncured pre-formed internal composite comprised of a combination of at least one uncured rubber layer containing metal cord reinforcement with a high sulfur content and at least one adjoining auxiliary buffer layer of uncured rubber layer having a significantly lower sulfur content and without cord reinforcement. The auxiliary buffer rubber layer(s) with the reduced sulfur content is provided to promote tear resistance and sulfur cure reversion resistance for the composite. In a preferred embodiment, the uncured rubber composite is pre-formed prior to its application to and made a part of the tire assembly of components. The tire assembly is thereafter cured in a suitable mold to form a tire.

    摘要： The invention relates to preparation of a high silica reinforcement-containing rubber composition by a method which involves a delayed and divided inclusion of greater than 50 percent of fatty acid salt processing aid to a rubber composition in an internal rubber mixer following completion of addition of precipitated silica and silica coupling agent in a preceding rubber mixing step in an internal rubber mixer. The invention further relates to a resulting rubber composition and to tires having a component thereof such as, for example, a tire tread.
