How to check tire tread depth

Where are the wear bars? And what do they have to do with tire life and safety? Watch as our pro reveals how to properly check your tires’ tread depth in this short video:

Tire tread depth is measured in 32nds of an inch, with most new tires starting with 10/32” or 11/32” of tread depth. When tire tread reaches 2/32”, the tires are considered unsafe.  

Two easy ways to check tire tread depth:

  1. Wear bars: Visually inspect the raised wear bars running perpendicular to the tread pattern. If the tread is above the wear bars, the tires still have life. If it’s flush, it’s time for new tires—wears bars are set at 2/32″.
  2. Tire tread gauge: Pick-up a tire tread gauge from your local auto parts store (it’s relatively inexpensive), rest it on the top surface of the tire tread and extend the indicator into one of the tread patterns. Again, if it shows tread depth at or below 2/32”, it’s time for new tires.
