While a penny might not buy much these days, it can be used to determine if it’s time to replace your tires. While there are other ways to check your tread depth, the time-tested “penny test” is easy, reliable, and uses tools you probably already have in the center console of the car. Consider the following overview on how placing a penny in your tire tread can prevent blowouts and lower the risk of serious accidents.

How to Perform the Penny Test

Tire tread depth is measured in 32nds of an inch, with new tires typically measuring 10/32” or 11/32”. A good rule of thumb is to replace the tire when the tread is 2/32” deep, but it can be challenging to measure tread depth precisely. However, using the “penny test” can provide clarity on the state of your tires.

All you have to do is insert the penny into one of the treads on your tire, with Lincoln’s head upside down and facing you. If he disappears into the tire, there are still some miles left on them. On the other hand, if you can see his entire head, your tread depth is less than 2/32”, and you should replace your tires.

Why Is Checking Your Tires Important?

Modern tires are reliable and capable of going thousands of miles with minimal maintenance. Unfortunately, this also makes regular tire maintenance easy to forget, which is why so many drivers only discover a problem when they’re stranded on the side of the road.

Proper tread depth allows your tires to grip the road and navigate wet or icy roads without losing control. Worn-down treads also affect your gas mileage and may leave your vehicle sluggish and hard to steer. Every time you air up your tires, pull out a penny to check the depth and have the tires replaced as soon as your tires fail the test.
