Checking tire pressure is simple and only takes a few minutes, but it makes a big difference for safety, fuel economy, and tire life.

Quick Scoop

  • Use a tire gauge and check pressures when the tires are cold (car parked for at least 3 hours or first thing in the morning).
  • Aim for the pressure listed on the sticker in your driver’s door jamb or in the owner’s manual, not the number on the tire sidewall.
  • Check all four tires (and the spare if you have one) at least once a month and before long trips.

Step‑by‑step: How to check

  1. Park on level ground and let the tires cool if you’ve been driving.
  1. Find the recommended PSI on the door sticker or in the owner’s manual.
  1. Remove the valve cap from the tire’s valve stem and put it in your pocket.
  1. Press the tire gauge straight and firmly onto the valve stem; a brief hiss is normal.
  1. Read the gauge (analog: dial or sliding bar; digital: number on the screen).
  1. Compare to the recommended PSI:
    • If low, add air with a compressor, then recheck.
 * If high, press the gauge’s little pin or the valve core briefly to let air out, then recheck.
  1. Repeat for all tires and replace every valve cap.

How to add or release air

  • At a gas station compressor or home pump, push the hose nozzle straight onto the valve until you hear/feel air going in; hold for several seconds, then check with a gauge.
  • To release air, briefly press the center pin inside the valve with the back of the gauge until you hear air escape, then measure again.

Safety & timing tips

  • Underinflated tires can overheat, wear quickly, and make the car feel squishy or pull, while overinflated tires reduce grip and ride comfort.
  • Temperature changes (like season changes) can drop pressure, so checks are especially important in colder months.
