The invention relates to a tire having a circumferential rubber tread of a cap/base construction composed of a cap rubber layer as the tire running surface and an internal base rubber layer underlying said tread cap layer. The said tread cap layer is composed of a primary tread cap portion and one or two lateral tread cap portions of rubber compositions containing precipitated silica and/or rubber reinforcing carbon black reinforcement and wherein the rubber composition of at least one of said lateral tread cap portions contains a dispersion of short carbon fibers. Said primary tread cap portion contains a major portion of the running surface of the tread and is comprised of a silica-rich or carbon black-rich, preferably silica-rich, reinforcement-containing rubber composition, and said lateral tread portion(s) contains a minor portion of the running surface of the tread and is comprised of a silica-rich or carbon black-rich, preferably carbon black-rich, reinforcement-containing rubber composition. Where said primary tread cap portion is comprised of a silica-rich rubber composition, said lateral tread cap portion(s) is comprised of a carbon black-rich rubber composition and visa versa. The said tread cap portions are load bearing portions in the sense of extending from the running surface of the tread radially inward to said underlying tread base layer. In one aspect, the portioned rubber tread cap layer and the rubber tread base layer are co-extruded together to form a unitary composite thereof.

The present invention is directed to a camouflage tire suitable for use in various vehicle use environments wherein it is desirable to reduce or eliminate a viewer's visual perception of the tire against the given environmental background.

Camouflage tire

This invention relates to preparation of rubber compositions comprised of EPDM and conjugated diene-based elastomer, particularly including cis 1,4-polyisoprene rubber, and particularly natural cis 1,4-polyisoprene rubber, blends and pneumatic rubber tire with an outer, visible sidewall layer of a rubber composition comprised of such rubber composition. For such preparation, a combination of at least two diverse EPDM elastomers is used together with a phase mixing process comprised of sequential phase mixing or parallel phase mixing in the sense of reinforcement filler and sulfur curatives.

Preparation of rubber composition comprised of EPDM/polyisoprene rubber blends and tire with sidewall comprised thereof

A pneumatic runflat tire comprising a sidewall component comprising a rubber composition comprising at least one diene based elastomer and from about 1 to about 40 phr of glass bubbles having a crush strength of at least 10,000 psi as measured by ASTM D3102-78 in glycerol.

The colored pattern veneer can be used to make a camouflage tire among other patterns.

Camouflage or otherwise multicolored pattern tire and method of manufacturing

This invention relates to a pneumatic tire with puncture sealing property and a method for preparing such tire. Such tire is prepared by building an uncured butyl rubber-based layer, which contains a peroxide and a dispersion therein of a particulate precured rubber selected from pre resin-cured butyl rubber and/or pre sulfur-cured diene-based elastomer, into an uncured tire and between an innerliner layer and the tire carcass. Upon curing the prepared tire under conditions of elevated temperature, a major portion of the uncured butyl rubber composition is depolymerized to form a tacky material, which contains said dispersion therein of said particulate precured rubber, which has puncture sealant properties. Such layer of depolymerized butyl rubber and dispersed precured rubber particles may be collectively referred to as the sealant layer.

Self-sealing pneumatic tire and preparation thereof

The invention relates to a two part endless vehicular rubber track comprised of a polyurethane based tread component and a rubber carcass component. In one aspect, the tread component may be comprised of a sulfur curable polyurethane or blend of sulfur curable polyurethane and sulfur curable elastomer. The invention includes a vehicle containing such track.
