Abstract
Embodiments include methods for retreading a tire, which include providing a tire carcass for retreading, the tire carcass having a pre-existing tread layer including one or more voids extending into the tread layer thickness from an outer side. A bonding layer is applied along an outer side of the pre-existing tread layer, the bonding layer substantially filling the voids arranged along the outer side of the pre-existing tread layer to provide an outer surface for receiving a pre-cured tread layer. The pre-cured tread layer is applied along an outer side of the bonding layer such that the bonding layer is arranged between the pre-cured tread layer and the pre-existing tread layer. The pre-cured tread layer is bonded to the tire carcass to form a retreaded tire having a retreaded tire tread. Grooves are then formed in the retreaded tire tread along a ground-engaging, outer side of the retreaded tire tread.
