Today through this article, First of all, it is important to know what exactly is Tire Tread Depth.
What is Tire Tread Depth?
Tire Tread Depth is the distance between the top surface of your tire and the bottom surface of the tire tread, you can also say the bottom surface of the groove in your tire.
For pictorial representation, please check the below image….

The tire tread depth in the United States is measured in 32nds of an inch. The new tires have 10/32” or 11/32”.
However, some trucks, winter tires, and SUVs might have bigger tread depths than normal tires.
The tire tread depth conveys the condition of your tire. If you look technically the measurement is as below:
S.no | Tire tread depth | Remarks |
1 | 6/32” | Sufficient tire tread depth |
2 | 5/32” | Wet roads are dangerous, Consider tire replacement |
3 | 4/32” | Replace tires ASAP |
4 | 3/32” | Immediately replace your tires, Legally bald tires |
Which Tread Depth to choose?
The U.S Department of Transportation recommends that the tires should be replaced when you see 2/32” tread depth.
Any delay will only cause unforeseen circumstances. It is always recommended that tires should be replaced as soon as you see 4/32”.
However, most tire manufacturers suggest that during winter it’s better to replace when your tires reach 4/32” and during summer when you see it as 2/32”

Pro Tip to Remember:
Remember to place the penny’s Lincoln facing towards you and the head upside down. Head into the tread.
The tire tread has several ribs, it’s an extruded portion of the tread.
Once you place the penny on the tread, if you don’t see Lincoln’s head then your tires are great.
But if you see the top of Lincoln’s head that means your tire has worn out and it’s time for you to go for some tire shopping.
Below is the pictorial representation of the penny test evaluation:

While checking the tire make sure to check all sides of the tire and not limit it to a particular area.
CHECK ALL THE TIRES and take note of the orientation of the penny while checking.
While doing the penny test, some areas will fail, and some areas will pass. You must consider this a failure overall. Because the penny test doesn’t guarantee the overall legal values for tread depth.
Hence, you can check professionally with a depth gauge to be more accurate in terms of legal requirements.
Most importantly, if you have any doubts about your tread depth measurements, you must always check them with a licensed mechanic.
Driving with a proper tread depth tire is a vital requirement for your safety. Hence, check with your mechanic and consider replacing the tire.
