The correct answer is that the minimum depth of tire tread should be no less than 2/32 of an inch during the inspection. This standard is based on the legal requirements for safe driving. Tread depth is crucial for maintaining traction, especially in wet conditions, as it allows water to escape from beneath the tire, reducing the risk of hydroplaning.

While some may argue for deeper tread depths, the minimum requirement is established to ensure that tires have sufficient grip for safety without being overly restrictive. Having a tread depth of 2/32 of an inch means that a tire is still technically above the legal limit, which can help keep a vehicle compliant with regulations.

Deeper treads, such as 4/32, 6/32, or 8/32 of an inch, while better for traction and performance, exceed the baseline requirement. It is wise for drivers to maintain deeper tread for safety, but the crucial takeaway is that 2/32 of an inch is the minimum acceptable depth to pass an inspection without being considered a safety hazard.
