How To Tell If You Need New Tires
Tire Tips
The Penny Test
In the United States, tire tread depth is measured in 32nds of an inch.
The U.S. Department of Transportation recommends replacing tires when they reach 2/32 of an inch.
The idea of the penny test is to check whether you’ve hit the 2/32” threshold.
Here’s how it works:
- Place a penny between the tread ribs on your tire. A “rib” refers to the raised portion of tread that spans the circumference of your tire. Tire tread is composed of several ribs.
- Turn the penny so that Lincoln’s head points down into the tread.
- See if the top of his head disappears between the ribs. If it does, your tread is still above 2/32” , If you can see his entire head, it may be time to replace the tire because your tread is no longer deep enough.
Use A Thread Depth Gauge
Using a thread depth gauge is as simple as the penny test. Simply stick the probe into a groove in the tread and press the shoulders of the probe flat against the tread block and read the result. The gauge should measure in both 32nds of an inch and millimeters.
