Why Tread Depth Matters
Tread depth refers to the thickness of the tire’s tread, which is the rubber compound that comes into contact with the road. The tread depth plays a crucial role in determining a tire’s performance, safety, and lifespan. A tire with insufficient tread depth may not provide adequate traction, leading to reduced braking and handling performance, increased stopping distance, and a higher risk of accidents.
How to Check Tread Depth
Checking tread depth is a simple process that can be done using a penny or a tire tread depth gauge. To check tread depth using a penny, insert the penny into the tire groove with Lincoln’s head facing down. If you can see the top of Lincoln’s head, the tread depth is less than 2/32 of an inch, which is considered worn out. A tire tread depth gauge is a more accurate and convenient way to check tread depth, as it provides a precise measurement of the tread depth in 32nds of an inch.
When to Replace Tires Based on Tread Depth
The American Automobile Association (AAA) recommends replacing tires when the tread depth reaches 1/16 of an inch (1.6 mm). However, some tires may need to be replaced earlier or later depending on their condition, driving habits, and weather conditions. It is essential to consult the vehicle’s owner’s manual or manufacturer’s recommendations for specific guidance on tire replacement based on tread depth.
Additional Factors to Consider
In addition to tread depth, there are other factors to consider when deciding whether to replace tires, including tire age, tire wear patterns, and tire damage. Tires that are more than six years old, even if they have sufficient tread depth, may need to be replaced due to the risk of tire failure. Similarly, tires with uneven wear patterns or damage may need to be replaced earlier than those with normal wear patterns.
By understanding the importance of tread depth and knowing how to check and replace tires based on tread depth, vehicle owners can ensure optimal tire performance, safety, and lifespan. Remember to always consult the vehicle’s owner’s manual or manufacturer’s recommendations for specific guidance on tire replacement based on tread depth.

The American Automobile Association (AAA) recommends replacing tires when the tread depth reaches 1/16 of an inch (1.6 mm) or less, while the National Highway Traffic Safety Administration (NHTSA) recommends replacing tires when the tread depth reaches 2/32 of an inch (1.9 mm) or less.
It’s essential to note that some tires, such as high-performance tires, may have a shorter recommended tread depth. Always check your tire manufacturer’s recommendations for the recommended tread depth for your specific tires.
How to Measure Tread Depth
Measuring tread depth is a simple process that can be done with a tire tread depth gauge or a penny. Here’s how to do it:
- Place the penny in the tire groove with Lincoln’s head facing down.
- If you can see the top of Lincoln’s head, the tread depth is less than 2/32 of an inch (1.9 mm).
- If you can see the top of Lincoln’s ear, the tread depth is between 2/32 and 4/32 of an inch (1.9 mm to 3.2 mm).
- If you can’t see Lincoln’s head or ear, the tread depth is 4/32 of an inch (3.2 mm) or more.
You can also use a tire tread depth gauge, which is a more accurate way to measure tread depth. These gauges are available at most auto parts stores or online.
Consequences of Driving on Worn-Out Tires
Driving on worn-out tires can have serious consequences, including:
- Reduced traction and control, increasing the risk of accidents.
- Poor braking performance, leading to longer stopping distances.
- Increased risk of tire blowouts, especially at high speeds.
