2004 PONTIAC BONNEVILLE spare tire

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.

Removing the Flat Tire and Installing
the Spare Tire
1. Use the wheel wrench to loosen the wheel nuts, but
do not remove them.
2. The jack has a bolt at the end. Attach the wheel
wrench to the bolt to create a jack handle.3. Turn the wheel wrench counterclockwise to lower
the jack lift head until it ts under the vehicle.
5-83

{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.
5. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the compact
spare tire to t under the wheel well.
6. Remove all the wheel nuts and take off the at tire.
5-85

7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the 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
the 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.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
8. Place the compact spare tire on the wheel-mounting
surface.
9. Then reinstall the
wheel nuts with the
rounded end of
the nuts toward the
wheel.
Make sure each wheel bolt is centered in each wheel
hole while tightening the nuts. Tighten each nut by
hand until the wheel is held against the hub.
5-86

12. Do not try to put the wheel cover on the compact
spare tire. It will not t. Store the wheel cover in
the trunk until you have replaced the compact spare
tire with a regular tire.
Notice:Wheel covers will not t on your compact
spare. If you try to put a wheel cover on the compact
spare, you could damage the cover or the spare.
When you reinstall the full size wheel and tire, you install
the wheel cover or nut caps at this point.
When reinstalling the nut caps on aluminum wheels,
tighten the caps snug with the wheel wrench. Then
continue tightening one-quarter turn for plastic caps, or
one-eighth turn for steel caps. Do not overtighten.Storing the Flat Tire and Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
After you have put the compact spare tire on your
vehicle, you will need to store the at tire in your trunk.
Store the at tire as far forward in the trunk as
possible. Store the jack and wheel wrench in their
compartment in the trunk. For storage, the jack must be
raised until the screw end is ush with the edge of
the jack.

Compact Spare Tire
Although the compact spare tire was fully inated when
your vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure
your spare tire is correctly inated. 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 nish your trip and have your full-size
tire repaired or replaced where you want. You must
calibrate the Check Tire Pressure System after installing
or removing the compact spare. SeeCheck Tire
Pressure System on page 5-68. 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.Notice:When the compact spare is installed, don’t
take your vehicle through an automatic car wash
with guide rails. The compact spare can get caught
on the rails. That can damage the tire and wheel,
and maybe other parts of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t t. Keep your compact
spare tire and its wheel together.
Notice:Tire chains won’t t your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.
