Patent ID: 8518199

Claim:
A method for manufacturing a retreaded tire comprising: providing a double tread, 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 of the unitary tread body; cutting the double tread along the plane to separate the upper and lower surfaces of the unitary tread body such that a soft, non-oxidized inner rubber layer is exposed along a region defined by the cut along the plane of the double tread, wherein said region defined by the cut is wider than each of the upper and lower surfaces of the unitary tread body; and individually applying one of the upper and lower surfaces to a tire casing within a predetermined time period after the cutting or cementing at least one of the upper and lower surfaces along the region defined by the cut along the plane of the double tread to protect from future oxidation buildup when the applying step occurs outside of the predetermined time period.
