Vehicle Care 10-49
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle. This
label shows the vehicle's
original equipment tires and the
correct inflation pressures for
the tires when they are cold. The recommended cold tire
inflation pressure, shown on the
label, is the minimum amount of
air pressure needed to support
the vehicle's maximum load
carrying capacity.
For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, see
Vehicle
Load Limits on page 9‑12. How
you load the vehicle affects
vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry. When to Check
Check the tires once a month or
more. Do not forget to check the
compact spare tire, if the vehicle
has one. The compact spare
should be at 420 kPa (60 psi).
For additional information
regarding the compact spare
tire, see
Compact Spare Tire on
page 10‑69.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
You cannot tell if the tires are
properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they are underinflated. Check
the tire's inflation pressure when
the tires are cold. Cold means
the vehicle has been sitting for
at least three hours or driven no
more than 1.6 km (1 mile).

Black plate (50,1)Chevrolet Aveo Owner Manual - 2011
10-50 Vehicle Care
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until you reach the
recommended amount.
If you overfill the tire, release
air by pushing on the metal stem
in the center of the tire valve.
Re‐check the tire pressure with
the tire gauge.
Be sure to put the valve caps
back on the valve stems. They
help prevent leaks by keeping
out dirt and moisture.Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation 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 tirepressure telltale when one or
more of your tires is significantly
under‐inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on
a significantly under‐inflated tire
causes the tire to overheat and can
lead to tire failure. Under‐inflation
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‐inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.

Black plate (51,1)Chevrolet Aveo Owner Manual - 2011
Vehicle Care 10-51
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash 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.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. If your vehicle has
this feature, the TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
your vehicle's tires and transmit tire
pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
on the instrument panel cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9‑12.
The low tire pressure warning light
comes on at each ignition cycle until
the tires are inflated to the correct
inflation pressure.

Black plate (52,1)Chevrolet Aveo Owner Manual - 2011
10-52 Vehicle Care
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
could be an early indicator that the
tire pressures are getting low and
need to be inflated to the proper
pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
SeeVehicle Load Limits on
page 9‑12, for an example of the tire
information label and its location on
your vehicle. Also see Tire Pressure
on page 10‑48. Your vehicle's TPMS system can
warn you about a low tire pressure
condition but it does not replace
normal tire maintenance. See
Tire
Inspection on page 10‑53, Tire
Rotation on page 10‑54, and Tires
on page 10‑42.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM-approved tire sealant
available through your dealer or
included in the vehicle.TPMS Malfunction Light
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. The malfunction
light comes on at each ignition cycle
until the problem is corrected. Some
of the conditions that can cause the
malfunction light to come on are:
.One of the road tires has been
replaced with the spare tire. The
spare tire does not have a
TPMS sensor. The malfunction
light should go off once you
re-install the road tire containing
the TPMS sensor and the
sensor matching process is
performed successfully.

Black plate (53,1)Chevrolet Aveo Owner Manual - 2011
Vehicle Care 10-53
.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the vehicle's tires. The
malfunction light should go off
after successfully completing the
sensor matching process.
.One or more TPMS sensors
are missing or damaged. The
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service.
.Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 10‑56.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction. If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer for
service if the TPMS malfunction
light comes on and stays on.
TPMS Sensor Identification
Codes
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors, or rotate the vehicle's tires,
the identification codes need to be
matched to the new tire/wheel
position. The sensors are matched,
to the tire/wheel positions, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer for service.
Tire Inspection
We recommend that you
regularly inspect the vehicle's
tires, including the spare tire,
if the vehicle has one, for signs
of wear or damage at least once
a month.
Always remove the 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.

10-54 Vehicle Care
Tire Rotation
Tires should be rotated every
12 000 km (7,500 miles). See
Scheduled Maintenance on
page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that your vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate your tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels. See
When It Is Time for New Tires
on page 10‑55andWheel
Replacement on page 10‑60 for
more information.
When rotating your tires, always
use the correct rotation pattern
shown here.
Do not include the compact
spare tire in the tire rotation.
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the tire and loading information
label. See Vehicle Load Limits
on page 9‑12 for an example of
the Tire and Loading Information
label and where it is located on
your vehicle. Make certain that all wheel nuts are properly
tightened. See
“Wheel Nut
Torque” underCapacities and
Specifications on page 12‑2.
See your dealer to reset the Tire
Pressure Monitor System
(TPMS) after rotating the tires,
if a tire pressure monitor
reception error occurs.
{WARNING
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
changing a wheel, remove any
rust or dirt from places where the
(Continued)

Vehicle Care 10-55
WARNING (Continued)
wheel attaches to the vehicle. In
an emergency, 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. SeeIf a Tire Goes Flat
on page 10‑61.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions influence 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 the
tires have only 1.6 mm (1/16 in) or
less of tread remaining. See TireInspection on page 10‑54
andTire
Rotation on page 10‑54 for
additional information.
The rubber in tires age over time.
This is also true for the spare tire,
if the vehicle has one, even if it is
not being used. Multiple conditions
affect how fast this aging takes
place, including temperatures,
loading conditions, and inflation
pressure maintenance. Tires will
typically need to be replaced due to
wear before they may need to be
replaced due to age. Consult the tire
manufacturer for more information
on when tires should be replaced.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park
a vehicle that will be stored for at
least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be
free of grease, gasoline, or other
substances that can deteriorate
rubber.

Black plate (56,1)Chevrolet Aveo Owner Manual - 2011
10-56 Vehicle Care
Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
Buying New Tires
GM has developed and matched
specific tires for the vehicle. If
you need replacement tires, GM
strongly recommends that you get
tires that are the same size, brand,
load range, speed rating, and
construction type (radial and
bias‐belted tires) as the vehicle's
original tires. This way, the vehicle
will continue to have tires that
are designed to give the same
performance and vehicle safety,
during normal use, as the original
tires. SeeTire Sidewall Labeling on
page 10‑42 for additional
information. GM recommends replacing tires in
sets of four. This is because uniform
tread depth on all tires will help
keep the 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 the vehicle. See
Tire
Inspection on page 10‑53 andTire
Rotation on page 10‑54.
{WARNING
Tires could explode during
improper service. Attempting to
mount or dismount a tire could
cause injury or death. Only your
dealer or authorized tire service
center should mount or dismount
the tires.
{CAUTION
Mixing tires could cause you
to lose control 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. It is
all right to drive with your
compact spare temporarily, as
it was developed for use on
your vehicle. See Compact
Spare Tire on page 10‑69.

Black plate (57,1)Chevrolet Aveo Owner Manual - 2011
Vehicle Care 10-57
{CAUTION
If you use bias-ply tires on the
vehicle, the wheel rim flanges
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.
Vehicles that have a tire pressure
monitoring system could give an
inaccurate low‐pressure warning if
tires not recommended for the
vehicle are installed. Tires that do
not match the original equipment
tires could give a low‐pressure
warning that is higher or lower than
the proper warning level you would
get with original equipment tires.
See Tire Pressure Monitor System
on page 10‑50. The vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑12,
for more information about the Tire
and Loading Information label and
its location on the vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are
a different size than the original
equipment wheels and tires, this
could affect the way the vehicle
performs, including its braking, ride
and handling characteristics,
stability, and resistance to rollover.
Additionally, if the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{WARNING
If different sized wheels are used,
there may not be an acceptable
level of performance and safety
if tires not recommended for
those wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
See Buying New Tires on
page 10‑56 andAccessories and
Modifications on page 10‑4 for
additional information.
Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width.
For example:

Black plate (58,1)Chevrolet Aveo Owner Manual - 2011
10-58 Vehicle Care
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 applyto 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.
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions
on a specified government test
course. For example, a tire
graded 150 would wear one and
a half (1½) 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 significantly from the
norm due to variations in
driving habits, service practices
and differences in road
characteristics and climate.
