Zusammenfassung:	A heavy truck tire is provided that includes a casing with a central axis, and a rubber tread that has a first layer and a second layer. The first layer is located farther from the central axis in a radial direction than the second layer. The first layer has a lower max tan(δ) than a max tan(δ) of the second layer. The max tan(δ) of the first layer is from 0.06-0.15, and the max tan(δ) of the second layer is from 0.12-0.27. The tire also has a sculptural feature that reduces irregular wear.
