VISUAL GUIDE FOR INSPECTION AND CLASSIFICATION OF TIRES
2-47. BEAD AREA CONDITIONS (Con't).
d. Kinked Bead. Removal of the tire from its rim without proper
lubrication, improper demounting procedures or shipping and handling
damage can bend, kink or distort the beads as shown at the right. The
bead rubber does not have to be torn. Any bends or deformations in the
bead is non-repairable. Correct classification is CRC H.
e. Bead Chafer Separation. As shown below this type of damage is
identified by circumferential cracks just above the bead area with cord
material exposed. This type of damage is usually caused by improper rim
size, overload conditions, underinflation, impacts and sometimes a
manufacturing defect. This damage is non-repairable and the correct
classification for this tire would be CRC H.
f. Bead Area Flow Cracks. Not to be confused with bead chafer separation (above), flow cracks
are distinguished by a circumferential crack that is a cleaner crack with no bead wire exposed as
illustrated below. This is caused by a manufacturing process problem. The tire is non-repairable and
correct classification would be CRC H.
