What is the minimum tire tread depth for all wheels with a GVWR of 4499kg or less?

The minimum tire tread depth for all wheels on vehicles with a Gross Vehicle Weight Rating (GVWR) of 4499 kg or less is established at 1.6 mm. This standard is set to ensure adequate traction, handling, and stability under various driving conditions, particularly in wet weather where proper tread depth is crucial for channeling water away and preventing hydroplaning. Tires with worn tread (below this minimum) can significantly decrease a vehicle's grip on the road, increasing the risk of skidding and accidents, especially during emergencies.

In various jurisdictions, tire tread depth regulations are enforced to promote safety on the roads, and 1.6 mm has been widely adopted as a baseline. It's important for truck drivers to regularly inspect their tire conditions to maintain safety standards, ensure compliance with regulations, and avoid penalties. Understanding and adhering to the correct tread depth can not only promote safer driving but also prolong the lifespan of the tires through more even wear patterns.
