Measuring Tread Depth
The United States measures tire treads by ever 32nd of an inch with most brand-new tires offering a depth of around 10/32nds of an inch. Once your tread depths reach around 4/32nds of an inch, keep an eye on them. They will need to be replaced soon.
- At 4/32'', your tires are still okay.
- Tires need to be replaced soon at 3/32''.
- Replace tires now if tread depths are at 2/32'' or less.

Do Your Tires Pass the Penny Test?The penny test is one of the easiest ways to determine whether you need new tires. All you need to do is find a penny and insert it Lincoln's head down into the tread groove of your tires. Depending on the results of the penny test, you may need new tires immediately.
How to Read Penny Test Results
- If you see all of Lincoln's head, your tread depths are less than 2/32''. Replace your tires.
- Your tires will need to be replaced soon, but not right away, if Lincoln's head is only partially exposed.
Quarter Test - A Penny Test Alternative
Don't have a penny on hand? No worries! A quarter will do just fine.
When conducting the quarter test, insert the coin into the tire tread the same way you would with the penny. This time-wait for it-put Washington head-first into the tread.
Â
If Washington's head is partially covered, you have at least 4/32'' of tread depth left. Replacing your tires should be on your radar at this point, as you don't want your treads to get much shallower.
