Condition / Concern
Slight sidewall indentations are a common characteristic of radial tire construction. These indentations are more noticeable on larger size tires having a larger side wall height. Radial tire body construction includes individual cords that run parallel to each other from bead to bead (down the sidewall, across the tread and up the other sidewall). These cords will overlap at points on the circumference of the tire. When the tire is mounted and inflated, it is free to naturally expand. The overlapped areas may create slight indentations, undulations, or protrusions since the stretching capacity of the overlapped area is slightly different than the rest of tire sidewall area.

Condition / Concern
Slight sidewall indentations are a common characteristic of radial tire construction. These
indentations are more noticeable on larger size tires having a larger side wall height. Radial tire
body construction includes individual cords that run parallel to each other from bead to bead (down
the sidewall, across the tread and up the other sidewall). These cords will overlap at points on
the circumference of the tire. When the tire is mounted and inflated, it is free to naturally
expand. The overlapped areas may create slight indentations, undulations, or protrusions since the
stretching capacity of the overlapped area is slightly different than the rest of tire sidewall
area.
The following two photo’s show examples of tires with a sidewall indentation.
Recommendations / Instructions
This is a visual condition that will not affect durability, reliability or performance of the tires.
Tire replacement to address this condition is not recommended and will lead to customer
dissatisfaction as the replacement tires will likely have the same or similar condition.
Note: Indentations are not to be confused with sidewall bulges. An “outward” sidewall bulge
indicates a spread or broken cord(s). Tires with an “outward” sidewall bulge should be replaced.
Customer Information
Please communicate to the customer that slight sidewall indentations are a common characteristic of
radial tire construction and will not impact the designed performance or reliability of the
vehicle. Please share this information with the customer, including a copy of this message.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition
exhibited is resolved without completing every step, the remaining steps do not need to be
performed.
