Title
(EN) Methods of tire retreading with abutting tread components
Abstract
(EN)

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.
