-
When you check the air pressure, make sure the tires are cold ―meaning they are not hot from driving even a mile.
-
Remove the cap from the valve on one tire.
-
Firmly press a tire gauge onto the valve.
-
Add air to achieve recommended air pressure.
-
If you overfill the tire, release air by pushing on the metal stem in the center of the valve. Then recheck the pressure with your tire gauge.
-
Replace the valve cap.
-
Repeat with each tire, including the spare.
Some spare tires require higher inflation pressure.
-
Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air leak.
-
Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or other irregularities.
