Included are tread bands for use on retreaded tires and methods for retreading a tire using such tread bands. Embodiments of such tread bands include a primary groove having a top opening that is open to a ground contacting front face of the tread band and a secondary groove having a bottom opening that is open to a back face of the tread band. The groove top of the secondary groove is higher than a groove bottom of the primary groove so that the secondary groove top is opened to the ground contacting front face of the tread band prior to disappearance by wear of the primary groove. Particular embodiments may also further include an overflow reservoir having a reservoir opening that is open to the back face of the tread band, the reservoir opening being positioned adjacent to an edge of the secondary groove bottom opening. |
