A racing tire comprising a tread having a new tread thickness of no greater than about 0.375 inch. The tread defines a running surface that includes a first circumferential portion of a first rubber compound and a second circumferential portion of a second rubber compound situated adjacent one another. The first rubber compound has a greater stiffness than the second rubber compound so as to provide the tread with greater wear resistance along the first circumferential portion, and the second rubber compound provides the tread with greater traction along the second circumferential portion. The tread may be substantially free of a tread pattern. The second rubber compound may have a greater DIN abrasion value than the first rubber compound. The second rubber compound may have a higher tan delta at 100&#xb0; C. and/or a higher J&#x2033; traction value than the first rubber compound.

Zoned tread for racing tires

The invention relates to a tire having a tread with a cellular rubber running surface to promote a fast wearing tread running surface designed to expel internally heated tread rubber.

Tire with cellular rubber tread running surface

This invention relates to a pneumatic tire with an outer, running surface containing, circumferential tread comprised of a styrene/butadiene (SBR) rich rubber composition containing two SBR's with spaced apart glass transition temperatures (Tg's), one of which is a functionalized SBR with a functional group reactive with hydroxyl groups on a precipitated silica, together with a combination of at least three resins with spaced apart softening points. The filler reinforcement is a combination of precipitated silica and specialized rubber reinforcing carbon black.

Tire with rubber tread containing combination of resin blend and functionalized elastomer

Pneumatic rubber tire with an outer, circumferential tread comprised of specialized cis 1,4-polybutadiene rubber based silica/carbon black reinforced rubber composition.

Tire with tread of polybutadiene rubber

The invention relates to a tire having a tread which contains coal dust to promote a fast wearing tread running surface designed to expel internally heated tread rubber.

Tire with tread

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.

Aircraft tire

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.

Preparation of nanocomposite of elastomer and exfoliated clay platelets, rubber compositions comprised of said nanocomposite and articles of manufacture, including tires
