Methods of tire retreading with abutting tread components

A method of forming a retreaded tire comprising the steps of:

• providing an annular tire carcass configured for receiving a tread;
• providing a plurality of tread components each comprising an independent structure;
• assembling the plurality of tread components to form an assembled tire tread, the tire tread having a thickness extending between a top side configured to engage a ground surface during tire operation and a bottom side configured for attachment to an annular tire carcass configured for receiving the tire tread;
• and,
• bonding the tread 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;
• where the step of assembling a tire tread includes concurrently arranging the plurality of tread components around the outer circumference of the tire carcass to form a tire tread and a bottom side venting void is arranged in fluid communication with a bottom side of a first tread component of the plurality of tread components, the bottom side venting void forming a portion of the tread bottom side and the bottom side venting void extending to a lateral side of the first tread component in fluid communication with the tread top side through a venting passage along one or more sidewalls of the first tread component where the venting passage forms a vertical passage extending in a direction of the tread component thickness and a transverse passage extending in a widthwise direction of the tread component, transverse to the tread component thickness.
