There are two main ways to check your tire tread depth to see if it's time for new tires:

1. The Penny Test (Easy, Approximate Method):

This is a quick and easy way to get a rough estimate of your tread depth. Here's how to do it:

  • Grab a penny.
  • Hold the penny with Lincoln's head facing down and insert it into the tread groove of your tire.
  • If you can see all of Lincoln's head, your tread depth is likely below 2/32 of an inch, which is the minimum safe limit according to most tire manufacturers. It's time to start thinking about replacing your tires.
  • If part of Lincoln's head is obscured by the tread, your tires are probably still in good condition.

2. Using a Tread Depth Gauge (More Accurate Method):

A tread depth gauge is a small, inexpensive tool that provides a more precise measurement of your tire tread depth. Here's how to use one:

  • Purchase a tread depth gauge. They are readily available at auto parts stores, online retailers, or even included in some roadside emergency kits.
  • Insert the tread depth gauge prong straight down into a tread groove.
  • The gauge will have a depth scale. Look at the measurement where the tread touches the gauge.
  • Consult your tire manufacturer's recommendations for the minimum safe tread depth for your specific tires. This information is usually printed on the tire sidewall. Most recommend replacing tires when the tread depth reaches 2/32 inches or less.

Here are some additional tips for checking your tire tread:

  • Check all four tires, including the spare.
  • Do the tread depth check in multiple locations around each tire. Tread wear can be uneven.
  • Look for signs of uneven tread wear. This could indicate alignment problems or other issues that need to be addressed.

By regularly checking your tire tread depth, you can help ensure your safety on the road and avoid unexpected tire failures.
