Claim:
1. A method for preparing a portion of a tire for repair, the tire having an aperture extending between an interior surface and an exterior surface of the tire, the method comprising the steps of: (a) providing a template having an elongated body, the body having a length at least equal to the length of a tire patch selected for application to the tire adjacent the aperture, a width extending between a pair of opposed guide side edges extending longitudinally along the body, a thickness, and a means for securing the template to the tire; (b) securing the template to an interior surface of the tire by passing the means for securing through the aperture; (c) providing a tool for forming a discontinuity in the interior surface of the tire, wherein the tool is a powered rotary grinding tool and includes a rotary output shaft for transmitting rotational forces and a pair of abrading members operably attached to the output shaft and co-axially aligned; (d) forming with the tool, a discontinuity having a desired discontinuity depth in the interior surface of the tire along each of the opposed guide side edges of the template while the tool is in engagement with the corresponding opposed guide side edge to form a pair of discontinuities spaced apart and at least partially defining the sides of a tire patch application area; and (e) removing the template from the tire.
