This invention discloses a tire tread comprising: (a) a first tread cap layer comprising a first rubber composition; and (b) a second tread cap layer arranged radially inside of the first tread cap layer comprising a second rubber composition; wherein at 0&#xb0; C. the rebound resilience of the first rubber composition is within a range of 10% to 25%, the rebound resilience of the second rubber composition is within a range of 15% to 35% and is at least 5% lower than that of the second rubber composition; and wherein at 100&#xb0; C. the rebound resilience of the first rubber composition is within a range of 45% to 65%, the rebound resilience of the second rubber composition is within a range of 60% to 75% and is at least 3% higher than that of the first rubber composition.

Tire having a multilayer tread cap

Tire

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.
