    摘要: The invention relates to a tire having a rubber tread of a circumferentially zoned tread including stratified lateral tread zones and peripheral sidewall extensions. The tread zones are comprised of three circumferential load bearing zones, with each zone containing a portion of the running surface of the tread, comprised of an intermedial zone positioned between and two stratified lateral tread zones together and, in addition, peripheral sidewall extensions. The intermedial and stratified lateral zones are comprised of rubber compositions having differentiated 100° C. hot rebound physical properties. The intermedial rubber zone, or layer, overlays a tread base rubber layer and underlies the lateral tread layer zones. The lateral tread zones are stratified in a sense of being separated from each other and also separated from the from the tread base rubber layer by the intermedial rubber layer. The tread includes a peripheral carbon black rich rubber layer as a sidewall extension which extends radially outward from the outer tire sidewall to thereby join a portion of the peripheral tread zone rubber layer and extends to and includes a portion of the running surface of the tread.

    摘要: The invention relates to a tire having a rubber tread of a circumferentially zoned tread. The tread zones are comprised of three circumferential load bearing zones, with each zone containing a portion of the running surface of the tread, comprised of an intermedial rubber zone positioned between and extending beneath two stratified lateral tread rubber zones. The tread configuration contains an underlying carbon black-rich base rubber layer. The lateral tread rubber zones are therefore spaced apart from each other with the intermedial tread zone therebetween and also spaced apart from the tread base rubber layer with the intermedial tread zone therebetween. The intermedial and stratified lateral zones are comprised of rubber compositions having differentiated rebound physical properties.
