    摘要： The invention relates to a tire of a structural combination of tire tread and sidewall components with compositional limitations containing minimal, if any, of in situ formed alcohol and methyl isobutyl ketone byproducts. The tread component rubber composition contains pre-hydrophobated silica reinforcement. The sidewall component contains low unsaturation EPDM or brominated copolymer of isobutylene and p-methylstyrene and may contain pre-hydrophobated silica reinforcement. The silica reinforcement for said tread and sidewall components is a pre-hydrophobated precipitated silica. The pre-hydrophobated silica is prepared, prior to mixing with the elastomer(s), by reacting hydroxyl groups (e.g. silanol groups) contained on the surface of a precipitated silica with an alkoxyorganomercaptosilane or a combination of an alkoxyorganomercaptosilane and a substituted alkylsilane or with a bis-3(trialkoxysilylalkyl) polysulfide which contains an average of from 2 to 4 connecting sulfur atoms in its polysulfidic bridge to form a composite thereof. The alcohol byproduct therefrom is removed from the composite prior to its introduction into the rubber composition(s). In another aspect of the invention, the connecting sidewall rubber composition, and optionally the tread composition is free of N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine antidegradant (referred herein to as 6PPD) in order to prevent in situ formation of methyl isobutyl ketone byproduct from the reaction of 6PPD with atmospheric oxygen and/or ozone.

    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.
