TM 9-2610-200-14 2-82 CHAPTER 2. CARE, MAINTENANCE, AND INSPECTION (Con't)SECTION V. GENERAL SUPPORT MAINTENANCE (Con't) 2-39. TIRE REPAIR AND REPAIR LIMITS (Con't). d. Repair Area Measurements. (1) Once the injury has been skived out, a measurement must be taken to ensure that the area to be repaired falls within repairable parameters. In bias ply tires, the longest measurement of cord damage, in anyone direction is used (see bias illustration to the right). In radial tires, the size of a sidewall injury is measured within a rectangle; the length of the damage is along the cords and the width of the damage is across the cords. The widest points in both length and width are used. The size of a crown injury is determined by the maximum diameter of the damage (see radial illustration below and to the right).(2) To determine if an injury is repairable check the size and section width of the tire against the tables on the following pages. Section width is the width of the tire from sidewall to sidewall, with the tire mounted and inflated but not loaded (see illustration below). Section width is usually indicated in the first set of numbers of the tire size imprinted on the sidewall. For example, for a tire size of 11.00R22.5 the section width would be 11 inches.
