2005 CADILLAC SRX 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 Spare Tire and Tools
The equipment you will need is located in the rear
of the vehicle. To access the equipment, do the
following:
1. Remove the storage bin to access the jack if your
vehicle has the cargo management system.
If your vehicle has the third row seat, remove the
head rest storage tray to access the jack.
2. Turn the wing nut (A) holding the jack (B) (and
storage tray, if applicable) counterclockwise and
remove it.
3. Remove the jack and wheel wrench (C).
Removing the Spare Tire
The compact spare tire is located under the vehicle,
ahead of the rear bumper. SeeCompact Spare Tire on
page 5-84for more information about the compact spare.
To remove the spare tire from the vehicle, do the
following:
A. Wheel Wrench
B. Cable
C. Retainer
D. Compact Spare Tire
1. Open the liftgate. SeeLiftgate on page 2-12for
more information.
2. Open the storage compartment door of the cargo
management system that is nearest the liftgate
and remove the container.
5-71

3. Attach the wheel wrench (A) into the hoist shaft.
4. Turn the wheel wrench counterclockwise to
lower the spare tire to the ground. Continue turning
the wrench until the spare tire (D) can be pulled
out from under the vehicle.5. Tilt the retainer (C) and slip it through the wheel
opening to remove the spare tire from the cable (B).
6. Turn the wrench clockwise until you feel two slips
or hear two clicks after removing the spare tire to
raise the cable back up.
Do not store a full-size or a at road tire under the
vehicle. SeeStoring a Flat or Spare Tire and
Tools on page 5-81.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-73.
If the spare tire will not lower, the secondary latch may
be engaged causing the tire not to lower.
5-72

Do the following to check the cable:
1. Check under the
vehicle to see if the
cable is visible. If it is
not visible, see
Secondary Latch
System on page 5-79.
2. If it is visible, rst try to tighten the cable by turning
the wheel wrench clockwise until you hear two
clicks or feel it skip twice. You cannot over-tighten
the cable.
3. Loosen the cable then by turning the wrench
counterclockwise three or four turns.
4. Tighten the cable all the way and then loosen it at
least two times, if the spare tire has not lowered.
If the spare tire did lower to the ground, continue
with Step 4 underRemoving the Spare Tire
and Tools on page 5-71.
If you still cannot lower the spare tire to the ground, see
Secondary Latch System on page 5-79.Removing the Flat Tire and
Installing the Spare Tire
To remove the at tire and install the spare, do the
following:
1. Using the at end of the wheel wrench, pry off the
center cap at the notch. Be careful; the edges may
be sharp. Don’t try to remove the cover with
your bare hands.

{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.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.5. Turn the wheel wrench clockwise to raise the jack
lift head until the jack just ts under the vehicle.
6. Raise the jack by turning the wheel wrench
clockwise until the slots in the jack head t into the
metal ange located behind the triangle on the
plastic molding as shown.
Notice:Using a jack to raise the vehicle without
positioning it correctly could damage your vehicle.
When raising your vehicle on a jack, be sure to
position it correctly under the frame and avoid
contact with the plastic molding.
7. Put the compact spare tire near you.
5-75

8. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to t under the
vehicle.9. Remove all the wheel
nuts and take off the
at tire.
{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.
5-76

{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.
10. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
11. Install the spare tire and put the wheel nuts back on
with the rounded end of the nuts toward the wheel.
12. Tighten each nut by hand until the wheel is
held against the hub.13. Lower the vehicle by attaching the wheel wrench to
the jack and turning the wrench counterclockwise.
Lower the jack completely.
5-77

{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come 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 new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-103for wheel nut
torque specication.
Notice: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
torque specication.14. Tighten the wheel nuts
rmly in a crisscross
sequence, as shown.
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.
15. Don’t try to put a wheel cover on the compact spare
tire. It won’t t. Store the wheel cover securely in
the rear of the vehicle until you have the at
tire repaired or replaced.
