Methods for retreading a tire

A method for retreading a tire comprising the steps of:

• providing a tire carcass for retreading, the tire carcass having a pre-existing tread layer extending widthwise across the tire in a lateral direction, the pre-existing tread layer including one or more voids comprising at least one of a groove or sine extending into the tread layer thickness from an outer side of the pre-existing tread layer for engaging a ground surface;
• applying a layer of uncured elastomeric material along an outer side of the pre-existing tread layer, the layer of uncured elastomeric material substantially filling the voids arranged along the outer side of the pre-existing tread layer to provide an outer surface for receiving the pre-cured bonding layer;
• applying a pre-cured tread layer along an outer side of the layer of uncured elastomeric material such that the layer of uncured elastomeric material is arranged between the pre-cured tread layer and the pre-existing tread layer, the pre-cured tread layer having a thickness extending between a front face forming a ground-engaging side of the tread-band pre-cured tread layer and a back face arranged atop the layer of uncured elastomeric material;
• bonding the pre-cured tread layer to the tire carcass to form a retreaded tire having a retreaded tire tread;
• and,
• forming grooves in the retreaded tire tread along a ground-engaging, outer side of the retreaded tire tread.
