Tire safety is a critical aspect of vehicle maintenance, and one of the most important factors to consider is the tread depth of your tires. A tire with worn-out tread can lead to reduced traction, increased stopping distance, and even accidents. However, checking the tread depth of your tires can be a daunting task, especially for those who are not familiar with the process. In this article, we will discuss how to check tire tread with a coin, a simple and effective method that can help you determine if your tires need to be replaced.
Why is Tire Tread Important?
Tire tread is the rubber portion of the tire that comes into contact with the road. It plays a crucial role in providing traction, handling, and braking performance. A tire with good tread depth can grip the road better, reduce the risk of skidding, and improve overall safety. On the other hand, a tire with worn-out tread can lead to reduced traction, increased stopping distance, and even accidents.
The American Automobile Association (AAA) recommends checking tire tread depth at least once a month. This can be done using a simple method called the “penny test” or the “coin test.” This method involves inserting a coin into the tire tread and checking the depth of the tread. If the tread is worn out, it can lead to reduced traction and increased stopping distance.
The Coin Test: How to Check Tire Tread with a Coin
The coin test is a simple and effective method to check tire tread depth. Here’s how to do it:
Step 1: Choose the Right Coin
Choose a coin that is at least 11.5 cm (4.5 inches) in diameter. The most commonly used coin for this test is the Lincoln penny. The penny has a diameter of 19.05 mm (0.75 inches), which is ideal for this test.
Step 2: Insert the Coin
Insert the coin into the tire tread groove with the Lincoln Memorial side facing down. Make sure the coin is inserted at a 90-degree angle to the tire tread.
Step 3: Check the Depth
Check the depth of the tread by looking at the coin. If the tread is worn out, the coin will be visible in the groove. If the tread is still good, the coin will not be visible. (See Also: Can Tubeless Tires Go Flat? The Surprising Truth)
What to Look for
When checking the tread depth, look for the following:
- If the tread is worn out, the coin will be visible in the groove.
- If the tread is still good, the coin will not be visible.
- If the tread is between 1/16 inch and 1/8 inch deep, the coin will be partially visible.
What is the Minimum Tread Depth?
The minimum tread depth recommended by the National Highway Traffic Safety Administration (NHTSA) is 1/16 inch (1.6 mm). If the tread depth is less than this, it is recommended to replace the tire.
Other Methods to Check Tire Tread Depth
While the coin test is a simple and effective method to check tire tread depth, there are other methods available. Some of these methods include:
Using a Tire Tread Depth Gauge
A tire tread depth gauge is a small device that can be purchased at most auto parts stores. It consists of a long, thin probe that is inserted into the tire tread groove to measure the depth of the tread.
Using a Tread Depth App
There are several tread depth apps available for smartphones that can help you check tire tread depth. These apps use the camera on your phone to measure the tread depth.
Benefits of Regular Tire Tread Checks
Regular tire tread checks can provide several benefits, including:
Improved Safety
Regular tire tread checks can help you identify worn-out tires and replace them before they lead to accidents. (See Also: Does Bj’s Fix Flat Tires? The Ultimate Answer)

Q: Can I use any coin to check tire tread depth?
A: No, it is recommended to use a coin that is at least 11.5 cm (4.5 inches) in diameter. The most commonly used coin for this test is the Lincoln penny.
Q: What if my tire tread depth is between 1/16 inch and 1/8 inch deep?
A: If your tire tread depth is between 1/16 inch and 1/8 inch deep, it is recommended to replace the tire. This is because the tread is still good, but it may not provide optimal traction and handling.
