Inflation
-
Tire Pressure
The Certification/Tire 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
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.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to
8,000
miles
(10
000
to 13
000
km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. See

Is Time for New Tires
