What is the minimum tread depth required for tires other than front steer tires?

The minimum tread depth required for tires other than front steer tires is 2/32 of an inch. This measurement is critical for maintaining safe driving conditions, particularly for ensuring proper traction and hydrodynamic performance in wet conditions. A tread depth of 2/32 of an inch is the legal minimum allowed, and tires worn down to this level can significantly reduce a vehicle’s grip on the road, especially during braking or cornering.

Tires that have tread depths lower than this can lead to increased risk of hydroplaning and reduced overall traction, which can be particularly dangerous under adverse weather conditions. Therefore, maintaining at least 2/32 of an inch not only meets legal requirements but also promotes safety on the road.
