Abstract: A heavy truck tire is provided that has a plurality of tread zones located at different locations in a lateral direction of the tread and configured for engaging a road. The first tread zone has a first max tan(?), and a second tread zone located next to the first tread zone in the lateral direction has a second max tan(?) is different than the first max tan(?). The second tread zone is between the first tread zone and a third tread zone. The third tread zone has a third max tan(?) that is the same as or close to the first max tan(?). The first, second and third max tan(?) are all within the range from 0.01-0.30. Also, either the first max tan(?) is at least 0.05 greater than the second max tan(?) or the second max tan(?) is at least 0.05 greater than the first max tan(?).

Abstract: 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(?) than a max tan(?) of the second layer. The max tan(?) of the first layer is from 0.06-0.15, and the max tan(?) of the second layer is from 0.12-0.27. The tire also has a sculptural feature that reduces irregular wear.

Abstract: The invention provides for a heavy truck tire having a sub-casing, a belt package and a rubber tread, the tread comprising a center zone separating two shoulder zones. The upper shoulder layer consisting of an upper shoulder rubber compound being different from a lower shoulder rubber compound, wherein: the upper shoulder rubber compound has a G*50 of at least 1.3 Mpa and a max tan(?) of at least 0.12; the lower shoulder rubber compound has a max tan(?) not greater than the max tan(?) of a center rubber compound in the center zone being intended to come into contact with the ground; and the center rubber compound has a max tan(?) of at most 0.09.
