What is one inspection criterion for tires?

Adequate tread is a crucial inspection criterion for tires because it directly impacts the vehicle's traction, stability, and handling on the road. Tread depth helps determine how well a tire can grip the surface, especially in wet or slippery conditions. Insufficient tread can lead to hydroplaning, reduced braking effectiveness, and overall increased risk of accidents.

Maintaining an adequate tread depth is essential not only for safety but also for compliance with regulations pertaining to vehicle maintenance. Inspectors usually use tools or gauge measurements to assess tread depth and ensure it meets the minimum requirements set by industry standards.

Other criteria, such as color brightness, proper branding, and tire age, while still important for different aspects of tire condition, do not have as direct an effect on the performance and safety of the tire in the same way that tread depth does.
