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
Wa).
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 “When It’s Time
for
New Tires” and
“Wheel Replacement” later
in
this section for
more information.
The purpose
of
regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
