Tire safety is a crucial aspect of vehicle maintenance, and one of the most important aspects of tire safety is the tread depth. A tire with worn-out tread can lead to reduced traction, increased stopping distance, and even accidents. This is where the penny test comes in – a simple and effective way to check the tread depth of your tires. In this article, we will explore how to test tire tread with a penny and why it’s an essential part of your vehicle’s maintenance routine.
The Importance of Tire Tread Depth
Tire tread depth is the measure of how much tread is left on the tire. The tread depth is measured in 32nds of an inch, and it’s an important indicator of a tire’s overall condition. A tire with a tread depth of 10/32″ or less is considered worn out and should be replaced. Worn-out tires can lead to a range of problems, including reduced traction, increased stopping distance, and even accidents.
When a tire is worn out, the tread is no longer able to provide the necessary grip and traction on the road. This can lead to a range of problems, including:
- Reduced traction: A worn-out tire can struggle to grip the road, leading to reduced traction and increased stopping distance.
- Increased stopping distance: A tire with worn-out tread can take longer to stop, which can be a major safety concern.
- Increased risk of accidents: A worn-out tire can increase the risk of accidents, particularly in wet or slippery conditions.
- Reduced tire life: Worn-out tires can lead to reduced tire life, as the tire is no longer able to provide the necessary support and traction.
The Penny Test: How to Check Tire Tread Depth
The penny test is a simple and effective way to check the tread depth of your tires. To perform the test, you’ll need a penny and a tire. Here’s how it works:
Insert the penny into the tire groove with Lincoln’s head facing down. If you can see the top of Lincoln’s head, your tire tread is worn out and should be replaced. If you can’t see the top of Lincoln’s head, your tire tread is still within the recommended depth. (See Also: Which Number Is Tire Height? Decoding The Correct Measurement)
How to Perform the Penny Test
To perform the penny test, follow these steps:
- Find a tire groove: Look for a tire groove that is deep enough to accommodate the penny. The tire groove should be free of any debris or obstructions.
- Insert the penny: Insert the penny into the tire groove with Lincoln’s head facing down. Make sure the penny is inserted at a 45-degree angle.
- Check the tread depth: Check the tread depth by looking for the top of Lincoln’s head. If you can see the top of Lincoln’s head, your tire tread is worn out and should be replaced. If you can’t see the top of Lincoln’s head, your tire tread is still within the recommended depth.
- Repeat the test: Repeat the test for all four tires to ensure that they are all within the recommended tread depth.
Tire Tread Depth Standards
Tire tread depth standards vary depending on the country and region. In the United States, the National Highway Traffic Safety Administration (NHTSA) recommends that tires have a tread depth of at least 10/32″ to ensure safe driving conditions. In Canada, the Canadian Tire and Rubber Association (CTRA) recommends a tread depth of at least 10/32″ for passenger vehicles and 12/32″ for commercial vehicles.
Tire Tread Depth Standards by Country
| Country | Tire Tread Depth Standard |
|---|---|
| United States | 10/32″ |
| Canada | 10/32″ (passenger vehicles), 12/32″ (commercial vehicles) |
| European Union | 1.6 mm (approximately 12/32″) |
Conclusion
Checking tire tread depth is an essential part of vehicle maintenance. The penny test is a simple and effective way to check the tread depth of your tires. By following the steps outlined in this article, you can ensure that your tires are within the recommended tread depth and safe for driving. Remember to check your tires regularly to ensure that they are in good condition and to prevent accidents.

Frequently Asked Questions
Q: How often should I check my tire tread depth?
A: It’s recommended to check your tire tread depth every 12,000 to 15,000 miles or every 6 months, whichever comes first.
Q: Can I use a different object to check my tire tread depth?
A: Yes, you can use a tire tread depth gauge or a tire tread depth sticker to check your tire tread depth. However, the penny test is a simple and effective way to check your tire tread depth.
Q: What happens if I don’t check my tire tread depth?
A: If you don’t check your tire tread depth, you may not notice when your tires are worn out. This can lead to reduced traction, increased stopping distance, and even accidents.
Q: Can I drive on worn-out tires?
A: No, it’s not recommended to drive on worn-out tires. Worn-out tires can lead to reduced traction, increased stopping distance, and even accidents. It’s best to replace worn-out tires with new ones to ensure safe driving conditions. (See Also: How Much Does a Tire Sensor Cost to Replace? Unveiled)
Q: How do I know if my tires are worn out?
A: You can check your tire tread depth using the penny test or a tire tread depth gauge. If your tire tread depth is 10/32″ or less, your tires are considered worn out and should be replaced.
