Steps
for Maintaining Proper Tire Pressure
- Step 1: Locate the recommended tire
pressure on the vehicle's tire information placard, certification
label, or in the owner's manual.
- Step 2: Record
the tire pressure of all tires.
- Step
3: If the tire pressure is too
high in any of the tires, slowly release air by gently pressing
on the tire valve stem with the edge of your tire gauge until
you get to the correct pressure.
- Step 4: If the tire
pressure is too low, note the difference between the measured
tire pressure and the correct tire pressure. These "missing" pounds
of pressure are what you will need to add.
- Step 5: At a service
station, add the missing pounds of air pressure to each tire
that is under inflated.
- Step 6: Check
all the tires to make sure they have the same air pressure
(except in cases in which the front and rear tires are supposed
to have different amounts of pressure).
If you have been driving your vehicle
and think that a tire is under inflated, fill it to the recommended
cold inflation pressure indicated on your vehicle's tire information
placard or certification label. While your tire may still be
slightly under inflated due to the extra pounds of pressure in
the warm tire, it is safer to drive with air pressure that is
slightly lower than the vehicle manufacturer's recommended cold
inflation pressure than to drive with a significantly under inflated
tire. Since this is a temporary fix, don't forget to recheck
and adjust the tire's pressure when you can obtain a cold reading.
