Pneumatic tire

A pneumatic tire having a tread comprising

• a tread base layer;
• a tread cap comprising a first tread cap layer and a second tread cap layer formed of different polymeric compositions,
• the tread having a central zone ZC and two lateral zones ZL the lateral zones ZL being located axially adjacent to the central zone ZC and on axially opposite sides of the central zone ZC,
• wherein the first tread cap layer is arranged radially outward of the tread base layer and axially extends through the central zone ZC and both lateral zones ZL,
• wherein the second tread cap layer is arranged within the central zone ZC and radially outside of both the tread base layer and at least part of the first tread cap layer, wherein the second tread cap layer is not located within both lateral zones,
• wherein the tread further comprises a first rib located between a second rib and third rib, and wherein a first groove is located between the first and second rib and a second groove is located between the first and third rib, wherein each rib is formed of the first tread cap layer and the second tread cap layer,
• and wherein the second tread cap layer has a first portion in the first rib that extends radially inward of the first and second grooves, and wherein the second tread cap layer has a second portion in the second rib that extends radially inward of the first and second grooves, and the second tread cap layer has a third portion in the third rib that extends radially inward of the first and second grooves, wherein the first portion extends radially inward of the second portion and the third portion.
