2007 CHEVROLET COLORADO spare tire

You may notice, during cooler weather conditions,
that the low tire pressure warning light and the
DIC LOW TIRE message may come on when the
vehicle is rst started, and then turn off as you
start to drive. This may be an early indicator
that the air pressure in the tire(s) is getting low
and needs to be inated to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire ination pressure label. (If your vehicle
has tires of a different size than the size indicated
on the vehicle placard or tire ination pressure
label, you should determine the proper tire
ination pressure for those tires.)As an added safety
feature, your vehicle has
been equipped with a
tire pressure monitoring
system (TPMS) that
illuminates a low tire
pressure telltale when
one or more of your
tires is signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inate them to the
proper pressure. Driving on a signicantly
under-inated tire causes the tire to overheat
and can lead to tire failure. Under-ination also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even
if under-ination has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 391
andWheel Replacement on page 396for
more information.
Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire.
If it moves, use the wheel wrench to tighten
the cable. SeeChanging a Flat Tire on page 400.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle.
The rst rotation is the most important, see
Scheduled Maintenance on page 442.When rotating your tires, always use one of the
correct rotation patterns shown here.
If your vehicle has a compact spare tire or a spare
tire that does not match your vehicle’s road tires
and wheels, in size and type, do not include
the spare in the tire rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label. For the
location of the Tire and Loading Information label
seeLoading Your Vehicle on page 293. Make
certain that all wheel nuts are properly tightened,
see “Wheel Nut Torque” underCapacities and
Specications on page 437for the proper wheel
nut torque specication.

CAUTION: (Continued)
Your vehicle may have a compact spare
tire and wheel assembly. If the vehicle
has a compact spare tire and wheel,
they have the same overall diameter
as your vehicle’s full-size tires and
wheels. Because they were designed
and developed for use on your vehicle,
it is all right to drive your vehicle with
the compact spare installed properly.
Compact spare tires are designed for
temporary use only. SeeSpare Tire
on page 420.
{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.
If you must replace your vehicle’s tires with
those that do not have a TPC Spec number,
make sure they are the same size, load range,
speed rating, and construction type (radial and
bias-belted tires) as your vehicle’s original tires.
Your vehicle’s original equipment tires are listed
on the Tire and Loading Information Label.
This label is attached to the vehicle’s center pillar
(B-pillar). SeeLoading Your Vehicle on page 293,
for more information about the Tire and Loading
Information Label and its location 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 (NHTSA),
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
(UTQG) 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 your vehicle has a at tire, use the following
example as a guide to assist you in the placement
of the 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 tools you will need are located under the
passenger’s seat.
For crew cab models, the jack and wheel blocks
are located under the driver’s side rear seat.
Crew Cab
401

For regular and
extended cab vehicles,
the jack and wheel
blocks are located
under the cover at the
center of the vehicle
behind the front seats.
To access the tools:
1. Move the seats
forward to access
the cover.2. Turn the wing nut on the cover
counterclockwise to remove it.
For crew cab models, reach under the rear
seat to access the jack and wheel blocks.
To reinstall the jack and wheel block assembly
in the mounting bracket, insert the tabs into
the jack base by pushing the blocks up into
the assembly. The outer hole in the jack base
aligns with the tab on the bracket. When
reinstalling, make sure the jack is secure, but
do not overtighten the jack in the bracket.
3. Remove the wheel blocks and the wheel
block retainer by turning the wing nut
counterclockwise.
4. Put the wheel blocks at the front and rear
of the tire farthest away from the one being
changed. That would be the tire on the
other side, at the opposite end of the vehicle.
5. Locate the wing nut used to retain the storage
bag and tools which is under the front
passenger’s seat. Remove it by turning the
wing nut counterclockwise.
You will use the jack handle extensions and the
wheel wrench to remove the underbody-mounted
spare tire.
