Measuring tire tread depth with a coin is a simple and effective way to check if your tires are still safe to use. Here's how you can do it using a penny:

  1. Grab a penny: Make sure it's clean so you can see the details clearly.
  2. Insert the penny: Place the penny into the tread groove with Lincoln's head pointing down.
  3. Check the tread: If you can see the top of Lincoln's head, your tread is less than 2/32 of an inch deep, and it's time to replace your tires. If part of his head is covered, your tread is still above 2/32 of an inch and your tires are in better shape⁴⁵.
  4. For a more proactive approach, you can use a quarter instead. Insert the quarter with Washington's head down. If the tread covers part of Washington's head, your tread depth is above 4/32 of an inch, which is better for wet conditions⁴.

Regularly checking your tire tread can help you maintain better traction and safety on the road. Do you have any other questions about car maintenance or anything else?
