The legal tire tread depth is a minimum of 2/32 inch (1.6 mm). Drivers must change tires when they reach this depth to ensure vehicle safety and comply with the law. Tires below this level can reduce traction and increase the risk of accidents. Regular checks help maintain safe driving conditions.
To measure tire tread depth, use a tread depth gauge or a simple penny test. Place a penny in the tread groove with Lincoln’s head down. If you can see all of Lincoln’s head, it’s time to replace the tire. Additionally, regularly inspect tires for uneven wear patterns, which may indicate misalignment or inflation issues.
Safety tips include rotating tires every 5,000 to 7,500 miles and checking tire pressure monthly. Maintaining proper tread depth and tire health enhances vehicle safety and performance.
Understanding legal tire tread depth helps ensure compliance and promotes safer driving. Next, we will discuss how tire maintenance, including rotation and inflation, plays a critical role in prolonging tires’ lifespan and performance.
