Abstract
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.
