Abstract: A method of treading or re-treading tires involves compression of the wearing surface of the tread. A tread strip, which may be an annular band, is compressed in a direction parallel to its longitudinal axis and is bonded to a tire carcass, while being maintained under compression. This may be done by compressing a tread band into an undersized mould; apparatus for assisting this is also described. Alternatively, the tread strip may be of finite length, for example to form a lug, in which case the strip is formed with a radius of curvature less that of the surface to which it is to be applied, so that the convex (wearing) surface of the strip is compressed upon application to the carcass.

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.
