Things are getting a little chilly here at Mercedes-Benz of Danbury! But, we still need to prepare our vehicles for whatever we may encounter and one service that is frequently overlooked is the tread on your tires. Don’t worry – we all do it, we’re all guilty of it but this week we want to teach you how to check from the comfort of your very own driveway! So, check that out below and let us know if we can be of assistance to you and your tires! 

You should be monitoring your tread depth closely once it reaches 4/32 inches deep. Wait a minute… what do these measurements mean in the first place? We have you covered there. Below, you will see when your tires still have good tread, when you’ll need to replace them soon, and when you probably should have already replaced them. 
 
  • 4/32” or deeper = good tread 
  • 3/32” = replace tires soon 
  • 2/32” = replace tires now 

Okay, but are you supposed to measure that tread? We have you covered there with a few, simple ways to check that treat, and seriously you won’t need anything more than some loose change! 

The penny test: Insert a penny into your tire’s tread groove with Lincoln’s head upside down into the tread facing toward you. If you can see all of the head, your tread depth is less than 2/32” and it is time to replace your tires. 

The quarter test: do the same test with a quarter and if the tread reaches Washington’s head, you have at least 4/32” of tread remaining. This means that your tires are still in good shape! No need to worry!

No change? No problem! Take a look at your tread wear indicator bar that is molded into the tread of your tires. Bars are located at the bottom of tread grooves in multiple locations; when these bars are visibly flush with the adjacent ribs, your tire has no more than 2/32” of tread left. If you see this, it’s definitely time to replace those tires as soon as possible. So come see our team today!
