tire pressure CHEVROLET COLORADO 2009 1.G Owner's Manual

When rotating your tires, always use the correct
rotation pattern shown here.
Do not include the spare or compact spare tire 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. SeeInflation - Tire
Pressure on page 5-63andLoading the Vehicle on
page 4-33.
Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-67.Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-117.
{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 5-80.
Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire.
If it moves, tighten the cable. SeeStoring a Flat
or Spare Tire and Tools on page 5-95.

When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions,
inuence when you need new tires.
One way to tell when it
is time for new tires is to
check the treadwear
indicators, which 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 new tires 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.
The rubber in tires degrades over time, even if they are
not being used. This is also true for the spare tire, if your
vehicle has one. Multiple conditions affect how fast this
aging takes place, including temperatures, loading
conditions, and ination pressure maintenance. With
proper care and maintenance tires will typically wear out
before they degrade due to age. If you are unsure about
the need to replace your tires as they get older, consult
the tire manufacturer for more information.
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.
5-72

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 near the
tire size. 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 5-57
for additional information.
GM recommends replacing tires in sets of four. This is
because uniform tread depth on all tires will help keep
your vehicle performing most like it did when the tires
were new. Replacing less than a full set of tires can affect
the braking and handling performance of your vehicle.
SeeTire Inspection and Rotation on page 5-70for
information on proper tire rotation.
{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,
CAUTION: (Continued)
CAUTION: (Continued)
or types may also cause damage to your vehicle.
Be sure to use the correct size, brand, and type of
tires on all wheels.
Your vehicle may have a compact spare tire and
wheel assembly. It is all right to drive with your
vehicle’s compact spare tire temporarily. It was
developed for use on your vehicle. SeeSpare Tire
on page 5-100.
{CAUTION:
If you use bias-ply tires on the 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 the
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.
5-73

Vehicles that have a tire pressure monitoring system
could give an inaccurate low-pressure warning if
non-TPC Spec rated tires are installed on your vehicle.
Non-TPC Spec rated tires may give a low-pressure
warning that is higher or lower than the proper warning
level you would get with TPC Spec rated tires.
SeeTire Pressure Monitor System on page 5-65.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information Label. SeeLoading the
Vehicle on page 4-33, 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, antilock 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.
SeeBuying New Tires on page 5-72andAccessories
and Modifications on page 5-3for additional information.
5-74

Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and
balanced carefully at the factory to give you the longest
tire life and best overall performance. Adjustments to
wheel alignment and tire balancing will not be necessary
on a regular basis. However, if you notice unusual tire
wear or your vehicle pulling to one side or the other, the
alignment might need to be checked. If you notice your
vehicle vibrating when driving on a smooth road, the tires
and wheels might need to be rebalanced. See your
dealer/retailer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts, and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer/retailer if any of these conditions exist.
Your dealer/retailer will know the kind of wheel
you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset, and be mounted
the same way as the one it replaces.If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, wheel nuts, and TPMS sensors
for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel bolts,
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts, and wheel nuts for
replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-80for more
information.

Spare Tire
Compact Spare Tire
Your vehicle may have a compact spare tire. Although
the compact spare tire was fully inated when your
vehicle was new, it can lose air over time. Check the
ination pressure regularly. It should be 60 psi (420 kPa).
Notice:If the vehicle has four-wheel drive and the
compact spare tire is installed on the vehicle, do not
drive in four-wheel drive until you can have the at
tire repaired and/or replaced. You could damage the
vehicle, and the repair costs would not be covered by
your warranty. Never use four-wheel drive when the
compact spare tire is installed on the vehicle.
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
vehicle’s spare tire is correctly inated. The compact
spare is made to perform well at speeds up to 62 mph
(100 km/h) for distances up to 500 miles (804 km).
For heavy payloads or towing, and for low traction or
four-wheel-drive conditions, repair or replace the full-size
tire. Of course, it is best to replace your vehicle’s spare
with a full-size tire as soon as you can. The spare tire
will last longer and be in good shape in case you need
it again.Notice:When the compact spare is installed, do not
take the vehicle through an automatic car wash with
guide rails. The compact spare can get caught on the
rails which can damage the tire, wheel and other
parts of the vehicle.
Do not use your compact spare on other vehicles.
And do not mix your compact spare tire or wheel
with other wheels or tires. They will not t. Keep
your spare tire and its wheel together.
Notice:Tire chains will not t the compact spare.
Using them can damage the vehicle and can damage
the chains too. Do not use tire chains on the
compact spare.
Full-Size Spare Tire
Your vehicle may have a full-size spare tire, which,
when new, was fully inated. A spare tire may lose air
over time, so check its ination pressure regularly. See
Inflation - Tire Pressure on page 5-63andLoading the
Vehicle on page 4-33for information regarding proper tire
ination and loading your vehicle. For instruction on how
to remove, install, or store a spare tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-85and
