    摘要： A pneumatic tire is produced for off-the-road use having a tread formed from a silica-free rubber tread compound consisting essentially of particular types of rubber, and at least 55 phr of a particular high structure, fine particle carbon black having a CTAB from 130-150 m.sup.2 /g, N.sub.2 adsorption of 140-160 m.sup.2 /g, a tint of 125-140%, a DBPA of 120-140 ml/100 g, and a mean particle diameter of about 24 nanometers; and, from about 4 to about 8 phr of processing oil, antioxidant/antiozonants, curing agents and activators each present in an amount less than 10 phr. The result is a tire with substantially better cutting and chipping resistance than an identically produced tire with a tread containing silica in combination with a carbon black having essentially the same mean particle diameter but lower structure, without any noticeable loss in treadwear, or with an improvement in treadwear, that is, less loss due to treadwear.

    摘要： A predominantly styrene-butadiene copolymer rubber (SBR) tire tread compound may be reinforced with a special high structure carbon black designated herein as a N103, having a relatively high volatiles content (as indicated by its iodine number), and a superfine particle size smaller than about 20 nanometers (nm), a DBPA greater than 120 cm.sup.3 /100 g carbon black, and an I.sub.2 No in the range from 130-160 mg/g, in an oil extended tread compound in which there is at least 30 parts of processing oil per 100 parts of rubber; the presence of this N103 black in a major amount relative to the total amount of high structure black, is essential.

    摘要： A pneumatic radial tire having reduced rolling resistance is provided. The tire has a novel tread composition comprising 100 parts by weight of rubber of which at least 90 parts by weight is cis-polyisoprene. The tread composition also has less than 10 parts by weight of processing oil and from 30 to 60 parts by weight of carbon black wherein said carbon black has a particle size greater than about 35 millimicrons and a dibutyl phthalate absorption value greater than 100.

    摘要： Bonding of rubber or other plastics to mineral reinforcements such as silica pigment is brought about by a mercapto alkyl silane without production of foul odors from the mercapto compound by preliminary reversible coupling of the mercapto compound with a material capable of addition reaction such as toluene diisocyanate.

    摘要： An improved radial tire is reinforced with at least two carcass plies of radial rubberized cords wherein a radial inner or first ply extends continuously from one bead portion to another bead portion through the sidewall areas and across the crown of the tire and a radial outer or second ply in continuous contact with the inner ply has two sections disposed such that the second ply is discontinuous or interrupted in the crown area. The second ply is also foreshortened in the bead portion of the tire rather than being wrapped around the bead. An inner liner is also in constant contact with the inner ply from bead portion to bead portion without being wrapped therearound.
