TAKE THE PENNY TESTTread is a series of grooves which provide your car’s tires with traction. These grooves between tread blocks act as channels that divert water, snow, and other slick elements away from the tire to help you maintain traction on slippery surfaces. Without tread, those elements can lift your tires off the road.

When is it Time to Replace Your Tires?Tire tread depth in the U.S. is measured in 32nds of an inch, and several states require you to replace them when depth falls to 2/32". The U.S. Department of Transportation also recommends replacing your tires when they diminish to that depth.
How Can You Check the Tread Depth of Your Tires?Some tires have tread wear bars that will indicate when tire tread reaches 2/32::. Tread depth gauges are also available at Pep Boys. But the easiest way to determine the depth of your tire's tread is by giving them the "penny test."
What is the Penny Test?The penny test is an easy and accurate way to measure tire tread depth.
Take a penny and place it between the tire tread blocks with Lincoln’s head upside down and facing you. If Lincoln's head is buried, your tires still have more than 2/32" of tread. Your tires need to be replaced if the head is visible.
Regardless of whether you use the penny test or a depth gauge to determine your tread depth, it is important to test your tires in multiple areas. Misalignment, not rotating your tires, and other issues can cause uneven wear. Schedule an appointment at your local Pep Boys if it's time to replace your tires or you're in need of a wheel alignment or tire rotation.
