A self-inflating tire assembly includes an air tube mounted within a tire sidewall or chafer groove. The air tube is in contacting engagement with opposite angled groove surfaces surrounding the air tube. A segment of the air tube is flattened from an expanded diameter to a flat diameter by bending and compression of the groove in a rolling tire footprint to force air evacuated from the flattened segment along a tube air passageway. A coverstrip overlays and seals the groove and provides an abrasion resistant surface on the exterior of the tire. The coverstrip is made from a vulcanizable rubber composition comprising from 50 to 80 phr of a polybutadiene, from 50 to 20 phr of natural rubber, and from 0.1 to 5 phr of a vulcanization modifier.

Air maintenance tire

The present invention relates to a pneumatic tire having a non-spliced film innerliner comprised of a plurality of film layers where said film layers are of varied film moduli physical properties.

Tire with non-spliced multilayered film innerliner

The present invention relates to a pneumatic tire having an alloy film innerliner with a rubber reinforced spliced overlapping ends.

Tire with spliced film innerliner

The invention relates to a rubber composition and its preparation having a crosslink distribution, particularly at least two types of crosslinks, its preparation, and an article of manufacture, including a tire, having a component of such rubber composition. In one embodiment the crosslink distribution can be a controlled crosslink distribution of at least two types of crosslinks. In one embodiment, such crosslink distribution relates to an inclusion in the rubber composition of an additive to promote the crosslink distribution where the additive itself has a part of the desired crosslink characteristics. The distributed crosslinks can be of different types including different length, different chemistry, and connecting different points on the crosslinked rubber chains. The distributed crosslinks can be present in different concentrations in the rubber composition. The crosslink distribution can be random or in the nature of a gradient change between domains of different crosslinks. The properties of the rubber composition can be varied by adjustment of such distributed crosslinks to promote various physical properties such as, for example, its viscoelastic properties, tear strength, abrasion resistance and green strength.

Rubber composition having a crosslink distribution, its preparation and article with component

The invention relates to a rubber composition and its preparation having a crosslink distribution, particularly at least two types of crosslinks, its preparation, and an article of manufacture, including a tire, having a component of such rubber composition. In one embodiment, such crosslink distribution relates to an inclusion in the rubber composition of an additive to promote the crosslink distribution where the additive itself has a part of the desired crosslink characteristics. The crosslink distribution can be random or in the nature of a gradient change between domains of different crosslinks.

The invention relates to a cured rubber composition, its preparation and a tire with a component of such rubber composition. A reinforcing resin is used to promote stiffness for the cured rubber composition. The elastomer for the rubber composition is primarily comprised of at least one isoprene-containing elastomer.

Rubber composition, preparation and tire with component

The invention relates to rubber compositions containing a treated silica, particularly sulfur cured rubber compositions, and articles of manufacture having a component thereof such as, for example tires. The invention particularly relates to synthetic amorphous silica, particularly a precipitated silica, treated with a combination of allylsilane and dialkylsilane.
