17. Tighten the wheel nuts firmly in a
criss-cross sequence as shown.
11 CAUTION 'I
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 you have
to replace them, be sure to get the
right kind.
Stop somewhere as soon as you can
and have the nuts tightened with a
torque wrench to
100 pound-feet
(140 Nmm).
Don't try to put a wheel cover on your
compact spare tire.
It won't fit. Store
the wheel cover in the trunk until you
have the flat tire repaired or replaced.
I meel covers won't fit on your
compact spare. If you try to put
a
wheel cover on your compact
spare, you could damage the cover
or the spare.

18. Store the flat tire as far forward in
the trunk as possible. Store the jack
and wheel wrench in their
compartment in the trunk.
Storing
a jack, a tire or other
equipment in the passenger I
compartment of the vehicle could
cause injury.
In a sudden stop or I
collision, loose equipment could
strilce someone. Store all these
in
the proper place. I
The compact spare is for temporary use
only. Replace the compact spare tire
with a full-size tire as
soon as you can.

Compact Spare Tire
Although the compact spare 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 1tPa). The compact spare is
made to go up to 3,000 miles (5 000 lm),
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. Your anti-lock brake
system warning light may come on
when
you are driving with a compact
spare. See the
Index under Anti-Lock
Brake System Warning Light.

Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance
Services.
Use this rotation pattern.
If you don't have P245/50ZR16 size
tires, use the rotation pattern shown
above for your size tires.
256
If you have P245/510ZR16 size tires,
they must roll
in a certain 'direction for
the best overall performance. The
direction is shown
by an arrow on both
sidewalls. Because these tirles are
directional, they should be rotated
as
shown in the example above. These
tires should only be moved
from front
to rear and rear to front
on the same
side
of the vehicle.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown
on the Tire-Loading Information
label. Make certain that
all wheel nuts
are properly tightened. See the Index
under Wheel Nut Torque.
Rust or dirt on a wheel, or on
ri the parts to which it is
fastened, can make wheel nuts
become loose after a time. The
wheel could come off and cause an
accident. When you change a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency,
you
can use a cloth or a paper towel to
do this; but be sure to use a scraper
or wire brush later,
if you need to,
to get all the rust or dirt off. (See
the
Index under Changing a Flat
Tire.)

When It’s Time for New Tires
One way to tell when it’s time for new
tires is to check the treadwear
indicators, which will appear when your
tires have only
2/32 inch (1.6 mm) or
less
of tread remaining.
You need a new tire if:
You can see the indicators at three
You can see cord or fabric showing
The tread or sidewall is cracked, cut
places
around the tire.
through the tire’s rubber.
or snagged deep enough to show cord
or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other
damage that can’t
be repaired well
because
of the size or location of the
damage.
Buying New Tires
To find out what kind and size of tires
you need, look at the Tire-Loading
Information label. The tires installed on
your vehicle when it was new had a Tire
Performance Criteria Specification
(TPC Spec) number on each tire’s
sidewall. When
you get new tires, get
ones with that same
TPC Spec number.
That way, your vehicle will continue to
have tires that are designed to give
proper endurance, handling, speed
rating, traction, ride and other things
during normal service on your vehicle.
If your tires have an all-season tread
design, the
TPC number will be
followed by a
“MS” (for mud and
snow). If
you ever replace your tires with those
not having a
TPC Spec number, make
sure they are the same size, load range,
speed rating and construction type
(bias, bias-belted or radial) as your
original tires.
‘1 Mixing tires could cause you
A to lose control while driving.
If you mix tires
of different sizes or
types (radial and bias-belted tires),
the vehicle may not handle
properly, and you could have a
crash. Be sure to use the same size
and type tires on all wheels. It’s all
right to drive with your compact
spare, though. It was developed for
limited use on vour vehicle.

Using the wrong replacement I
1‘ I wheels, wheel bolts, or wheel

have a collision in which yau or
others could be injured. Always use
the correct wheel, wheel bolts, and
wheel nuts for replacement.
The wrong wheel can also cause

If your Pontiac has P215/60R16,
P225/60R16 or P245/50ZR16 size
tires, don’t use tire chains; they
can damage your vehicle.
If you have other tires,
use
chains only when you must. I
only SAE Class “S” type chains
that are the proper size for your
tires. Install them on the front til
and tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and
fnlh
the chain manufacturer’s
instructions. If you can hear
t
chains contacting your vehicle,
stop and retighten them.
If the
contact continues, slow
down until
it stops. Driving too fast with
chains on will damage your
vehicle.
