This invention relates to a light duty tire (e.g. passenger tire or light duty truck tire) designed for a load bearing capacity of a maximum of 3,500 pounds (1587 kg) with a tread of a cap/base construction with at least one underlying silica-rich, cis 1,4-polyisoprene rubber based intermediate transition rubber layer to promote a reduced internal heat generation for the light duty tire and to therefore promote a light load carrying light duty tire which is more durable for the long haul. Such light duty tire tread is intended for use with light loads in which internal heat may be generated within the tire, including the tire tread, during use.

This invention relates to a heavy duty tire (e.g. heavy duty truck tire) designed for a load bearing capacity of at least 4,000 pounds (1814 kg) with a tread of a cap/base construction with at least one underlying silica-rich, cis 1,4-polyisoprene rubber based intermediate transition rubber layer to promote a reduced internal heat generation for the heavy duty tire and to therefore promote a load carrying heavy duty tire which is more durable for the long haul. Such heavy duty tire tread is intended for use with heavy loads in which internal heat is expected to be generated within the tire, including the tire tread, during use.

The present invention provides for oxygen scavenging materials and uses thereof for reducing oxygen content in an air cavity of a mounted tire, such as to reduce oxidation of a tire. The oxygen scavenging material can include a metal or metal-based material, an antioxidant, or microorganism. In one example, the oxygen scavenging material may be situated or secured within a tire cavity or secured to the tire rim of a wheel prior to mounting of the tire on the rim. Accordingly, the tire is mounted on the tire rim to define an air cavity with the oxygen scavenging material being located therein. The air cavity is be filled with air comprising oxygen to a desired internal air pressure with the oxygen scavenging material being provided in an amount sufficient for reducing oxygen content in the air cavity, such as to reduce oxidation of the tire thereby increasing the lifespan thereof.

This invention relates to preparation of nanocomposites comprised of elastomer and a dispersion of an at least partially exfoliated water swellable clay and to rubber compositions containing such nanocomposite and articles of manufacture which contain at least one component thereof. The nanocomposite is prepared by addition of a water suspension of water swellable clay particles to an anionic aqueous emulsion of elastomer particles to form a mixture to which an amine having at least two amine centers is added to intercalate and at least partially exfoliate the water swelled clay particles by an ion exchange within the galleries of the multilayered clay with cation exchangeable ion(s) and to aid in coagulating the elastomer and resultant clay particles to form said nanocomposite.

A bond of a rubbery component to a virgin surface of a tire's cured innerliner which virgin surface has never been contaminated by the remnants of a release agent left after buffing with a wire brush and solvent-cleaning the cured innerliner, is unexpectedly stronger than a bond of the component to the contaminated but 'cleaned surface', cleaned as indicated. As an alternative, buffing with a wire brush results in a textured surface that impairs adhesion of a balance pad. Therefore, a pneumatic tire is provided with a virgin surface protected against contamination by a release agent at the curing temperature of the tire; protection is provided by a self-supporting barrier film of sulfur non-vulcanizable, expandable, thermoformable synthetic resinous material; and, a method is provided for maintaining a virgin cured surface within all or part of either the exterior or interior of a pneumatic tire's rubber carcass which is conventionally cured. The barrier film which is substantially inextensible at ambient temperature, is removable without tearing into pieces from the protected surface of the cured tire. When the interior surface is provided by an innerliner, any component to be included within the interior of the carcass may be adhesively secured to the virgin surface of the innerliner more securely than has been heretofore possible.

Adherent, removable barrier film for tire carcass

An applique having a vulcanizable adhesive layer is co-cured on a rubber article by precuring the applique of predominantly pale natural rubber optionally imprinted with a bar code; coating the upper surface of the applique with a protective self-supporting film of polyamide less than 0.050 mm (2 mils) thick, or a non-self-supporting film of polyurethane less than 25.4 &#x3bc;m, 0.0254 mm (1 mil) thick; adhering the applique to the article at a chosen location; curing the article in a curing mold; and, removing a cured article from the mold with the protective film adhering to the surface of the applique, the surface of which is essentially free from visually observable cracks. The hot flow of rubber in the curing mold does not substantially change the location of the applique which is embedded in the article. If the film does not remain adhered to a cured tire and drops into the mold, it is difficult to retrieve and, when a subsequent article is cured in the same mold, results in a scrap tire.

The invention relates to an endless vehicular rubber track. The invention particularly relates to such track having hard rubber guide lugs with a softer guide support layer. It is to be appreciated that such guide lugs may also be positively driven drive lugs. The invention further relates to a vehicle having such track.

The present invention relates to a tire with a carcass ply and/or circumferential carcass belt component comprised of a natural rubber-rich diene-based rubber composition which contains a dispersion of precipitated silica reinforcement, with coupling agent, to a substantial exclusion of carbon black.

The invention relates to an endless vehicular rubber track designed for extreme cold temperature working environment. The invention particularly relates to such track having a combination of tread, supporting carcass and guide lug components of rubber compositions intended for such purpose.

The present invention relates to tires and vehicular tracks having minimal-marking rubber treads and particularly to skid steering, fixed axle, tire/wheel or track assemblies where said tire or vehicular track has a minimal-marking tread. In particular, such rubber tread has a surface intended to be ground-contacting which is also intended to be minimal-marking and having suitable physical properties for a tire tread.

The invention relates to a pneumatic rubber tire with an outer, circumferential tread wherein said tread has a tread configuration comprised of spaced apart, raised lugs designed to be shock absorbingly ground contacting, wherein said tread and lugs are comprised of rubber selected from butyl rubber, halobutyl rubber or isobutylene-derived rubber. Said tire may also contain sidewalls comprised of one or more of such rubber. Thus, such tread is a combination of specific structural configuration and specific rubber composition to create a shock absorbing effect.

A pneumatic aircraft tire has carcass plies and/or breaker plies which are reinforced by high modulus reinforcement cords embedded in a rubber composition that contains no free amines and has a 300% modulus of 12-18 MPa and a minimum tensile strength of 23 MPa as tested per ASTM D412, and a T90 of between 30 and 40 minutes at a reference temperature of 135 degrees C. as tested per ASTM D2084. The cords in the carcass plies and/or breaker plies have a tenacity of 6.6 to 8.2 g/denier, an initial modulus of 120 to 280 g/denier, an elongation at break of 8 to 18% and a shrinkage of not greater than 3%. Polyester reinforcement cords are preferred.

A silica reinforced solventless adhesive composition or cushion comprises a blend of rubber, silica, a silica coupling agent, an optional tackifier, and low or nil amounts of carbon black. The elastomeric adhesive composition can be utilized with various other rubber layers to adhere a cured or uncured tire tread to a cured tire casing. The elastomeric adhesive composition has good blowout resistance and a very low, final blowout test temperature.
