Inflation
--
Tire Pressure
The Certificationnire label, which is on the driver's door
edge, above the door latch, 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:
0
Too much flexing
Too much heat
0
Tire overloading
Bad wear
0
Bad handling
0
Bad fuel economy
If your tires have too much air (overinflation), you
can get the following:
0
Unusual wear
0
Bad handling
0
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.
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 5-55 and Wheel Replacement
on
page 5-58 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 to tighten the cable. See
Changing a Flat Tire
on
page 5-62.
