How to Check Tire Air Pressure

Whether you use your vehicle for work, play, or both, a lot is riding on your tires. It is important to keep them maintained. A huge part of keeping tires maintained is keeping them properly inflated. If your tires are underinflated or overinflated, it can cause premature tread wear which will reduce the life of your tire or cause tire failure. Proper inflation provides greater steering response, better fuel efficiency, and a smoother ride.

To ensure that your tires are inflated according to manufacturer standards it is recommended that you check tire pressure at least once a month. Knowing how to use a tire gauge to check your tires is an important skill to know. You will need a tire gauge, an air compressor, a pen, and paper. Here is how you check the pressure and refill your tire.

  • Step One: Start with cold tires if possible, which means tires that have been parked for more than three hours. Your tire gauge measures pressure in pounds per square inch (psi).
  • Step Two: Check for recommended psi, you can find this in your vehicle's owner’s manual, or you can look at the door jamb on the driver’s side and find the recommended psi for your tire inflation guidelines. If you are unable to find the information in your manual or door jamb, consult the manufacturer, your vehicle dealer, or a qualified tire professional.
  • Step Three: Some vehicles have different tire pressures for front and rear tires. Write down the recommended pressures for each so you do not get confused.
  • Step Four: Remove the valve cap from one of your tires and push the tire gauge hard onto the valve until the hissing stops. At this point, the gauge should give you a reading on the psi of the tire. Write this number down and repeat the process with each of your tires.
  • Step Four: Use the air compressor to fill the tires to their recommended levels. You will have to inflate the tire for 10-30 seconds at a time and check the pressure each time until the gauge shows that your tires meet the recommended criteria. Note: If your tires are “hot” you can add up to four psi to the pressure. Just be sure you go back and check pressure after parking your vehicle for at least three hours. If you need to take the air out of the tires, most gauges have a nub on the back of the tire gauge that you can push against the inside of the valve stem to release some air pressure. Just release in quick bursts and re-check the pressure each time.
  • Step Five: Repeat this procedure for each tire until all four tires are at recommended pressure levels.
