Abstract: The invention includes methods for forming a retreaded tire and treads there for. Particular embodiments of such methods include providing a tire carcass configured to receive a tire tread along an annular tread-receiving area and a pre-formed tread comprising a tread body and a submerged void arranged along a bottom side of the tread and extending into the tread thickness to a top end located below the top side of the tread, the submerged void having a length and an opening arranged along the bottom side when the tread is in an uninstalled configuration, where the opening of the submerged void extends in a direction of the submerged groove length along an alternating, non-linear path. Further steps include assembling a retreaded tire by arranging the tire tread atop a bonding layer arranged between the tire tread and the tire carcass and comprising uncured bonding material.

Abstract: A tread for bonding to a tire carcass to form a retreaded tire having a length, a width, a top side and a bottom side. The tread also includes a central portion and a pair of wing portions extending laterally from the central portions. The top sides of each wing portion include one or more discontinuities having a longitudinal component and configured to resist deflection when subjected to a force from the bottom side and to deflect downwardly when subjected to a force from the top side. In particular embodiments, the one or more discontinuities are arranged within each wing portion are arranged within a thickened portion of each wing portion.

Abstract: A tread support device (10) for a retread process is provided that has a first support roller (12) that rotates about a first support roller axis. A second support roller (16) is present that rotates about a second support roller axis. A third support roller (20) is also included that rotates about a third support roller axis. The first support roller (10), the second support roller (12), and the third support roller (20) all support a tread (24). Also in the tread support device (10), the first support roller axis, the second support roller axis, and the third support roller axis are arranged with respect to one another so as to be located on a circumference of a circle (32).
