Maintaining proper tire tread depth is crucial for safe and efficient driving. Worn tires can significantly reduce traction, increase braking distances, and compromise your vehicle’s handling, especially in wet or icy conditions. Luckily, there’s a simple and readily available tool you can use to check your tire tread depth: a penny.
How to Check Tires with a Penny
This method, recommended by many tire safety experts, allows you to quickly and easily assess whether your tires need replacing.
What You’ll Need
- A penny
- A well-lit area
By following these steps, you can ensure your tires are in good condition and contribute to a safer driving experience.
How To Check Tires With A Penny
Maintaining properly inflated tires is crucial for safe and efficient driving. Underinflated tires can lead to decreased fuel economy, increased wear and tear, and a higher risk of blowouts. Overinflated tires, on the other hand, can result in a harsher ride, reduced traction, and uneven tire wear. Thankfully, checking your tire pressure is a simple task that can be done at home using a common household item: a penny.
Understanding Tire Pressure
Tire pressure is measured in pounds per square inch (PSI). Each vehicle has a recommended PSI range, which is typically found in the owner’s manual, on a sticker inside the driver’s side doorjamb, or on the tire sidewall. It’s important to check your tire pressure regularly, as it can fluctuate due to temperature changes, driving conditions, and even time.
The Penny Test: A Quick and Easy Method
The penny test is a quick and easy way to get a general idea of your tire pressure. While it’s not as accurate as using a tire pressure gauge, it can be a helpful tool for identifying tires that are significantly underinflated.
How to Perform the Penny Test
1.
Take a standard US penny and insert it into the tread groove of your tire, with Lincoln’s head facing downwards.
2.
If you can see the top of Lincoln’s head, your tire is underinflated.
3.
If you can only see the top of Lincoln’s hair, your tire pressure is likely within the acceptable range.

If the entire penny is covered by the tread, your tire is likely overinflated.
Interpreting the Results
The penny test provides a visual indication of your tire pressure. However, it’s important to remember that it’s not a precise measurement. If you find that your tires are underinflated, you should use a tire pressure gauge to check the PSI and inflate them to the recommended level.
Important Considerations
*
The penny test is most accurate when performed on tires that are cold. Avoid checking tire pressure after driving, as the heat generated by the tires will cause the pressure to increase.
*
The penny test is not a substitute for a tire pressure gauge. For accurate readings, always use a gauge.
*
Pay attention to the recommended PSI range for your vehicle. Different vehicles have different tire pressure requirements.
Maintaining Proper Tire Pressure
Regularly checking and maintaining your tire pressure is essential for safe and efficient driving. Here are some tips for keeping your tires properly inflated:
Tips for Maintaining Tire Pressure
*
Check your tire pressure at least once a month, or more frequently if you drive in extreme temperatures or conditions.
*
Use a reliable tire pressure gauge to ensure accurate readings. (See Also: What Psi Should Bicycle Tires Be)
*
Inflate your tires to the recommended PSI range, as specified in your owner’s manual or on the tire sidewall.
*
Store your spare tire properly inflated.
*
Be aware of changes in tire pressure due to temperature fluctuations. As temperatures drop, tire pressure decreases, and vice versa.
Benefits of Proper Tire Inflation
Maintaining proper tire pressure offers numerous benefits, including:
Benefits of Proper Tire Inflation
*
Improved Fuel Economy: Underinflated tires create more rolling resistance, which can decrease fuel efficiency. Properly inflated tires reduce this resistance, saving you money at the pump.
*
Enhanced Handling and Safety: Proper tire pressure improves handling, steering responsiveness, and braking performance. It also reduces the risk of tire blowouts and accidents.

Extended Tire Life: Underinflation can cause uneven wear and tear on tires, leading to premature failure. Proper inflation promotes even wear and extends the lifespan of your tires.
*
Smoother Ride: Overinflated tires can create a harsh and bumpy ride. Properly inflated tires provide a smoother and more comfortable driving experience.
Conclusion
Checking your tire pressure regularly is a simple yet essential maintenance task. The penny test can be a helpful tool for quickly assessing tire inflation, but it’s crucial to use a tire pressure gauge for accurate readings. Maintaining proper tire pressure ensures safe driving, improves fuel efficiency, extends tire life, and enhances overall vehicle performance.
Frequently Asked Questions: Checking Tires with a Penny
How do I know if my tires are too low?
Insert a penny into the tread groove of your tire with Lincoln’s head upside down. If you can see the top of Lincoln’s head, your tire tread is too low and needs air. If you can’t see the top of his head, your tread depth is likely sufficient.
What does the penny test tell me?
The penny test is a quick and easy way to check the tread depth of your tires. It doesn’t provide an exact measurement, but it gives you a general idea of whether your tires need replacing.
Can I use other coins besides a penny?
While a penny is the most common and recommended coin for this test, you can also use other coins with similar dimensions. Just make sure the coin’s edge is flush with the tread groove.
How often should I check my tire pressure?
It’s a good idea to check your tire pressure at least once a month, and before any long trips. You should also check your pressure when your tires are cold (haven’t been driven on for at least three hours).
What happens if my tires are underinflated?
Underinflated tires can lead to a number of problems, including reduced fuel efficiency, increased wear and tear, and a higher risk of blowouts.
