How Do I Check Tire Tread Depth?

Looking to answer the question “How do I check tire tread wear?” It’s really very easy to check the tire depth on your car by simply using a ruler or a penny. Learn more from the tire experts at Suntrup Automotive Group.

What is the Recommended Tire Tread Depth?

The tread depth of a new tire is generally 10/32 to 11/32 of an inch, or about a third of an inch. Winter tires, off-road tires, and some truck and SUV tires often have even deeper tread grooves.

The U.S. Department of Transportation recommends replacing your tires when the tire tread depth gets down to about 2/32 of an inch. Making sure that your tires have the correct tread depth will ensure that you enjoy safe driving in the St. Louis area, and by having your tires routinely rotated, you can even extend the life of your tires.

The Penny Test

The best way to measure tire tread depth is with a ruler, but if you’re out-and-about, a penny will do the trick. Follow these steps to check the tread depth remaining on your tires:

  1. Insert a penny with Lincoln’s head upside down into a tire tread groove.
  2. If Lincoln’s head is covered and no longer visible between the grooves, your tread depth is good.
  3. If you can see all of Lincoln’s face, it means that the tire tread is 2/32 inches deep or less and it’s time to replace them.
  4. Repeat this process on all four tires and in multiple locations on each tire.

More Ways to Check Tire Health

There are special tools, such as a tire tread depth gauge, that you can use to check your tires. Many tires also come with tread wear bars that have a visible mark built into the tire which indicates the 2/32 inch mark. Whenever you check your tire tread depth, you should also:

  • Check the tire pressure.
  • Inspect for any visible damage to the tread or sidewalls.
  • Check for any tire rot or disintegration.
  • Check to see if the wear is uneven. If so you should bring your car into the Suntrup Automotive Group service center near you for a tire rotation or wheel alignment.
