<p>Particular embodiments of the invention comprise multi-wear layer tire treads for retreaded tires and methods of forming retreaded tires. In particular embodiments, a multi-wear layer tire tread includes a thickness bounded depth wise by a ground-engaging top side and a bottom side, the thickness extending laterally between opposing side edges and longitudinally in a lengthwise direction of the tread. Such tire tread may further include a removable tread portion recessed from the top side to form a subsequent wear layer, the removable tread portion extending into the tread thickness from the bottom side and terminating a distance below the top side, the removable portion having a width arranged between opposing interior surfaces of the tread recessed below the top side.</p> |
