Damaged reinforcement ending preparation for tire repairs

A method of preparing a portion of a tire for repair, the tire having an exterior side and an interior side, the method comprising the step of:

• forming an opening in the tire extending from the exterior side to the interior side, the opening having a thickness and opposing sides arranged along a perimeter of the opening, each opposing side including an extended portion extending into the opening to define two recessed portions such that each extended portion is arranged between its defined two recessed portions at each opposing side along the perimeter, each extended portion extending into the opening and having the thickness,
• each opposing side having a plurality of tire reinforcement endings arranged along the perimeter of the opening, wherein the extended portions and the recessed portions each include at least one reinforcement ending from the reinforcement endings of their respective opposing sides,
• wherein each extended portion and its defined two recessed portions form an alternating arrangement of reinforcement endings along each opposing side in a direction of the lengths of the tire reinforcements, all of the reinforcement endings being located on the perimeter of the opening at the same distance from the interior side with respect to the thickness direction of the opening.
