The present invention relates to a two piece pneumatic tire comprising a carcass and a removable tread belt disposed radially about the periphery of the carcass, the tread belt and carcass meeting at an interface between a radially outermost surface of the carcass and a radially innermost surface of the tread belt, wherein at least one of the radially outermost surface of the carcass and the radially innermost surface of the tread belt comprise a self lubricating rubber composition, the self lubricating rubber composition comprising at least one rubber and from 1 to 50 phr of at least one additive selected from alcohols of formula I, esters of formula II, or amides of formula III wherein Rand Rare independently selected from C-Calkyl, C-Calkenyl, or C-Calkadienyl.

Two-piece tire

The present invention relates to a pneumatic tire having a pair of spaced apart bead components, a connecting carcass between said bead components, and a rubber chafer positioned around at least a portion of each of said bead components and intended for contacting a rigid rim of a wheel, wherein said chafer comprises a self lubricating rubber composition, the self lubricating rubber composition comprising at least one rubber and from 1 to 50 phr of at least one additive selected from alcohols of formula I, esters of formula II, or amides of formula III wherein Rand Rare independently selected from C-Calkyl, C-Calkenyl, or C-Calkadienyl.

Tire with chafer

The present invention relates to a two piece pneumatic tire comprising a carcass and a removable tread belt disposed radially about the periphery of the carcass, the tread belt and carcass meeting at an interface between a radially outermost surface of the carcass and a radially innermost surface of the tread belt, wherein at least one of the radially outermost surface of the carcass and the radially innermost surface of the tread belt comprise a self lubricating rubber composition, the self lubricating rubber composition comprising at least one rubber and from 1 to 50 phr of at least one additive selected from alcohols of formula I, esters of formula II, or amides of formula III wherein Rand Rare independently selected from C&#x2013;Calkyl, C&#x2013;Calkenyl, or C&#x2013;Calkadienyl.

A two-piece tire assembly has a removable tread beltfor installing about the circumference of a tire carcass. The tread belt has a pair of lateral ends each axially extending beyond the inflated unloaded carcassat the circumferential surface by a distance of at least% of the width as measured at the tread beltand carcassinterface. The carcasshas an abrasion resistant rubber layerat the tread belt interface. The tread beltalso has the abrasion resistance tread compoundat the carcassinterface. The tread belthas a tread portionthat includes a tread capA and a tread baseB.

This invention relates to a novel class of polymeric resins which have a softening point ranging from about 50&deg; C. to about 220&deg; C. and a molecular weight ranging from about 500 to about 42,000. The resins consist essentially of the polymers which result from the polymerization reaction between dicyclopentadiene and limonene. The polymeric resins are particularly useful in improving traction of the rubber when used in tire treads.

Polymeric dicyclopentadiene/limonene resin

A pneumatic tire with a rubber tread which contains at least three resins with spatially-defined softening point ranges.

This invention describes the use of liquid block isoprene-butadiene copolymers of approximately 25,000 to 100,000 .sub.v molecular weight, and which comprises 10 to 90% by weight isoprene and 90 to 10% by weight butadiene. This material is added to a rubber compound that contains natural rubber, isoprene rubber, styrene butadiene rubber and butadiene rubber, or blends thereof, the sum of which is equal to or greater than 50 phr of the entire rubber content formulation. The liquid block copolymer is used at low levels, typically 1.5 phr to 15 phr. The invention also includes tires with at least one component composed of such rubber composition such as a tire tread.

Tire with tread made with liquid block copolymer

This invention relates to a pneumatic rubber tire having a rubber sidewall with at least a portion of its outer surface being composed of white rubber devoid of carbon black reinforcement and composed of an elastomer composition prepared as a combination of EPDM, chlorobutyl rubber, diene-based elastomers and liquid EPDM. The liquid EPDM component replaces at least a portion of a traditionally used naphthenic/paraffinic processing oil.

Tire with white sidewall

There is disclosed a method for adhering rubber to reinforcing materials which comprises embedding a textile fiber or metal reinforcing material in a vulcanizable rubber composition comprising rubber, a vulcanizing agent, reinforcement, a methylene donor, a methylene acceptor and a maleic anhydride functionalized triblock copolymer having polystyrene endblocks and poly-(ethylene/butylene) midblocks.
