2007 CHEVROLET COLORADO tires

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will ash for approximately
one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.A Tire and Loading Information label, attached
to your vehicle, shows the size of your vehicle’s
original equipment tires and the correct ination
pressure for your vehicle’s tires when they
are cold. SeeLoading Your Vehicle on page 293,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also seeInation - Tire Pressure on page 384
for additional information.
Your vehicle’s TPMS can warn you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection
and Rotation on page 390,When It Is Time for
New Tires on page 391, andTires on page 377.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The
liquid sealant can damage the tire pressure
monitor sensors.

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate your vehicle’s tires,
the identication codes will need to be matched
to the new tire/wheel position. The sensors
are matched to the tire/wheel positions in the
following order: driver’s side front tire, passenger’s
side front tire, passenger’s side rear tire, and
driver’s side rear tire using a TPMS diagnostic
tool. See your dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. If increasing the tire’s
air pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You will have one minute to match the rst
tire/wheel position, and ve minutes overall, to
match all four tire/wheel positions. If it takes
longer than one minute, to match the rst tire
and wheel, or more than ve minutes to match
all four tire and wheel positions the matching
process stops and you will need to start over.The TPMS sensor matching procedure is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Turn the exterior lamp switch from AUTO
to OFF four times within three seconds.
A double horn chirp will sound and the TPMS
low tire warning light starts ashing. The
double horn chirp and ashing TPMS warning
light indicates the TPMS matching process
has started. The TPMS warning light should
continue ashing throughout the matching
procedure. The LOW TIRE message displays
on the Driver Information Center (DIC).
4. Start with the driver’s side front tire.
5. Remove the valve cap from the valve cap
stem. Activate the TPMS sensor by increasing
or decreasing the tire’s air pressure for
10 seconds, then stop and listen for a single
horn chirp. The single horn chirp should sound
within 15 seconds, conrming that the sensor
identication code has been matched to this
tire and wheel position. If you do not hear the
conrming single horn chirp, turn the ignition
switch to LOCK and start over beginning with
388

Step 2. To let air-pressure out of a tire you
can use the pointed end of the valve cap,
a pencil-style air pressure gage, or a key.
6. Proceed to the passenger’s side front tire,
and repeat the procedure in Step 5.
7. Proceed to the passenger’s side rear tire,
and repeat the procedure in Step 5.
8. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 5.
9. After hearing the conrming horn chirp for the
driver side rear tire, check to see if the TPMS
low tire warning light and the DIC LOW TIRE
messages have turned off. If yes, the TPMS
sensors have been relearned. Turn the ignition
switch to LOCK.
If the low tire warning light and the DIC SERV
TPM messages are on after completing Step 5
for the driver side rear tire, the sensor relearn
process has not been successful. Turn the
ignition switch to LOCK and repeat the
matching process beginning with Step 2.
10. Set all four tires to the recommended air
pressure level as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the valve stems.Federal Communications

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.
390

{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 400.
Any time you rotate the vehicle’s tires the Tire
Pressure Monitor System (TPMS) will need to be
reset. The TPMS identication codes will need
to be matched to the tire and wheel position.
See “TPMS Sensor Identication Codes” under
Tire Pressure Monitor System on page 385.
When It Is Time for New Tires
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
Some commercial truck
tires may not have
treadwear indicators.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
The tread or sidewall is cracked, cut 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 cannot be repaired well because of the
size or location of the damage.
391

Buying New Tires
GM has developed and matched specic tires
for your vehicle. The original equipment tires
installed on your vehicle, when it was new,
were designed to meet General Motors Tire
Performance Criteria Specication (TPC spec)
system rating. If you need replacement tires,
GM strongly recommends that you get tires
with the same TPC Spec rating. This way,
your vehicle will continue to have tires that
are designed to give the same performance
and vehicle safety, during normal use, as the
original tires.
GM’s exclusive TPC Spec system considers over
a dozen critical specications that impact the
overall performance of your vehicle, including
brake system performance, ride and handling,
traction control, and tire pressure monitoring
performance. GM’s TPC Spec number is molded
onto the tire’s sidewall by the tire manufacturer.
If the tires have an all-season tread design,
the TPC spec number will be followed by an MS
for mud and snow. SeeTire Sidewall Labeling
on page 378for additional information.{CAUTION:
Mixing tires could cause you to lose
control of your vehicle while driving.
If you mix tires of different sizes, brands,
or types (radial and bias-belted tires),
the vehicle may not handle properly, and
you could have a crash. Using tires of
different sizes, brands, or types may also
cause damage to your vehicle. Be sure
to use the correct size, brand, and type
of tires on all wheels.
CAUTION: (Continued)
392

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.

Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires, this
may affect the way your vehicle performs, including
its braking, ride and handling characteristics,
stability, and resistance to rollover. Additionally,
if your vehicle has electronic systems such as,
anti-lock brakes, traction control, and electronic
stability control, the performance of these systems
can be affected.{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires
not recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
GM certied technician.
