Patent ID: 8662126

Claim:
A double tread for tire retreading, the double tread comprising: a first design side comprising an upper surface having a first tread pattern molded in a unitary tread body; and a second design side comprising a 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; wherein the unitary tread body has a width along the plane that is larger than a width along each of the upper and lower surfaces; wherein the double tread is separable into a first tread and a second tread along the plane to provide the first and second tread patterns, wherein the entire cut surface of the first and second treads is defined only by rubber, and wherein each of the first and second treads presents a soft, non-oxidized inner rubber layer adapted for being individually applied to a respective tire casing after the unitary tread body has been separated along the plane to produce first and second treads, or is cemented along a region defined by the cut along the plane of the double tread to protect from future oxidation buildup when application to the respective tire casing occurs outside of a predetermined time period.
