What is the required tread depth in major grooves for dual treads?

The correct answer indicates that the required tread depth in major grooves for dual treads is at least 2/32 inch. This measurement is crucial for ensuring the safety and performance of the vehicle. Adequate tread depth is essential for maintaining traction, especially in wet or slippery conditions, as it allows the tire to channel water away and reduce the risk of hydroplaning.

When treads wear down below this minimum threshold, the ability of the tire to grip the road effectively diminishes, increasing the risk of accidents. Regulation standards set these minimum tread depth requirements to promote safer driving conditions for all road users. Maintaining proper tread depth is a key component of vehicle maintenance, ensuring optimal handling and safety performance.
