How to Check If Car Tires are Worn

As fall and winter approach, it’s time to start thinking about car maintenance. One important thing to check is the condition of your tires. Tires can wear down over time, and driving on worn tires can be dangerous.

Here’s a quick guide on how to check if your car tires are worn.

  • Park your car on a level surface and turn off the engine
  • Find the penny test
  • Place a penny in the tread of your tire with Abe Lincoln’s head pointing down into the tread
  • If you can see all of Abe’s head, your tires are bald and need to be replaced
  • If you can see part of his head, your tires are getting close to being bald and you should consider replacing them soon
  • The quarter test is similar to the penny test but uses a quarter instead of a penny
  • Place the quarter in the tread with George Washington’s head pointing down into the tread
  • If you can see all of George Washington’s head, your tires are bald and need to be replaced immediately
  • If you can see part of his head, your tires have less than 1/8 inch (3 mm)of tread left and need to be replaced soon

How to know when it's time for new tires

Symptoms of Bad Tires

There are several symptoms of bad tires, and it’s important to be aware of them so you can replace your tires before they cause any serious damage. Here are some of the most common symptoms: 1. Uneven wear – If you notice that your tires are wearing down unevenly, it’s a sign that they’re not in good condition.

This can be caused by a number of things, including improper inflation, alignment issues, or even just driving on rough roads. 2. Cracks and bulges – If you see any cracks or bulges in your tires, it’s definitely time to replace them. These defects can cause the tire to blow out while you’re driving, which could be extremely dangerous.

3. tread depth – The tread on your tires is what provides traction, so it’s important to make sure it’s not too worn down. You can measure tread depth with a penny; if the top of Lincoln’s head is visible when you insert the coin into the tread, then the tire needs to be replaced. If you notice any of these symptoms, don’t wait to replace your tires!

Bad tires can cause all sorts of problems, from decreased performance to increased risk of accidents. So if you think there might be something wrong with your tires, get them checked out as soon as possible.

Is the Penny Test for Tires Accurate?

It’s a common question: can the penny test really tell you if your tires are safe? The answer is…maybe. While the penny test is a quick and easy way to check the tread depth of your tires, it’s not always accurate.

Here’s how the penny test works: take a penny and insert it into the tread of your tire, with Lincoln’s head pointing down. If you can see all of Lincoln’s head, your tread depth is less than 2/32nds of an inch and it’s time to replace your tires. If you can only see part of his head, your tread depth is between 2/32nds and 4/32nds of an inch, which means your tires are still safe but need to be replaced soon.

And if you can’t see any of Lincoln’s head, congratulations – you have more than 4/32nds of an inch of tread remaining on your tires! So why isn’t the penny test always accurate? First, because tire wear isn’t uniform across the entire tire.

So even if your tread looks good in one spot, there could be areas where the tread is much thinner. Second, different tire brands have different depths for their “wear bars.” These are raised bars in the bottom of the tread grooves that show when a tire has reached its minimum safe tread depth.

Depending on the brand, these wear bars may appear when there is as little as 1/16th of an inch left on the tire (or even less). The best way to know for sure if your tires are safe is to get them inspected by a qualified technician at least once a year – or more often if they seem to be wearing down faster than usual.

How Do You Check Tire Wear at Home?

It is important to check your tire tread regularly to ensure they are safe and have adequate tread depth. Here are some tips on how to check your tire wear at home: 1. Use a penny test.

Place a penny head-first into the tread of your tire. If you can see the top of Lincoln’s head, then your tread depth is less than 2/32 inch and it’s time to replace your tires. 2. Use a ruler or measuring tape.

Another way to measure tread depth is to use a ruler or measuring tape. Place the ruler or measuring tape into the deepest part of the tread groove and measure from the bottom of the device up to the top of the tread rubber. Every 1/16 inch that you measure is equal to 2/32 inch of remaining tread depth.

3. Do the quarter test . Take a quarter and place it in between the grooves of your tire with George Washington’s head upside down, facing towards you..

If you can see above Washington’s hairline, then you have less than 4/32 inches (or 3mm)of remaining tread depth and should replace your tires soon.. 4a Look for uneven wear .

Check for any signs of uneven wear on your tires, which could indicate problems with alignment, over inflation or under inflation, among other things.. Signs of uneven wear include feathered edges, scalloped shoulders, bald spots in center etc..

Anytime you notice these issues ,it’s best to take your car in for an inspection by professional as soon as possible so they can diagnose and fix any underlying problems.. 4b Look for cupping . Cupping is another type of irregular wear pattern characterized by small dips or “cups” in the tire surface.. This issue is often caused by imbalances in wheel weights , worn shocks ,and loose suspension components .. Like with other types of irregular wear patterns ,anytime you notice cupping it’s best to take your car in for an inspection so professionals can determine what might be causing this problem..

How Do I Check My Tires on My Car?

It is important to check your tires regularly to ensure they are properly inflated and in good condition. You can check your tires yourself with a few simple steps. First, find the manufacturer’s recommended tire pressure for your car and inflate or deflate your tires accordingly.

You can usually find this information on a placard inside the driver’s door frame or in the owner’s manual. Next, use a tread depth gauge to check the tread depth of each tire. The minimum acceptable tread depth is typically 4/32 of an inch.

If any of your tires fall below this, you’ll need to replace them. Finally, visually inspect each tire for signs of wear or damage such as cracks, bulges, or uneven wear. If you see any damage, have the tire repaired or replaced as soon as possible.


If you’re not sure how to tell if your car’s tires are worn, there are a few things you can check. First, take a look at the tread depth. If the tire has less than 1/16 of an inch of tread remaining, it needs to be replaced.

You can also do the penny test – insert a penny into the tire tread with Lincoln’s head facing down. If you can see all of Lincoln’s head, the tire is too worn and needs to be replaced. Another way to tell if a tire is worn is by looking for cracks or splits in the sidewall.

If you see any damage, it’s time for a new tire.
