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

A pneumatic rubber tire having an integral rubber innerliner containing anchored hollow glass microspheres.

Pneumatic tire having air retention innerliner containing anchored glass microspheres

This invention relates to a pneumatic rubber tire having a puncture resistant rubber sidewall. The said tire sidewall is comprised of an outer, visible annular configured sidewall rubber layer and an inner (non-visible) annular configured sidewall rubber layer integral with and underlying said outer sidewall rubber layer, wherein said inner sidewall rubber layer contains a dispersion of short fibers, wherein said short fibers are substantially aligned in parallel relationship to each other and substantially parallel to the said annular configuration of said inner sidewall rubber layer. In a further aspect of the invention, said tire is comprised of a carcass which contains a rubber carcass ply comprised of a rubber encapsulated cord reinforcement of a plurality of cords wherein said cords are positioned in a radially disposed spaced apart substantially parallel relationship to each other, wherein said rubber carcass ply is integral with and underlies said inner rubber sidewall layer and wherein said short fibers of said inner rubber sidewall layer are substantially aligned in a perpendicular direction to said cords of said underlying carcass ply.

Tire with puncture resistant sidewall

Pneumatic rubber tire having at least one component of a polybutadiene-rich rubber composition comprised of a blend of a continuous phase of a specialized cis 1,4-polybutadiene rubber and a dispersed phase comprised of a composite of styrene/butadiene elastomer which contains a dispersion of at least partially exfoliated, intercalated, clay platelets, wherein said cis 1,4-polybutadiene rubber and styrene/butadiene elastomer have spatially defined glass transition temperatures, wherein said blend contains amorphous silica and carbon black reinforcement. Such tire component may be, for example, a circumferential tread having a running surface intended to be ground-contacting or a sidewall insert.

A pneumatic tire having a rubber sidewall including

Pneumatic tire

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.

Runflat tire with sidewall component containing high strength glass bubbles

The present invention provides a pneumatic tire, wherein the tire comprises one or more indicia formed from an elastomeric coating comprising an elastomer selected from the group consisting of: a graft-modified fluoroelastomer grafted to a grafting agent; a hydrogenated copolymer of a conjugated diene and an unsaturated nitrile; and a carboxylated hydrogenated copolymer comprising a repeating unit from a conjugated diene, an unsaturated nitrile, and a carboxyl monomer.

Tire with indicia

A pneumatic rubber tire containing at least one electrically conductive cord extending between its bead and tread portions to provide a path of least electrical resistance. The electrically conductive cord is comprised of at least one electrically conductive metal filament spirally wound around a centrally disposed core of at least one organic fiber. The electrically conductive cord does not extend to, and is exclusive of, an outer surface of the tire.

The invention relates to a tire having a tread of a rubber composition with compositional limitations containing minimal, if any, of in situ formed volatile alcohol byproduct. The tread component rubber composition contains a combination or pre-hydrophobated silica reinforcement and siloxane functionalized styrene/butadiene copolymer elastomer. The pre-hydrophobated silica is prepared, prior to mixing with the elastomer(s), by reacting hydroxyl groups (e.g. silanol groups) contained on the surface of a precipitated silica with an alkoxyorganomercaptosilane or with a bis-3(triethoxysilylpropyl)polysulfide which contains an average of from 2 to 4 connecting sulfur atoms in its polysulfidic bridge to form a composite thereof which may optionally include an alkyl silane. The volatile alcohol byproduct (e.g. ethanol) therefrom is thereby removed from the pre-hydrophobated silica composite prior to its introduction into the rubber composition(s).

Tire with low volatile alcohol emission rubber tread with compositional limitations

The invention is directed to a pneumatic tire having a tread including a vulcanizable rubber composition including, expressed as parts by weight per 100 parts by weight of elastomer (phr),

The present invention provides a pneumatic tire comprising raised indicia on a sidewall of the tire, the raised indicia comprising a plurality of superposed layers of a curable elastomer composition.

Tire with raised indicia

The invention relates to a tire of a structural combination of tire tread and sidewall components with compositional limitations containing minimal, if any, of in situ formed alcohol and methyl isobutyl ketone byproducts. The tread component rubber composition contains pre-hydrophobated silica reinforcement. The sidewall component contains low unsaturation EPDM or brominated copolymer of isobutylene and p-methylstyrene and may contain pre-hydrophobated silica reinforcement. The silica reinforcement for said tread and sidewall components is a pre-hydrophobated precipitated silica. The pre-hydrophobated silica is prepared, prior to mixing with the elastomer(s), by reacting hydroxyl groups (e.g. silanol groups) contained on the surface of a precipitated silica with an alkoxyorganomercaptosilane or a combination of an alkoxyorganomercaptosilane and a substituted alkylsilane or with a bis-3(trialkoxysilylalkyl) polysulfide which contains an average of from 2 to 4 connecting sulfur atoms in its polysulfidic bridge to form a composite thereof. The alcohol byproduct therefrom is removed from the composite prior to its introduction into the rubber composition(s). In another aspect of the invention, the connecting sidewall rubber composition, and optionally the tread composition is free of N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine antidegradant (referred herein to as 6PPD) in order to prevent in situ formation of methyl isobutyl ketone byproduct from the reaction of 6PPD with atmospheric oxygen and/or ozone.

Tire with low hydrocarbon emission rubber combination of tread and sidewall components with compositional limitations

The invention relates to a tire having at least one component (e.g. tread) of a rubber composition comprised of a composite of styrene/butadiene elastomer and functionalized styrene/butadiene elastomer containing an internal silanol and/or siloxy group therein with pendent silanol and/or alkoxy groups of a polymodal (e.g. bimodal) molecular weight distribution and a dispersion therein of silica aggregates of which a portion thereof contain a plurality of hydroxyl groups on their surface in a form of geminal hydroxyl groups. In one aspect, said silica aggregates may be pre-treated to reduce said hydroxyl groups on their surface prior to blending with said silanol and/or siloxy functionalized elastomer.

Tire with compound of rubber composition comprised of silanol and/or siloxy functionalized elastomer and silica

A pneumatic rubber tire with a sidewall having an outer visible layer of a rubber composition of a relatively high electrical conductivity, wherein the tire sidewall contains an internal rubber strip of relatively high electrical conductivity. Said internal rubber strip extends radially outward from a rubber chafer component of the tire to a tread base layer component of a rubber tire tread of a cap/base configuration, wherein said chafer and tread base rubber compositions are of a relatively high electrical conductivity. The rubber strip thereby provides a path of increased electrical conductivity relative to said outer visible layer of the tire sidewall extending from the tire chafer to the tread base layer tire components.
