You can quickly and easily check the tread depth of your tires using a penny and/or a quarter.
- Purpose: The penny test helps determine if your tire tread has worn down to the legally recommended minimum of 2/32nds of an inch.
- How to do it:
– Find a penny and place it, Lincoln’s head facing downwards, into a tire tread groove.
– Observe if the top of Lincoln’s head is visible.
- Interpretation:
– If you can’t see the top of Lincoln’s head, your tread depth is likely above 2/32nds of an inch, and your tires may be okay for continued use.
– If you can see the top of Lincoln’s head, it suggests your tread depth is at or below the minimum legal limit of 2/32nds of an inch, and replacing the tire is recommended.
- Purpose: This test helps identify if your tires have worn to or below 4/32nds of an inch, a depth at which safety and performance, especially in wet conditions, can be diminished. Some experts recommend replacing tires when they reach this depth.
- How to do it:
– Place a quarter, Washington’s head facing downwards, into a tire tread groove.
- Interpretation:
– If you can’t see the top of Washington’s head, your tread depth is likely above 4/32nds of an inch.
– If you can see the top of Washington’s head, it means your tread depth has fallen to or below 4/32nds of an inch. At this point, consider replacing your tires soon.
Important Notes:
- Check multiple spots: Always check the tread depth in several places across each tire, and pay close attention to the areas that appear most worn.
- Uneven wear: Uneven wear might indicate problems with tire inflation, wheel alignment, or other issues, and a technician should inspect your vehicle.
- Safety recommendations: While 2/32nds of an inch is often the legal minimum, it’s wise to consider replacing tires around 4/32nds of an inch or earlier, especially if you frequently drive in wet or snowy conditions.
- Alternatives: A tire tread depth gauge provides a more precise measurement than the coin tests and is readily available at auto parts stores.
- Professional inspection: If you’re unsure about your tire’s condition or have any concerns, it’s always best to consult with a qualified mechanic or tire specialist.
