Abstract:
The present invention relates to a tire having a rubber tread of a lug and groove configuration and of a co-extruded cap/base construction; wherein the tread cap is of a rubber composition which contains carbon black and is thereby of a black color; wherein a visible surface of at least one groove is of a rubber composition exclusive of carbon black and is of a non-black color and wherein said visible non-black colored rubber composition is a rubber layer which underlies said tread cap. Said visible non-black colored rubber is exclusive of any appreciable portion of, and preferably exclusive of, the surface of said tread lugs intended to be ground-contacting. In one aspect of the invention, said non-black colored rubber composition contains an amorphous precipitated silica reinforcement, preferably a pre-hydrophobated precipitated silica. In another aspect of the invention, said non-black colored rubber composition, and alternately, carbon black containing black colored rubber compositions adjoining said non-black colored rubber composition, is comprised a blend of at least one diene based elastomer and a brominated copolymer of isobutylene and p-methylstyrene together with an organo phosphite.
Abstract:
The invention relates to ground sulfur pre-vulcanized rubber (e.g. recycled cured rubber) which is blended with a pre-formed composite of carbon black and tris (2-aminoethyl) amine following which it is sulfur vulcanized. The invention also relates to articles of manufacture, including tires, which have at least one component as a rubber composition comprised of such treated pre-vulcanized particulate rubber.
Abstract:
This invention relates to a pneumatic rubber tire having a rubber tread of a cap/base construction. More specifically, the invention relates to a tire having a tread with minimized, or inhibited, base peaking.
Abstract:
The present invention relates to a tire with a carbon black-containing, black-colored, circumferential tread of a cap/base construction, wherein said tread cap has a lug and groove configuration and wherein the outer surface of a major portion of said grooves are designed to be ground contacting, and a co-extruded thin outer non-carbon black-containing rubber layer of a non-black color wherein said outer rubber layer is integral with and circumferentially extends from the axial outer edge of said tread cap to include at least of a visible surface of at least one groove in said tread cap. In one aspect, said tread contains a pair of black colored, carbon black reinforced, tread miniwings which extend from the axial outer edge of the tread over a portion of the tire sidewall, wherein said thin outer rubber layer joins said miniwing and wherein said tread cap, tread base, tread miniwings and thin outer layer are co-extruded, co-cured and therefore integral with each other.

Abstract:
The invention relates to an aircraft tire with a tread having a running surface of a rubber composition which contains elastomers of which a major portion is a specialized cis 1,4-polybutadiene elastomer and a minor portion is cis 1,4-polyisoprene rubber and which contains reinforcement filler comprised of a combination of precipitated silica and defined rubber reinforcing carbon black.
Abstract:
Field of Invention The present invention relates to a pneumatic tire having its internal cavity containing a closed cellular rubber which contains a dispersion of at least two diverse carbon blacks to promote an improved path for thermal conductivity with suitable physical properties for the closed cellular foam rubber.
Abstract:
A tire having a core located in a tire cavity and a cured and foamed elastomeric material located in the tire cavity adjacent the core. The core is made of a solid material, a precured and foamed elastomeric material or a hollow rigid structure. The core may be a single piece or fabricated from multiple pieces.
