    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 includes methods for forming a retreaded tire. Steps include providing an annular tire carcass and providing a plurality of tread components each comprising an independent structure, which are 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 a bottom side of the tire tread is in removable attachment atop a base retention structure for subsequent application to the tire carcass.

    摘要： Particular embodiments of the present invention include multi-wear layer treads having variable depth grooves for retreaded tires, retreaded tires, and methods of forming retreaded tires. In particular embodiments, such multi-wear layer tire treads include a thickness bounded depthwise by a top side configured to engage a ground surface during tire operation and a bottom side configured for attachment to a tire carcass, the thickness extending laterally between opposing side edges and longitudinally in a lengthwise direction of the tread. Such tread may further include a top groove extending a variable depth into the tread thickness from the top side, the top groove having a groove bottom that varies depthwise within the tread thickness to form multiple wear layers. In other embodiments, top grooves may or may not be variable depth grooves, while the tread further include a bottom groove extending a variable depth into the tread thickness from the bottom side.
