The present invention concerns tire treads having projecting features comprising wear indicators, stone ejectors, and/or noise suppressors arranged within voids submerged below the top, outer side of a tread. Particular embodiments of the invention provide a tire tread having a submerged void extending into to the tread thickness from the bottom side of the tread to a terminal location spaced below the tread top side, the top side forming a ground-engaging side of the tread. Such embodiments further include a plurality of projecting features arranged within the submerged void below the terminal location of the submerged void, the plurality of projecting features being further arranged in a spaced arrangement along a length of the submerged void, each of the plurality of projecting features extending partially across a width of the submerged void, which may comprise a groove, for example. The invention includes methods of forming the tread and a treaded tire.
