No one wants to drive on worn, unsafe tires, so learning how to measure tire tread depth will help you know when it’s time for some new replacements. There are a number of simple ways to do this yourself, from the well-known penny test, to using a specially-designed tire tread depth gauge.

WHAT IS THE RECOMMENDED MINIMUM TIRE TREAD DEPTH?

Your average brand-new tires come with 10/32″ or 11/32″ tire tread depths, and if you’re driving a truck or SUV, they may be even deeper. So, when you check your tire tread depth, 2/32″ is the magic number. It represents the minimum threshold for safe driving. When you get close to 2/32″, you can expect to see a decrease in your tire performance, especially in inclement weather conditions. At this point, it’s time to take your vehicle in for tire service.

THE PENNY TEST

If you feel like your tires may be getting worn out, the penny test is a simple way to check your tread depth. Take a penny, and place it in the groove created by your tread ribs, which are the raised part of your tire. Point Lincoln’s head down into the tread, and see if it disappears inside the ribs. It you can’t see his head, you have plenty of tread above 2/32″. If you can see his whole head, your tread is getting worn out. Perform this test on all of your tires and in various spots on each tire. If anywhere falls below the 2/32″ mark, replace your tires.

TIRE TREAD DEPTH GAUGE

Tire tread depth gauges are available at any auto parts store and are another easy way to measure your available tread. They’re designed to provide an exact measurement in thirty-seconds of an inch and millimeters. Your tires are also equipped with indicator bars that show when the tread has reached its limit.
