Abstract
The invention includes methods of forming a retreaded tire, and treads there for. Particular embodiments of such methods provide a tire carcass configured to receive the tire tread along an annular tread-receiving area and a pre-cured tire tread including a tread body and a detachable connector. The connector is arranged within a thickness of the tread between a top void portion and a bottom void portion and extending across a width of the top void portion and of the bottom void portion. The detachable connector is configured to separate from the tread upon application of a separation force. 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, bonding the tire tread to the tire carcass, and removing the detachable connector from the top void portion after the step of bonding.
