Inflation
--
Tire Pressure
The Certificationflire 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
0
Bad handling
Rough ride
Needless damage from road hazards
When
to
Check
Check your tires once a month or more.
Also, check the tire pressure
of
the spare tire.
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
7,500
miles
(12,500
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 When It Is Time
for
New Tires
on
page
5-68
and Wheel Replacement
on
page
5-72
for more information.
Make sure the spare tire is stored securely. Push, pull,
and then try
to
rotate or turn the tire. If
it
moves,
use the wheel wrench and jack handle extensions
to
tighten the cable. See Changing a
Flat
Tire
on
page
