VISUAL GUIDE FOR INSPECTION AND CLASSIFICATION OF TIRES
2-49. TREAD CROWN CONDITIONS (Con't).
i. Proper Timing for Tire Turn-in. Illustrations below are typical examples of what military and
commercial treads will look like when they are worn sufficiently to be turned into maintenance for retread
but before the wear becomes dangerous. Correct classification is CRC F.
2-50. INSIDE TIRE/INNER LINER CONDITIONS.
a. Inner Liner Cracks.
The example to the right shows
two diagonal cracks in an area
other than the inner liner splice
area. This is caused from heat
buildup as a result of
underinflation or a
manufacturing problem. These
cracks are not repairable and the
tire should be classified CRC H.
