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.
