Storing a Flat or Spare Tire and Tools
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come
off. This could lead to an accident.
Be sure to use the correct wheel nuts.
If yo11 have
to replace them, be sure to get new GILI original
equipment wheel nuts.
Stop somewhere as soon
as you can and have the
nuts tightened with
a torque wrench to 95 Ib-ft
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
' A CAUTION:
-
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause in,jury. In

Make sure the tire and carrier are secure.
Driving with the tire or carrier unlatched could
injure pedestrians or damage the vehicle.
Compact Spare Tire (If Equipped)
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Wa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact
spare is made to perform well at speeds up to
65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where
you want. Of course, it’s best
to replace your spare with a full-size tire as
soon as you
can. Your spare will last longer and be in good shape in
case you need it again.

Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “1,oading Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check
all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread
is badly worn, or if‘ your tires have
been damaged, replace them.
Inflation -- Tire Pressure
The Cel-tification/Tire label. which is 011 the driver‘s
door edge, above the door latch. shows the correct
inflation
pressures for your tires when they’re cold.
“Cold“ lneans 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
0 Tire overloading
Bad wear
0 Bad handling
0 Bad fuel economy.
NOTICE: (Continued)

I NOTICE: (Continued) I
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 n101-e. Also. check the
tire pressure
of the spare tire.
I! you have a compact spare tire. it should be at 60 psi
(420
k Pa).
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 thcm. Radial tires may look
properly inflated even when they're underintlatecl.
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 s11o111d be rotated every 6,000 to 8,000 miles
( IO 000 to 13 000 km). Any time you notice unusual
we;^. rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See "When 1t.s Time for New Tires" and
"Wheel Replacement" later
in this section for
more information.
Thc purpose
of' reg~~lar rotation is to achieve more
uniform wear
fur all tires on the vehicle. The first
rotation
is thu most important. See "Schecluled
Maintenance Services"
in the Index for scheduled
rotation intervals.
