    摘要： A pneumatic rubber tire with a sidewall having an outer visible layer of a rubber composition of a relatively high electrical conductivity, wherein the tire sidewall contains an internal rubber strip of relatively high electrical conductivity. Said internal rubber strip extends radially outward from a rubber chafer component of the tire to a tread base layer component of a rubber tire tread of a cap/base configuration, wherein said chafer and tread base rubber compositions are of a relatively high electrical conductivity. The rubber strip thereby provides a path of increased electrical conductivity relative to said outer visible layer of the tire sidewall extending from the tire chafer to the tread base layer tire components.

    摘要： The invention relates to a truck or bus tire with a rubber tread of cap/base construction where the tread cap is composed of an emulsion polymerization prepared styrene/butadiene copolymer elastomer with a relatively random styrene content (E-SBR-A). Such E-SBR-A, in its uncured state, also has a relatively low Tg. In one aspect, the tire tread's tread cap may also be a blend of elastomers such as cis 1,4-polybutadiene and/or natural rubber together with said E-SBR-A and wherein the tread base elastomer is composed primarily of natural cis 1,4-polyisoprene rubber. In another aspect of the invention, said tread cap has a tread design composed of at least three circumferential continuous ribs designed to be road contacting, said ribs independently separated by continuous, circumferential grooves.
