VISUAL GUIDE FOR INSPECTION AND CLASSIFICATION OF TIRES
(Con't)
2-48. SIDEWALL AREA CONDITIONS (Con't).
f. Tires Sitting Flat. This tire on the right went flat
while the vehicle was parked and remained flat for some
time. Unlike the damage done when tires are run flat, the
sidewall was not sheared, but it has been bent out of shape
and many cords could be broken or permanently deformed.
The tire is nonrepairable. Correct classification is CRC H.
g. Sidewall Separation.
The illustrations below show two different stages of
sidewall separations. Separations usually begin with an irregular shaped bulge in the mid to upper sidewall
as shown in the first example, or breaks in the sidewall as shown in the second example. Eventually the
damage may progress to complete separation of the sidewall rubber. This type of damage is caused by
lack of adhesion between the sidewall rubber and body ply. Punctures, severe impacts, damage to the
inner liner, bead damage or a manufacturers defect may cause separations. Sidewall bulges should not be
confused with the normal sidewall waviness that some radial tires have. Any separation should be reason
to scrap the tire and the correct classification would be CRC H.
