What is the minimum tread depth allowed on steering tires?

The minimum tread depth required on steering tires is crucial for maintaining vehicle control, especially in wet conditions. This depth ensures that tires can adequately grip the road surface, reducing the risk of hydroplaning and enhancing overall handling. A tread depth of 4/32 of an inch is the minimum standard for steering tires, as it allows for better water displacement and improves traction. Ensuring that steering tires meet this minimum depth is vital for safety, particularly for heavy vehicles that place more stress on tires. Maintaining adequate tread depth helps to prevent tire blowouts and assists in effective braking, steering, and overall vehicle stability.
