Notice:If the vehicle has
low‐profile tires, they are more
susceptible to damage from
road hazards or curb impact
than standard profile tires.
Tire and/or wheel assembly
damage can occur when
coming into contact with
road hazards like, potholes,
or sharp edged objects,
or when sliding into a curb.
The vehicle warranty does not
cover this type of damage.
Keep tires set to the correct
inflation pressure and, when
possible avoid contact with
curbs, potholes, and other
road hazards.
Tire Sidewall Labeling
Useful information about a
tire is molded into its sidewall.
The example below shows a
typical passenger (p‐metric)
tire sidewall.
Passenger (P‐Metric) Tire Example
(A) Tire Size:The tire size
is a combination of letters
and numbers used to define
a particular tire's width, height,
aspect ratio, construction type,
and service description. See the
“Tire Size” illustration later in this
section for more detail. (B) TPC Spec (Tire
Performance Criteria
Specification)
:Original
equipment tires designed to
GM's specific tire performance
criteria have a TPC specification
code molded onto the sidewall.
GM's TPC specifications meet
or exceed all federal safety
guidelines.
(C) DOT (Department
of Transportation)
:The
Department of Transportation
(DOT) code indicates that
the tire is in compliance
with the U.S. Department of
Transportation Motor Vehicle
Safety Standards.

the wheel in inches.
(F) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount
of air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in psi (pounds per
square inch) or kPa (kilopascal). Accessory Weight
:This
means the combined weight
of optional accessories.
Some examples of optional
accessories are, automatic
transmission, power steering,
power brakes, power windows,
power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.
Belt
:A rubber coated layer of
cords that is located between
the plies and the tread. Cords
may be made from steel or other
reinforcing materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim. Bias Ply Tire
:A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline
of the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in psi (pounds per
square inch) or kPa (kilopascal)
before a tire has built up heat
from driving. See Tire Pressure
on page 10‑66.
Curb Weight
:The weight of a
motor vehicle with standard and
optional equipment including
the maximum capacity of fuel,
oil, and coolant, but without

Vehicle Care 10-69
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.
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. TPMSmalfunctions 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. TPMS sensors
are mounted onto each tire and
wheel assembly on your vehicle.
The TPMS sensors monitor the air
pressure in the vehicle's tires and
transmits the 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, located
in the instrument panel cluster.

Vehicle Care 10-71
TPMS Malfunction Light and
Message
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 warning light flashes for
about one minute and then stays
on for the remainder of the ignition
cycle. A DIC warning message is
also displayed. The low tire warning
light and DIC warning message
come on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light and DIC message
to come on are:
.The TPMS sensor matching
process was not done or not
completed successfully. The DIC
message should go off after
successfully completing the
sensor matching process.
.One or more TPMS sensors
are missing or damaged. Under
these conditions the TPMS
malfunction light (low tire
warning light) comes on, and at
the same time the DIC message
is displayed. The DIC message
and TPMS malfunction light
should go off once the TPMS
sensors are installed and the
sensor matching process is
performed successfully.
.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 10‑73.
.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 and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate your vehicle's
tires, the identification 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 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.

10-72 Vehicle Care
Tire Inspection
We recommend that you
regularly inspect your 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.
Tire Rotation
The tires on your vehicle are
different sizes front to rear.
Due to this, the tires should
not be rotated. Each tire and
wheel should be used only in
the position it is in.
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.

10-74 Vehicle Care
GM's exclusive TPC Spec system
considers over a dozen critical
specifications 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 10‑61, 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. See Tire Inspection on
page 10‑72 andTire Rotation on
page 10‑72.{WARNING
Tires could explode during
improper service. You or others
could be injured or killed if you
attempt to mount or dismount
a tire. Only your dealer or an
authorized tire service center
should mount and dismount the
tires.
Winter tires with the same speed
rating as your original equipment
tires may not be available for H, V,
W, Y and ZR speed rated tires.
If you choose snow tires with a
lower speed rating, never exceed
the tire's maximum speed capability.
{WARNING
Mixing tires could cause you to
lose control while driving. If you
mix tires of different sizes (other
than those originally installed on
your vehicle), 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
(other than those originally
installed on your vehicle), brands
or types, may also cause damage
to your vehicle. Be sure to use
the correct size, brand, and type
tires on all four wheels.

Black plate (75,1)Chevrolet Corvette Owner Manual - 2011
Vehicle Care 10-75
{WARNING
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.
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.
Vehicles that have a tire pressure
monitoring system could give an
inaccurate low‐pressure warning
if non‐TPC Spec rated tires are
installed on it. 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.
See
Tire Pressure Monitor
Operation on page 10‑69.
Your vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑14,
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
could 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, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{WARNING
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 specific wheel and
tire systems developed for your
vehicle, and have them properly
installed by a GM certified
technician.
See Buying New Tires on
page 10‑73 andAccessories and
Modifications on page 10‑4 for
additional information.

Vehicle Care 10-77
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 specified 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.
Temperature –A, B, C
The temperature grades
are A (the highest), B, and C,
representing the tire's resistance
to the generation of heat and its
ability to dissipate heat when tested under controlled
conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life,
and excessive temperature
can lead to sudden tire failure.
The grade C corresponds to a
level of performance which all
passenger car tires must meet
under the Federal Motor Safety
Standard No. 109. Grades B
and A represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law. Warning: The
temperature grade for this tire
is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.Wheel Alignment and Tire
Balance
The tires and wheels on the vehicle
were aligned and balanced carefully
at the factory to give 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 there
is unusual tire wear or the vehicle
pulls to one side or the other, the
alignment should be checked. If the
vehicle vibrates when driving on a
smooth road, the tires and wheels
might need to be rebalanced. See
your dealer for proper diagnosis.

10-78 Vehicle Care
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 if any of these
conditions exist.
Your dealer 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 or wheel nuts,
replace them only with new GM
original equipment parts. This way,
you will be sure to have the right
wheel, wheel bolts, and wheel nuts
for your vehicle.
{WARNING
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.
{WARNING
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used or
how far it has been driven.
It could fail suddenly and cause
a crash. If you have to replace a
wheel, use a new GM original
equipment wheel.
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 clearance to
the body and chassis.

Black plate (79,1)Chevrolet Corvette Owner Manual - 2011
Vehicle Care 10-79
{WARNING
Rust or dirt on a wheel, or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. 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 you need to, to get all
the rust or dirt off.Tightening Wheel Lug Nuts
{WARNING
Never use oil or grease on studs
or the threads of the wheel nuts.
If you do, the wheel nuts might
come loose and the wheel could
fall off, causing a crash.
{WARNING
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead
to a crash. Be sure to use the
correct wheel nuts. If you have
to replace them, be sure to get
new GM original equipment
wheel nuts. Notice:
Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage.
To avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification.
Tighten the wheel lug nuts firmly in
a crisscross sequence as shown.
