Methods and a tire patch for repairing a damaged tire portion are provided. In one embodiment, such method includes the steps of: buffing an interior surface of the tire about a perimeter of the damaged tire portion to form a patch receiving surface, the interior surface being buffed to a depth sufficient to place a tire patch reinforcement of a tire patch a distance of approximately 3 millimeters or less from a damaged tire reinforcement; covering the damaged portion by applying a pre-assembled patch to the patch receiving surface along the interior surface of the tire, the tire patch sized to cover the damaged area, such patch including a reinforcement layer interposed between an air-impermeable layer and an adhesive layer, the adhesive layer being at least partially uncured for facilitating attachment of the repair patch to the tire; and, curing the patch to the tire.
