Inflation
-
Tire Pressure
The Certificationrrire label, which is on the rear edge of
the driver’s door, shows the correct inflation pressures
for your tires when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven
no more than
1
mile
(1.6
km).
Notice:
Don’t let anyone tell you that underinflation
or overinflation
is
all right.
It’s
not. If your tires
don’t have enough air (underinflation), you can get
the following:
Too
much flexing
Too
much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy
If your tires have
too
much air (overinflation), you
can get the following:
Unusual wear
Bad handling
Rough ride
0
Needless damage from road hazards
When
to
Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be
at
60
psi
(420
kPa).
How
to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if
your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back
on
the valve stems.
They help prevent leaks by keeping out dirt and moisture.
Check Tire Pressure System
Your vehicle may have a check tire pressure system
that can alert you to a large change in the pressure of
one tire. The system won’t alert you before you drive
that a tire is low or flat. You must begin driving before
the system will work properly.
