Which condition is acceptable for inspected tires to avoid failing?

The condition that inspected tires must show adequate tread with indicators is crucial for ensuring safe vehicle operation. Adequate tread depth is essential for maintaining traction on wet or slippery surfaces, helping to prevent hydroplaning and ensuring effective braking. Tread wear indicators are built into tires to help assess whether the tire has sufficient tread remaining; when these indicators are flush with the surrounding rubber, it indicates that the tire is worn and should be replaced.

Maintaining adequate tread depth is not only a safety concern but also a legal requirement in many jurisdictions, including Texas. Inspectors look for this specific condition because it directly impacts vehicle performance, safety, and adherence to inspection standards. Proper tread thickness enhances the overall functionality of the tires and contributes to the vehicle's stability during operation. In essence, adequate tread with visible indicators is the minimum standard that tires must meet to pass inspection safely.
