What is the minimum tread depth required for front tires?

The minimum tread depth required for front tires is 4/32 of an inch. Maintaining adequate tread depth is crucial for safety, as it directly affects traction, handling, and stopping distance. Insufficient tread depth can lead to hydroplaning in wet conditions and reduced grip on surfaces, particularly during emergency maneuvers. In many jurisdictions, regulations establish this minimum to help ensure that vehicles have the necessary performance capabilities to operate safely on the road.

The other options represent tread depths that fall below this safety standard, which could compromise the vehicle's performance and increase the risk of accidents. Ensuring that the front tires have at least 4/32 of an inch of tread is essential for both driver safety and regulatory compliance.
