A tire with a changing tread pattern is formed by first forming a tire having a tread, the tread having at least one circumferential or lateral groove. A wearable filler, having a configuration corresponding to at least a portion of the circumferential or lateral groove formed in the tire, is located in the radially outer portion of the circumferential or lateral groove or a portion of the circumferential or lateral groove, and secured within the grooves so as to create a groove void radially inward of the wearable filler, the void being exposed upon wear of the tire tread.
