RADIAL TIRE SIDEWALL INDENTATIONS
AFFECTED VEHICLES
All Isuzu models equipped with radial tires.
SERVICE INFORMATION
On some affected vehicles, slight indentations may be noticeable on the sidewall surface of one or more tires, giving the sidewall a wavy appearance.
The cause of these indentations lies in a radial tire's construction. In a radial tire, the body ply cords run straight across the tire from bead to bead.
Because of this "straight across" construction, the joining of the ply material in the sidewall area may sometimes cause the sidewall surface to develop
slight indentations when the tire is inflated.
These sidewall indentations are a common characteristic of radial tires and will not affect the tire's performance.
