The tire tread of your car is essential. A good impression increases your road stability and prevents you from skidding off the road as you go around a corner. It’s simple to check your tire tread (a toonie is the only instrument you need!). How to check the tire tread of your car: Step-by-Step
- Put the toonie’s outer edge into the tread of your tire.
- Your tires are probably pretty fresh if the tread touches the bear’s paws.
- They’re around 50 percent worn if it reaches into the silver.
- It’s time to search for new tires if your tire tread reaches just about half-way through the letters.
Tip: You can purchase a tread depth gauge at most car parts stores and gas stations if you are looking for more precise measurement. Were you aware? At NAPA auto parts, AMA members save 10 percent on retail priced parts and accessories.
How To Check Wear Indicators For Tire Tread?
Some tires have built-in tread wear indicators that mark the minimum permissible tread depth along the tire grooves. It’s probably time to repair your tires if these indicators are worn down.
The Penny Test
In the United States, the width of the tire tread is estimated at 32ths of an inch. Usually, new tires come with tread depths of 10/32″ or 11/32″, and some truck, SUV, and winter tires may have deeper tread depths than other versions. When they hit 2/32″, the U.S. Department of Transportation recommends replacing tires, and many states legally require replacing tires at this depth.
“The idea of the penny test is to verify that you have reached the 2/32” mark. This is how it works here:
- Place a penny on your tire between the ribs of the tread. A “rib” refers to the elevated section of the tread covering your tire’s circumference. The tire tread consists of several ribs.
- Turn the penny so that the head of Lincoln points down towards the tread.
- See if, between the ribs, the top of its head disappears. If it does, your tread is still above 2/32″ If you can see the entire head, because your tread is no longer deep enough, it might be time to change the tire.
Note to check each tire while conducting the penny tire test and check different areas around each tire. Pay careful attention to areas that looks the most worn out. Even if parts of your tread are more profound than 2/32″, if any sites fail the penny test, you can always change the tire.
Consistent wear is expected around the entire tire, but irregular wear on the tread may be a sign of improper inflation, misalignment of the wheel, or several other things. You should have a technician to check your car if you see uneven tread wear.
Tread Deep Gauge
Using a tread depth gauge is an easy way to verify your tire tread depth. At your nearest auto parts shop, you can find tire tread depth gauges. Several models are available, but a simple graduated probe gauge that is inexpensive will work just fine. All you have to do is stick the probe in the tread into a groove and press the probe’s shoulders flat against the tread block and read the outcome. For both 32nds of an inch and millimeters, both gauges should measure.
