How can I use a tire pressure gauge to check the pressure of my tires effectively?

To effectively check the pressure of your tires using a tire pressure gauge, follow these steps:

1. Remove the valve cap from the tire valve stem.
2. Press the tire pressure gauge firmly onto the valve stem to get a reading.
3. Read the pressure displayed on the gauge.
4. Compare the reading to the recommended pressure for your vehicle, which can usually be found in the owner's manual or on a sticker inside the driver's side door jamb.
5. If the pressure is too low, add air until it reaches the recommended level. If it is too high, release some air until it is correct.
6. Repeat the process for all four tires, including the spare tire.
