1. When you check the air pressure, make sure the
tires are cool - meaning they are not hot from driving
even a mile. (NOTE: If you have to drive a distance 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 and the air
pressure inside to go up as you drive. Never "bleed"
or reduce air pressure when tires are hot.)
2. Remove the cap from the valve on 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 make sure there are no
nails or other objects embedded that could poke a hole
in the tire and cause an air leak.
9. Check the sidewalls to make sure there are no
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.
