(E) Rim Diameter:Diameter of
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
passengers and cargo.

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.

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.

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.

Tire Chains
{WARNING
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by
the tire chains could cause
you to lose control of the vehicle
and you or others may be injured
in a crash. Use another type
of traction device only if its(Continued)
WARNING (Continued)
manufacturer recommends it for
use on the vehicle and tire size
combination and road conditions.
Follow that manufacturer's
instructions. To help avoid
damage to the vehicle, drive
slowly, re‐adjust or remove the
device if it is contacting the
vehicle, and do not spin the
wheels. If you do find traction
devices that will fit, install them
on the rear tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while you are driving, especially if
you maintain the tires properly. If air
goes out of a tire, it is much more
likely to leak out slowly. See Tires
on page 10‑58 for additional
information. But if you should ever
have a blowout, here are a few tips
about what to expect and what
to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip
the steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
Black plate (81,1)Chevrolet Corvette Owner Manual - 2011
Vehicle Care 10-81
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction
you would use in a skid. In any rear
blowout remove your foot from the
accelerator pedal. Get the vehicle
under control by steering the way
you want the vehicle to go. It may
be very bumpy and noisy, but you
can still steer. Gently brake to a
stop, well off the road, if possible.
The vehicle has no spare tire, no
tire changing equipment, and no
place to store a tire.The vehicle, when new, had run-flat
tires. This type of tire can operate
effectively with no air pressure, so
you will not need to stop on the side
of the road to change a flat tire.
You can just keep on driving. The
shorter the distance you drive and
the slower the speed, the greater
the chance that the run-flat tire will
not have to be replaced. Run-flat
tires perform so well without any air
that a Tire Pressure Monitor System
(TPMS) is used to alert you if a tire
has lost pressure. See
Run-Flat
Tires on page 10‑59 andTire
Pressure Monitor System on
page 10‑68.{WARNING
Special tools and procedures
are required to service a run-flat
tire. If these special tools and
procedures are not used you
or others could be injured and
the vehicle could be damaged.
Always be sure the proper tools
and procedures, as described in
the service manual, are used.

Jump Starting
For more information about the
vehicle battery, seeBattery on
page 10‑43.
If your battery has run down, you
may want to use another vehicle
and some jumper cables to start
your vehicle. Be sure to use the
following steps to do it safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you. Notice:
If you try to start your
vehicle by pushing or pulling it,
you could damage your vehicle.
Do not push or pull your vehicle
to start it; instead, use the jump
starting procedure in this manual
to start your vehicle when the
battery has run down.
1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. Get the vehicles close enough so the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they
are, it could cause a ground
connection you do not want. You would not be able to start
your vehicle, and the bad
grounding could damage the
electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking
brakes.
Notice: If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle.
