How Do I Check Tire Tread Depth

close up of tire tread


If you are constantly commuting, your tire treads are bound to wear down over time. You might be asking yourself, “How do I check tire tread depth?” Fortunately, the process is incredibly simple and requires only a ruler or a penny. Learn more about tire tread depth and how to check tire pressure with Pepe Auto Group, and visit our service department for more information.

What is the Recommended Tire Tread Depth?

New tires ideally have a tread depth of 10/32 or 11/32 of an inch (about a third of an inch). Once your tire tread depth reaches 2/32 of an inch, it’s time for a replacement. Other types of winter, off-roading, and truck tires have deeper tread depths. If you require a tire replacement, come visit our tire center for a tire inspection to get you back on Stamford roads in no time.

How to Check Tire Tread Depth with a Penny

Typically a ruler is the most accurate way to measure tire tread depth, a penny works in a pinch! Follow the steps below to check the tire tread depth:

  1. Insert a penny head-first into the tire tread groove.
  2. If Lincoln’s head is no longer visible and is covered by the grooves, your tire tread is fine.
  3. If you see all of Lincoln’s head, that means you need to replace your tire.
  4. Repeat this process on all four tires and try the test on multiple locations on each tire.

Other Methods to Check Tire Tread Depth

Here are a couple of other ways you can check your tread depth: 

  • Tread Depth Gauge– Insert the probe into the shallowest tread groove, and then press the top bar of the gauge flat against the tire to see the rating of the treadwear. You can purchase this at a local hardware store.
  • Tread Wear Bars: Most tires have tread wear indicator bars built-in, and they are located at the bottom of the tread groove on the tire in multiple locations. If the bars are flushed with the tire rib that surrounds them, it shows that the tire needs a change.

How to Check Tire Pressure

Overinflated and underinflated tires can at best be an immense nuisance and at worst be hazardous to you or your fellow drivers. Therefore, you should check the tire pressure with a tire pressure gauge every once in a while:

  • Remove the valve from the tire.
  • Press the tire pressure gauge onto the valve and hold it there
  • Take note of the pressure reading and compare it to the manufacturer’s specifications
  • Adjust tire pressure
  • Reinstall the valve cap
