Need to measure your tread depth? Use a coin!

It's a good idea to keep track of your tires' tread depth because it indicates how much life is left in the tires. Gauges are certainly the best option for doing so, but they're not always handy. At Tire Rack, we offer the Dill® Digital Tread Depth Gauge in our inventory of accessories. (Bonus! You can also use it to measure brake shoe and pad wear!)

Another way to measure tread depth—use a coin!
Place a penny or a quarter into several tread grooves at least 15" apart on the tire. When part of Lincoln's head is covered, it means you have more than 2/32" of tread depth. And if the top of his memorial is always covered, then you've got more than 6/32" of tread depth. When part of Washington's head is covered, then you're clear with more than 4/32" of tread depth.

So easy, right? Just remember that most states determine tires are legally worn out if their tread depth gets below 2/32"—in other words, below Lincoln's head. Read more, then click here to order new tires if yours are significantly worn out.

I'll start by complementing your site!! I found very useful info. I recently bought a used 2004 hyundai santa fe from a dealer, my problem is that I think that I've been cheated on the tires, I tried the penny, the thread doesn't make to Lincolns head, I need a gauge in case they don't want to replace'em I can take them to court. Do you carry a cheaper gauge other than the digital?
