What happens if a tire shows tread or sidewall cracks greater than one inch?

When a tire shows tread or sidewall cracks greater than one inch, it will fail inspection due to safety concerns. Significant cracks can compromise the tire's structural integrity and increase the risk of tire failure, which can lead to accidents. Proper tire condition is crucial for safe vehicle operation, as it affects traction, handling, and braking.

While other aspects of the tire, such as tread depth or the possibility of patching, may be considered in different scenarios, the presence of a crack exceeding one inch on either the tread or sidewall is a clear indicator of a defect that poses a risk. Inspections are focused on ensuring that all tire components meet safety standards, and any significant damage, like large cracks, automatically disqualifies the tire from passing inspection.
