2005 GMC JIMMY spare tire

Buying New Tires
To nd out what kind and size of tires you need, look at
the Tire and Loading Information label. For more
information about this label and its location on your
vehicle, SeeLoading Your Vehicle on page 4-44.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specication (TPC Spec)
number on each tire’s sidewall. When you get new tires,
GM recommends that you get tires 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 an “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.{CAUTION:
Mixing tires could cause you 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. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels. It’s all right to drive with your
compact spare (if you have one). It was
developed for use on your vehicle.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.

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.

When you have a at tire, use the following example as a
guide to assist you in the placement of wheel blocks.
The following information will tell you next how to use
the jack and change a tire.
Removing the Spare Tire and Tools
The jacking equipment you’ll need is stored along
the driver’s side inner rear quarter panel. In some cases,
you may have to remove the spare tire in order to
reach the jack.The following instructions explain how to remove the
spare tire, depending on where it is mounted on
your vehicle. SeeSpare Tire on page 5-80.
1. Remove your jack cover by pulling up on the
latch(es) on the cover (C). Remove the wheel
blocks (D), jack (G) and wheel wrench (F).
Notice:If you remove or restow a tire from/to the
storage position under the vehicle when it is
supported by a jack, you could damage the tire
and/or your vehicle. Always remove or restow a tire
when the vehicle is on the ground.

2. Remove the
underbody-mounted
spare by inserting the
chisel end of the wheel
wrench, on an angle,
into the hoist shaft hole
in the rear bumper.
Be sure the chisel end
of the wheel wrench
connects into the
hoist shaft.
3. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench until
the spare tire has been completely lowered.
4. Tilt the retainer at the end of the cable and pull it
through the wheel opening.
5. Pull the tire out from under the vehicle.
Notice:If you drive away before the spare tire
cable has been reinstalled, you could damage your
vehicle. Always reinstall this cable before driving
your vehicle.
If you have an inside-mounted spare tire, the tire must be
removed in order to have access to the jack storage.To remove an inside-mounted spare tire, reach into your
tire’s cover and unscrew the wing nut at the center of
the wheel. Remove it and the retainer. Unhook the
tire from the mounting bracket and remove the cover.
To remove a rear-mounted spare tire, rst make
sure that the carrier arm is fully-latched to the tailgate.
Then remove the spare tire cover.
If you have this feature,
the locking wheel nut can
be removed by snapping
the rubber weather
cover off the face of the
lock case.
5-69

Insert the key and pull the
lock case straight off. It is
not necessary to turn
the key.
Put the spare tire near the at tire.
The tools you’ll be using include the jack (A) and wheel
wrench (B). Your vehicle may also have an optional
hub cap removal tool.
5-70

Removing the Flat Tire and
Installing the Spare Tire
Position the chisel end of your wheel wrench, or the hub
cap removal tool (if equipped), in the notch of the hub
cap and pry off the hub cap.
Some of the molded plastic hub caps have imitation
wheel nuts molded into them. The wheel wrench won’t
t these imitation nuts, so don’t try to remove them
with the socket end of the wheel wrench.If you have individual wheel nut caps that cover each
nut, they must be removed in order to get to the wheel
nuts. Use the socket end of the wheel wrench to
remove the wheel nut caps.
Your wheel nut caps may attach your hub cap to the
wheel. Remove these wheel nut caps before you take off
the hub cap.

{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{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.4. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare tire to
t underneath the wheel well.
5. Remove all the wheel nuts and take off the at tire.
5-73

10. Use the wrench to
tighten the wheel nuts
rmly in a crisscross
sequence as shown.
Storing a Flat or Spare Tire
and Tools
Store the at tire in the same location as
your spare tire.
{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.
Notice:An aluminum wheel with a at tire should
always be stored under the vehicle with the
hoist. However, storing it that way for an extended
period could damage the wheel. To avoid this,
have the tire repaired as soon as possible.
