Tire
Pressure
The CertificatiodTire 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 a mile.
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:
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:
Unusual wear
Bad handling
Rough ride
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. Simply looking
at the tires will not tell you the pressure, especially if you have radial tires
-
which may
look
properly inflated even
if
they’re underinflated.
If your tires
have
valve caps, be sure to put them back on. They help prevent
leaks by keeping
out
dirt and moisture.
