VISUAL GUIDE FOR INSPECTION AND CLASSIFICATION OF TIRES
2-47. BEAD AREA CONDITIONS.
a. Burnt Beads. The beads below are examples of burnt beads. This is usually caused from a heat
build up from frequent hard braking or improperly adjusted brakes. The first indications of this type of the
problem are rough, brittle and discolored rubber in the bead area as the first example shows. Advanced
stages will distort the beads and cause the tire to completely fail as shown in the second example. Both
examples are considered unserviceable and non-repairable, CRC-H.
b. Torn Beads. The example below shows a destroyed bead and was caused by removing the tire
from the rim without using a proper demounting tool and tire lubricant. If the bead wire is exposed, rusted,
kinked or broken it cannot be repaired and should be classified CRC H.
c. Cuts or Punctures to close to bead. The injuries shown on the left or right below, can not be
repaired as they run into the non-repairable bead area. Correct classification is CRC H.
