Abstract:
A pneumatic tire having a tire tread is disclosed, wherein the tread comprises one or more tread elements and one or more grooves, the tread having a radially outer surface and a non-skid tread depth as measured from the radially outer surface of the tread and a radially innermost surface of the grooves. The tread has a radially innermost layer comprised of a base tread compound, a radially outer tread cap layer and a middle tread caplayer located between the base layer and the outer tread cap layer. Wherein the radially outer tread cap layer has a defined depth D, except that there is at least one notched areas wherein the tread cap layer extends radially inward of the defined depth D.
