What is the minimum tread depth for tires to pass inspection?

The minimum tread depth for tires to pass inspection is 2/32 inch. This standard is set to ensure sufficient traction for safe vehicle operation, particularly in wet or slippery conditions. Tread depth is critical for preventing hydroplaning, enhancing braking efficiency, and providing overall vehicle stability. A minimum depth of 2/32 inch helps ensures that the tires can effectively channel water away and maintain contact with the road, reducing the risk of accidents caused by tire failure or lack of grip. As the tread wears down below this threshold, the tires' ability to perform safely diminishes significantly, making regular inspections and adherence to these standards crucial for both driver safety and public road safety.
