A method for forming a composite tread is described, wherein the method includes the steps of selecting a first tread compound having a first desired tread property, and selecting a second tread compound having a second desired property, forming a tread by winding a dual layer strip having a first layer formed of the first tread compound and a second layer formed of the second compound, wherein the tread has a first and second zone, wherein each zone is formed by spirally winding the dual layer strip, wherein the first zone is formed of a dual layer strip having a strip ratio of the volumetric proportion of the first compound to the second compound used to form the dual layer strip, wherein the second zone has a different strip ratio than the first zone by varying the volumetric proportion of the first compound to the second compound.
