You tires have a close working relationship with your car’s other
mechanical systems such as the wheels, brakes, shock absorbers,
steering and suspension systems. Make sure you have a safe, comfortable
ride and good tire mileage. One of the most important things to
remember is maintaining proper tire pressure. But how do you exactly do
it?
Here are steps for maintaining proper tire pressure, according to NHTSA:
Step 1: Locate the recommended tire pressure on the vehicle's tire information placard, certification label, or in the owner's manual.
Step 2: Check 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. At a service station,
add the missing pounds of air pressure to each tire that is under
inflated.
Step 5:
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
pressure of a 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.
