It's important to have the proper air pressure in your tires, as  shown on the vehicle door edge, door post, glove box or fuel door. It is also listed in the owner's manual.

1.When you check the air pressure, ensure that the tires are cool - meaning they are not hot from driving even a mile. ( NOTE: if you have to drive to get air, check and record the tire pressure first and add the appropriate air pressure when you get to the pump. It is normal for tires to heat up causing the air pressure inside to increase as you drive. Never "bleed" or reduce air pressure when tires are hot.)

2. Remove the cap from the valve on the one tire.

3. Firmly press a tire gauge onto the valve.

4. Add air to achieve recommended air pressure.

5. If you overfill the tire, release air by pushing on the metal stem in the center of the valve with a fingernail or the tip of a pen. Then recheck the pressure with your tire gauge.

6. Replace the valve cap.

7. Repeat with each tire, including the spare. (Note: Some spare tires require higher inflation pressure.)

8. Visually inspect the tires to ensure that there are no nails or other objects embedded in the tire that could poke a hole and cause an air leak.

9. Check the sidewalls for any gouges, cuts, bulges or other irregularities.

NOTE: Air pressure in a tire goes up (in warm weather) or down (in cold weather) 1-2 pounds for every 10 degrees of temperature change.
