摘要： Particular embodiments include a retreaded tire and a method for retreading a tire. A method may include providing a tire tread having a thickness and a width with grooves extending into the thickness from a tread top side, and providing a tire carcass having an annular tread-receiving side. The method may include applying the tread to the tire carcass with a layer of bonding material arranged between the tread and the tire carcass, and evacuating a gas from between the tire carcass and the tread bottom side through an aperture extending through the tread thickness, the aperture being formed by piercing the tread thickness with a suctioning member arranged in operable communication with a vacuum source, and bonding the tread to the tire carcass. In particular embodiments, portions of the bottom side of the tread beneath the grooves are not bonded to the tire carcass or the bonding layer.

摘要： 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.
