14. Do the “Penny Test”

Items Needed: A penny
Est. Price: $0.01*

For this trick, you can use that penny that’s stuck under your couch cushions or that you found in the pocket of your pants. To find out if it is time to buy new tires, the penny test will help you make the difficult decision.

Take the penny and place it upside down so that the top of Lincoln’s head is facing the floor. Then dip the penny into the tread to check its depth. If the tread goes across Lincoln’s forehead, then the tires still have some life. If not, Lincoln recommends we buy new ones.
