    摘要： The present invention is directed a pneumatic agricultural or industrial tire (20) comprising a casing (21) and a rubber tread (32A, 32B, 34) disposed radially outwardly of the casing (21), the tread having an inner tread (34) and a plurality of tread lugs (50) projecting radially from the inner tread (34), said casing (21) having at least one component (22, 26, 28), 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 75 to 15 parts by weight of polybutadiene and 25 to 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;
        0.1 to 8 parts by weight of at least one accelerator selected from benzothiazoles and dithiophosphates and exclusive of sulfenamides;
        1 to 15 parts by weight of at least one resin selected from phenolformaldehyde resins, aliphatic cyclic hydrocarbon resins, and aromatic hydrocarbon resin;
        10 to 150 parts by weight of a filler selected from the group consisting of carbon black, silica, and starch/plasticizer composite filler; and
        0.3 to 3 parts by weight of sulfur;
        wherein each lug has a width in a range of from 2 cm to 10 cm and length in a range of from 2 cm to 60 cm, and a height in a range of from 2 cm to 10 cm, and wherein the tread has a net-to-gross ratio in a range of from 15 to 40 percent as measured around the entire 360° circumference of a normally inflated and normally loaded tire contacting a flat hard surface.

    摘要： A pneumatic tire is disclosed having 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 formula:

             R f ― R 1 ― SiX 3-x ― R 2 x      I

    wherein R f is a perfluorinated group optionally containing one or more heteroatoms; R 1 is a divalent alkylene group, arylene group or mixture thereof, substituted with one or more heteroatoms or functional groups, containing 1 to 16 carbon atoms; R 2 is a lower alkyl group; X is a halide, a lower alkoxy group or an acyloxy group; and x is 0 or 1.
