A tread for a heavy truck tire, comprising: a plurality of tread zones (18, 20, 22, 92, 94, 96, 98) that are located at different locations in a lateral direction of the tread, wherein a first tread zone of the plurality of tread zones (18, 20, 22, 92, 94, 96, 98) has a first max tan(δ), wherein the first tread zone is configured for engaging a road; a second tread zone of the plurality of tread zones (18, 20, 22, 92, 94, 96, 98) has a second max tan(δ), wherein the second tread zone is configured for engaging the road; a third tread zone of the plurality of tread zones (18, 20, 22, 92, 94, 96, 98) has a third max tan(δ)wherein the third tread zone is configured for engaging the road; characterized in that the second tread zone is located next to the first tread zone in the lateral direction, wherein the second tread zone has a second max tao(δ) that is different from the first max tan(δ), said third tread zone is located next to the second tread zone in the lateral direction such that the second tread zone is located between the first and third tread zones (18, 22) in the lateral direction, the first max tan(δ), the second max tan(δ), and the third max tan(δ) are all within the range from 0.01 - 0.30; either [the third max tan(δ) is the same as the first max tan(δ)] or [the third max tan(δ) and first max tan(δ) are different but not more than 0.05 different from one another]; either [the first max tan(δ) is at least 0.05 greater than the second max tan(δ)] or [the second max tan(δ) is at least 0.05 greater than the first max tan(δ)); if the first max tan (δ) is greater than the second max tan (δ) then the third max tan(δ) is greater than the second max tan(δ), and if the first max tan(δ) is less than the second max tan(δ) then the third max tan(δ) is less than the second max tan(δ) the loss factor tan(δ) is measured according to standard ASTM D5992-96 at a frequency of 10 Hz and at a temperature of 60 °C. a plurality of tread zones (18, 20, 22, 92, 94, 96, 98) that are located at different locations in a lateral direction of the tread, wherein a first tread zone of the plurality of tread zones (18, 20, 22, 92, 94, 96, 98) has a first max tan(δ), wherein the first tread zone is configured for engaging a road; a second tread zone of the plurality of tread zones (18, 20, 22, 92, 94, 96, 98) has a second max tan(δ), wherein the second tread zone is configured for engaging the road; a third tread zone of the plurality of tread zones (18, 20, 22, 92, 94, 96, 98) has a third max tan(δ)wherein the third tread zone is configured for engaging the road; the second tread zone is located next to the first tread zone in the lateral direction, wherein the second tread zone has a second max tao(δ) that is different from the first max tan(δ), said third tread zone is located next to the second tread zone in the lateral direction such that the second tread zone is located between the first and third tread zones (18, 22) in the lateral direction, the first max tan(δ), the second max tan(δ), and the third max tan(δ) are all within the range from 0.01 - 0.30; either [the third max tan(δ) is the same as the first max tan(δ)] or [the third max tan(δ) and first max tan(δ) are different but not more than 0.05 different from one another]; either [the first max tan(δ) is at least 0.05 greater than the second max tan(δ)] or [the second max tan(δ) is at least 0.05 greater than the first max tan(δ)); if the first max tan (δ) is greater than the second max tan (δ) then the third max tan(δ) is greater than the second max tan(δ), and if the first max tan(δ) is less than the second max tan(δ) then the third max tan(δ) is less than the second max tan(δ) the loss factor tan(δ) is measured according to standard ASTM D5992-96 at a frequency of 10 Hz and at a temperature of 60 °C.
