    摘要: 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. Formed separately is a wearable filler, the wearable filler having a configuration corresponding to at least a portion of the circumferential or lateral groove formed in the tire. After both the tire and the wearable filler have been cured, the wearable filler 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.
