Tires need the correct amount of air pressure to operate effectively.
Notice: Do not let anyone tell you
that under-inflation or over-inflation is all right. It is not. If your
tires do not have enough air (under-inflation), you can get the following:
• | Premature or irregular wear |
If your tires have too much air (over-inflation),
you can get the following:
• | Needless damage from road hazards |
A Tire and Loading Information label is attached to the vehicle's center pillar
(B-pillar), below the driver's door lock post (striker). This label lists your vehicle's
original equipment tires and their recommended cold tire inflation pressures. The
recommended cold tire inflation pressure, shown on the label, is the minimum amount
of air pressure needed to support your vehicle's maximum load carrying capacity.
For additional information regarding how much weight your vehicle can carry,
and an example of the tire and loading information label, see

When to Check
Check your tires once a month or more. Do not forget to check the spare tire.

How to Check
Use a good quality pocket-type gage to check tire pressure. You cannot tell
if your tires are properly inflated simply by looking at them. Radial tires may look
properly inflated even when they're underinflated. Check the tire's inflation pressure
when the tires are cold. Cold means your vehicle has been sitting for at least three
hours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press the tire gage firmly onto
the valve to get a pressure measurement. If the cold tire inflation pressure matches
the recommended pressure on the Tire and Loading Information label, no further adjustment
is necessary. If the inflation pressure is low, add air until you reach the recommended
amount.
If you overfill the tire, release air by pushing on the metal stem in the center
of the tire valve. Recheck the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems. They help prevent leaks
by keeping out dirt and moisture.
