Abstract: A tread for a pneumatic tire in accordance with the present invention includes a tread base layer, a first tread cap layer radially outside of the tread base layer, a second tread cap layer radially outside of the tread base layer and both radially outside and axially adjacent the first tread cap layer, a third intermediate layer radially between the tread base layer and the first and second tread cap layers. The first tread cap layer has a protrusion extending radially inward and into the third intermediate layer more than a main body of the first tread cap layer and the second tread cap layer thereby allowing the first tread cap layer to provide the overall tread with enhanced performance characteristics after the main body of the first tread cap layer and the second tread cap layer have worn away.

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.
