Particular embodiments of such methods provide a tire tread, the tire tread having a bottom side and a top side configured for engaging a ground surface, a thickness extending between the top side and the bottom side, and a pair of opposing lateral sides defining a width of the tread, the bottom side having one or more submerged voids extending from the bottom side into the tread thickness to form a tread pattern, the submerged voids having a depth less than the thickness and the top side being free of any exposed voids comprising a groove. Further steps include applying the tire tread to a tire carcass, curing the tire tread to the tire carcass, and forming one or more voids into the tread thickness the top side of the tread after the step of bonding.
