What is the required minimum tread depth for truck tires?

The required minimum tread depth for truck tires is critical for ensuring adequate traction, especially in adverse weather conditions. A minimum tread depth of 1/32 inch (0.8 mm) is established as necessary to maintain a vehicle’s ability to grip the road effectively. When the tread depth becomes shallower than this measurement, the risk of losing traction, particularly in wet or slippery conditions, significantly increases.

Additionally, maintaining tires above this minimum depth helps in managing handling and braking performance, which are crucial for the safety of both the driver and other road users. Furthermore, many jurisdictions have penalties for operating vehicles with tires below the legal tread depth, making awareness of these guidelines essential for drivers and fleet operators.

While other options present greater tread depths, they exceed the minimum requirement and denote a more cautious approach but are not the legally established minimum for truck tires.
