Claim:
A double tread mold for forming a double tread for tire retreading, the double tread mold comprising: an upper mold portion for forming an upper surface of the double tread; and a lower mold portion for forming a lower surface of the double tread, the double tread comprising (a) a first design side comprising the upper surface having a first tread pattern molded in a unitary tread body, and (b) a second design side comprising the lower surface having a second tread pattern molded in the unitary tread body, the second tread pattern opposingly oriented with respect to the first tread pattern across a plane between and parallel to the upper and lower surfaces, the first and second tread patterns adapted for being individually applied to a tire casing; wherein the upper and lower mold portions close along an interface to form an internal cavity in which the double tread is formed, the interface including an inner-most region that is associated with the plane between and parallel to the upper and lower surfaces, the inner-most region being disposed between the upper and lower surfaces such that the first design side is formed by the upper mold portion and the second design side is formed by the lower mold portion.
