How To Check Your Tires’ Air Pressure

Making sure your air pressure is correct will get you a safer, smoother ride, longer-lasting treads, and – most importantly – peace of mind.

Instructions

  • Step 1: Remove the gauge and check the reading.
  • TIP: It’s best to check tire pressure in the morning before you start driving; the gauge reading won’t be accurate if the car has been on the road for a while.
  • Step 2: If the pressure is high, let some air out of the tire. Use the small nib on the back of the pressure gauge to depress the tire valve. Check the pressure again and keep letting out air until you reach the right amount.
  • Step 3: Uncap the tire stem and press the tire gauge onto the opening until it’s firmly attached. If you can hear air escaping, reposition the gauge until it stops.
  • TIP: The number posted on your tire is the maximum air capacity—never exceed this number.
  • Step 4: If the air is low, locate an air compressor, usually at a gas station. Place the air hose nozzle over the tire valve and push down. Keep checking your tire pressure until it’s at the optimal reading.
  • Step 5: Make sure you check all 4 tires and fill each as needed.
  • Step 6: Check how much air each tire should hold by consulting the factory recommendation sticker, located inside either the driver’s side door or the glove compartment. If you can’t find the sticker, or if you can find it but can’t read it, check your owner’s manual.
  • FACT: An estimated 32 million cars on the road have at least two tires that are under-inflated.
