2-48. SIDEWALL AREA CONDITIONS (Con't).
d. Diagonal Cracking or Flexbreak Injury. This type of injury, which looks like a series of breaks,
is caused by the excessive flexing and bending of the tire. It is caused by excessive torque transfer,
underinflation and overloading. It cannot be repaired and must be classified CRC H.
e. Tires Run Flat.
(1) The tire below and on the left was run flat for a few miles. If the tire had been run flat much
longer, the whole crown would have been sheared off. The tire damage sill renders it nonrepairable. Note
the signs of shearing on the outside. Correct classification is CRC H.
(2) The tire on the right was also run flat for a few miles. Note the long chain of internal cuts
along the inside of the sidewall. Correct classification is CRC H.
