摘要： The present invention includes methods for forming a retreaded tire, which includes the steps of providing an annular tire carcass and providing a plurality of tread components each comprising an independent structure, which are then assembled to form an assembled tire tread. The tread is subsequently bonded to the tire carcass to form a retreaded tire, the tire tread being arranged along an outer circumference of the annular tire carcass with a bonding layer between the tire tread and the tire carcass, the bonding layer comprising an uncured elastomeric material being cured during the step of bonding. The tire tread is assembled such that the plurality of tread components are concurrently arranged around the outer circumference of the tire carcass to form a tire tread.

摘要： A retread tire and methods for its manufacture, the retread tire having a precured tread band bonded to a prepared bonding surface of a base portion of the tire. The precured tread band includes a back face bonded to the prepared bonding surface of the base portion of the tire and a tread groove bottom portion that extends below the back face of the tread band. The tread groove bottom portion may optionally include a void portion of the tread groove and may include the bottom wall of the tread groove and/or just the side walls of the bottom portion of the tread groove. Also included may be a base groove formed in the base portion of the tire and open to the prepared bonding surface of the tire, wherein the tread groove bottom of the tread groove is embedded within the base groove.

摘要： Embodiments include retreaded tires having a precured tread band bonded to a prepared bonding surface of a base portion of the tire, the tread band including a primary groove having a top open to a ground contacting front face of the tread band and a secondary groove having a bottom open to a back face of the tread band, the back face bonded to the prepared bonding surface, wherein the groove top of the secondary groove is higher than a groove bottom of the primary groove so that the secondary groove top is opened to the ground contacting front face of the tread band prior to disappearance by wear of the primary groove. A base groove may be formed in the base portion of the tire and open to the prepared bonding surface of the tire, wherein the secondary groove bottom opens in fluid communication with the base groove.

摘要： Methods and a tire patch for repairing a damaged tire portion are provided. In one embodiment, such method includes the steps of: buffing an interior surface of the tire about a perimeter of the damaged tire portion to form a patch receiving surface, the interior surface being buffed to a depth sufficient to place a tire patch reinforcement of a tire patch a distance of approximately 3 millimeters or less from a damaged tire reinforcement; covering the damaged portion by applying a pre-assembled patch to the patch receiving surface along the interior surface of the tire, the tire patch sized to cover the damaged area, such patch including a reinforcement layer interposed between an air-impermeable layer and an adhesive layer, the adhesive layer being at least partially uncured for facilitating attachment of the repair patch to the tire; and, curing the patch to the tire.

摘要： Embodiments include a retreaded tire having a precured tread band bonded to a prepared bonding surface of a base portion of the tire. The precured tread band may include a tread groove having a bottom and a top, the top of the groove open to a ground contacting front face of the tread band, the precured tread band further comprising a back face, the back face bonded to a prepared bonding surface of a base portion of the tire. A base groove may be formed in the base portion of the tire and open to the prepared bonding surface of the tire, wherein the tread groove bottom is aligned over a length of the base groove. In some embodiments, the tread groove bottom may be open to the base groove over at least 50% or the entire length of the base groove.
