7. Use A Penny To Inspect Your Tires
You may use a penny to measure the tread depth in your tires to make sure you’re safe. Place the coin into the tread of the tire after flipping it so that President Abraham Lincoln’s head is looking downward. It means your tires are in good condition if the head sinks halfway through. You will have to change the tires, though, if the tread isn’t covering any of the presidents’ heads.
