Ample tread depth is vital for tire health. If treads are worn too thin, then it’s time for replacement. One way to determine tread wear is by performing a visual examination of the tire wear bars. Learn how to read the wear bars and act accordingly.

What are wear bars?

Throughout the tire, you’ll see a set of bars in the tire grooves. These are the tire wear bars, also known as indicator bars. In a healthy tire, the tread should exceed the height of the wear bars. If it’s flush with the bars, that’s an indication that the treads are worn thin and need replacement. Apart from a visual inspection, you can also run your fingers over the tread; if you can feel the bars, then the treads are no longer at a sufficient depth.

Regardless of the tire brand and tire size, most tire types, including all-season and winter varieties, include indicator bars throughout the surface.

Other Ways to Measure Tread Wear

If you’re unable to locate the wear bars or just aren’t certain if they’re aligned with the treads, you may need to perform additional tests. You can use a tire depth gauge, which you can purchase for about $5 at your local auto store. This gives you a precise measurement of tread depth. Replacement is necessary if the gauge indicates a depth of 4/32-inches or lower.

Another easy DIY test is the penny test. Insert a penny upside down into the tire’s groove. If the top of Abe Lincoln’s head is visible, then you need to replace the tire.
