The Penny Test

In order for your tires to maintain traction with the road, especially during wet conditions, it is crucial that your tires have enough tread. The tread is the rubber grooves that surround the circumference of the tire, and it wears down with time. Typically a tread depth of 4/32″ or deeper is good to go. 3/32″ means you should replace your tires soon, and anything less than 2/32″ is considered a ‘bald’ tire and should be replaced.

Because you probably can’t eyeball those measurements or use a ruler, this nifty little trick comes in handy: the penny test.

  1. Grab a penny and insert it into the tread so that Lincoln’s head points down.
  2. Evaluate how much of his head is showing.
  3. If you can see his entire head, you should run over to Plains Tire and get the tires replaced.

You may find that some areas of your tire fail the penny test, while others are deeper and pass the test. If any part of the tire is less than 2/32″, you should replace the tire. Don’t put off doing this task, as it could save you from being in an accident. Plains Tire makes replacing tires easy. Come visit us at any of our nine locations throughout Wyoming!
