So we all know that the Penny Test works on tires that you get from places that sell Wholesale Used Tires & regular Manufacturers .. right? If you don’t, just read the blog about it. Anyway, there’s something new called the “Quarter Test”. Let’s get a thorough explanation on all tests, shall we? 

The Original Penny Test 

–When you place your penny upside down on the tread of your tire, you have 2/32” of tread depth left.

–If you turn it around & the top of the Lincoln Memorial is covered, you have 6/32” of tread depth left. 

The Quarter Test

–Place a quarter upside down; just like you would the penny. If Washington’s head just so happens to always be covered by the tread, you have 4/32” of tread depth left. 

–So now if you don’t have a penny, you can use a Quarter; or vice versa.

Just like the Penny Test, it shouldn’t matter if you look at your Tires by Size , the Quarter Test should work (:

Do you happen to know the size of your tire? If not, that’s totally fine; that just makes two of us. 

Let’s pretend your tire says something like “225/50R16”. The first number that you see would be the width (225). The second number is considered to be the profile of the tire (50). Last, but most definitely not least; “R16” is the actual size of your 16″ Used Tires .. or wheel. So say you need a new rim or hubcap, when they ask you for the size, you’d simply say, “I need a 16 inch _______.” 

Please keep in mind that this is only an example & all tires have different numbers; this is only something to refer to, but if you have any questions, you can look for Tires by Size on our All-Used-Tires.com site (:

It’s easy right?

Tire Irons, basically, are tools used to install & remove tires from your vehicle! There’s really no other way of putting it; to be perfectly honest. If you use it right, it should detach the nuts that are used to hold the wheel in place, along with the tire that comes around the rim. If you wouldn’t know how to do this on your own (like me), you can just go to your local Auto Shop & they should have one. 

You won’t really see people on the road changing their tire with a Tire Iron considering we have Triple A now-a-days; but a lot of Auto Repair shops still use Tire Irons to replace old tires with new ones. They look at Tires by Size ; like if they’re 20″ Used Tires or even 24″ Used Tires , to make sure they’re using the right amount of pressure. Many people would refer to them as Lug Wrenches, but it’s essentially the same thing. 

So if you need to change your tire for whatever reason, now you know the most important tool: a Tire Iron.

The Penny Test is something that has been used for years to determine the tread on a tire. What’s cool is that all you really need is a penny & a couple of fingers; literally. It doesn’t matter if you have 12″ Used Tires or 19″ Used Tires ; it should all be the same.

1. Reach into your pocket, or wallet; wherever you carry pennies, & hold it between your thumb & your forefinger. Make sure Lincoln’s head is the side of the penny that’s facing you. 

2. After you’ve completed this extremely hard task, glide the penny between the tread grooves on your tire. When you do this, be sure that Lincoln’s top part of his head is the part touching the tire; so essentially, the penny will be upside down at this point. 

3. As you’re gliding the penny, if you see Lincoln’s head completely, then I’d say it’d be time to change your tires. If there is any point where Lincoln’s head is blocked by the tread, then you’ll be fine (:

Hope this helps,
