How to Measure Tire Tread Depth

Knowing your tread depth can be quite useful when it comes to determining when you need new tires and how many tires to replace. There are 2 different ways you can check it yourself, and they both only take a minute or two! Using either method, it’s best to measure at least 3 different spots on the tire (the middle of the tread and closer to each sidewall).


Use a Tread Gauge



These can easily be found at most gas stations and/or department stores. They are small, inexpensive, and are a great tool to have in your car at all times. Instructions will be included on the packaging, and they are very easy to use.




Do the Penny Test




Stick a Lincoln penny in the tread, head down. If you can see the top of Lincoln’s head, then your tires only have 2/32nds or less of tread left and you definitely need new tires! See the image below for when it might be time to start thinking of replacing your tires, too.



If you don’t have a tread gauge or spare penny on hand, stop by any of Wiygul Automotive Clinic’s locations. Our techs will gladly inspect your tires and let you know how much tread you have left!
