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： The present invention includes an improved tire tread having recessed lateral grooves, and a tire having the same. Particular embodiments of the tread include a tread thickness bounded depthwise by a top side configured to engage a ground surface during tire operation and a bottom side configured to attach to a tire carcass, the thickness extending laterally between a first side edge and a second side edge and longitudinally in a lengthwise direction of the tread. The tread further includes a longitudinal groove in fluid communication with the top side or the bottom side of the tread thickness and a lateral groove in fluid communication with the bottom side of the tread thickness extending from the first side edge intersecting the longitudinal groove forming a vent passageway extending from the longitudinal groove and to the first side edge. The invention includes methods of forming such treads and molds there for.

摘要： Embodiments of the invention include methods and apparatus for constraining a tread in a desired arrangement about a tire carcass during retreading operations. Such methods include the steps of providing a annular tire carcass configured for receiving a tread. Such methods also include the step of arranging a tread annularly about the precured tire carcass in a desired position to form an assembled retreaded tire. Such methods further include the step of arranging a retread curing membrane about an outer side of the tread, the curing membrane including an interior surface arranged to engage the outer side of the tread and including one or more protrusions extending from the membrane interior surface and into a void of the outer side of the tread. In other embodiments, a separate insert containing protrusions is arranged between a curing membrane and a tire tread for retread curing operations.

摘要： The present invention comprises methods and apparatus for preparing a tread for application to a tire carcass by abrading a bottom side of the tread. In particular, the tread has a thickness extending depthwise between a top side and a bottom side of the tread. The tread thickness extends in a longitudinal direction and in a lateral direction between opposing sides of the tread. The tread further includes a void extending within the tread thickness and an extension of the tread extending across a width of the void and as a portion protruding outwardly from the tread bottom side by a distance. Such methods include stretching the tread such that the width of the tread void increases and the distance by which the extension protrudes from the bottom side decreases. Such methods further include abrading the bottom side of the tread.
