The invention relates to a tire with circumferentially zoned tread including 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 rubber zone positioned between and extending beneath two stratified lateral tread rubber zones and, in addition, peripheral sidewall extensions. The tread configuration contains a carbon black reinforced tread base rubber layer underlying the intermedial tread rubber zone. The lateral tread rubber zones are therefore spaced apart from each other with the intermedial tread zone therebetween and also at least partially spaced apart from the tread base rubber layer with the intermedial tread zone therebetween. The tread includes a peripheral carbon black reinforced rubber layer as an extension of the tire sidewall which extends radially outward from the outer tire sidewall to thereby join a portion of a lateral tread zone which may extend to and include a portion of the running surface of the tread.
