What is the minimum tread depth on tires for a vehicle to be considered safe?

1.0 millimeters
1.6 millimeters
2.0 millimeters
2.5 millimeters

The correct answer is: 1.6 millimeters

For a vehicle to be considered safe, the minimum tread depth on tires is typically set at 1.6 millimeters. This standard is important because adequate tread depth is essential for maintaining traction, especially in wet or slippery conditions. Tires with less than 1.6 millimeters of tread depth can significantly increase the risk of hydroplaning, reduce braking ability, and decrease overall vehicle stability. When vehicles have tires that meet or exceed this minimum tread depth, it ensures that the tires can effectively channel water away from the contact patch, helping to maintain grip and control while driving. Regularly checking tire tread depth and replacing tires when they reach or fall below this minimum threshold is a crucial component of vehicle maintenance and safety.
