Abstract: A pneumatic tire including at least one component having a rubber composition including at least one diene based elastomer and a silica that prior to mixing with said elastomer is prehydrophobated with a fluorinated silane of the following formula: Rf—R1—SiX3-x—R2x ??I wherein Rf is a perfluorinated group optionally containing one or more heteroatoms; R1 is a divalent alkylene group, arylene group or mixture thereof, substituted with one or more heteroatoms or functional groups, containing about 1 to about 16 carbon atoms; R2 is a lower alkyl group; X is a halide, a lower alkoxy group or an acyloxy group; and x is 0 or 1.

Abstract: The present invention is directed a pneumatic agricultural or industrial tire comprising a casing and a rubber tread disposed radially outwardly of the casing, the tread having an inner tread and a plurality of tread lugs projecting radially from the inner tread, said casing having at least one component, said component comprising textile cord and a rubber composition in contact with the textile cord, the rubber composition comprising 100 parts by weight of at least one diene based elastomer, including from about 75 to about 15 parts by weight of polybutadiene and about 25 to about 85 parts by weight of at least one additional diene based elastomer selected from the group consisting of styrene-butadiene rubber, synthetic polyisoprene and natural polyisoprene; about 0.

Abstract: The present invention is directed to a pneumatic tire having at least one component, the at least component including a rubber composition, the rubber composition including a diene based elastomer and 10 to 100 parts by weight, per 100 parts by weight of elastomer, of a nanozeolite having a particle size of less than 1000 nm and a negative coefficient of thermal expansion over at least part of the temperature range of 0° C. to 200° C.

Abstract: The present invention relates to pneumatic tire having a component including exfoliated graphite intercalated with an elastomer, and at least one additional diene based elastomer.

Abstract: The present invention provides a tire comprising a polyester copolymer, the polyester copolymer comprising predominantly polyester segments and an oxygen scavenging amount of polyolefin oligomer segments.

Abstract: This invention relates to a tire having a component of a rubber composition which contains a carbonaceous filler as a composite comprised of a disturbed crystalline structure which contains synthetic cubic (diamond) crystalline phase(s) combined with a significant amorphous phase content and which may also contain graphitic (hexagonal) crystalline phases. The crystalline phases are of a disturbed crystalline structure. The carbonaceous filler composite may therefore sometimes be referred to as a “disturbed crystalline/amorphous carbon material”. Such carbonaceous filler composite may be a product of, for example, an explosive detonation of a carbon-containing, oxygen-deficient explosive. Reinforcement of rubber compositions for components of tires is provided as a combination of such carbonaceous disturbed crystalline/amorphous carbon material together with rubber reinforcing carbon black aggregates and/or synthetic amorphous silica, and optionally with starch/plasticizer composite and/or short fibers.

Abstract: There is disclosed a pneumatic tire having a rubberized component comprising: (a) 100 parts by weight of at least one rubber containing olefinic unsaturation; and (b) 1 to 50 phr of a dendrimer.

Abstract: The present invention is directed a pneumatic agricultural or industrial tire comprising a casing and a rubber tread disposed radially outwardly of the casing, the tread having an inner tread and a plurality of tread lugs projecting radially from the inner tread, said casing having at least one component, said component comprising textile cord and a rubber composition in contact with the textile cord, the rubber composition comprising

Abstract: There is disclosed a pneumatic tire having a rubber component comprising a sulfur cured rubber composition composed of, based on 100 parts by weight of rubber (phr): (a) 99 to 50 parts by weight of a first rubber containing olefinic unsaturation; and (b) 1 to 50 parts by weight of a second rubber which is different from said first rubber and which is an elastomeric block copolymer of (1) from 15 to 65 percent by weight, based on the total block copolymer, of butadiene, and (2) from 35 to 85 percent by weight, based on the total block copolymer, of styrene, which block copolymer has: (a) at least two blocks A which have polymerized units of styrene, a glass transition temperature Tg above 25° C.
