What will cause a tire to fail during an inspection?

A tire will fail during an inspection if there is severe sidewall cracking exposing the chord fabric. This condition indicates significant structural damage and compromises the tire's integrity. The exposed chord fabric is a critical part of the tire's construction, providing strength and stability. When this layer is exposed due to cracking, it can lead to tire failure, such as blowouts, which poses a serious safety risk while driving.

In the context of tire safety standards, sidewall damage is particularly concerning because it can affect the overall performance of the tire, especially during high speeds or under heavy loads. Inspectors are trained to look for any signs of compromised structural integrity, and severe sidewall cracking is a clear indicator that a tire is no longer safe for use.

While tread depth and wear indicators are important factors in assessing tire condition, they do not represent the same immediate danger posed by significant sidewall damage. Normal wear and tear is acceptable to a certain extent if the tire is otherwise sound and meets safety requirements.
