Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer.
See the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{WARNING
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a result
of too much flexing. There
could be a blowout and a
serious crash. SeeVehicle
Load Limits on page 9‑14.
(Continued)
WARNING (Continued)
.Underinflated tires pose the
same danger as overloaded
tires. The resulting crash
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when the
tires are cold.
.Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact—such as when
hitting a pothole. Keep tires at
the recommended pressure.
.Worn or old tires can cause a
crash. If the tread is badly
worn, replace them.
.Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
(Continued)
WARNING (Continued)
.Improperly repaired tires can
cause a crash. Only the
dealer or an authorized tire
service center should repair,
replace, dismount, and mount
the tires.
.Do not spin the tires in
excess of 55 km/h (35 mph)
on slippery surfaces such
as snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.
SeeTire Pressure for
High-Speed Operation on
page 10‑68 for inflation pressure
adjustment for high-speed
driving.

Vehicle Care 10-59
Winter Tires
Consider installing winter tires on
the vehicle if frequent driving on
snow or ice covered roads is
expected. All season tires provide
good overall performance on most
surfaces, but they may not offer
the traction or the same level of
performance as winter tires on
snow or ice covered roads.
Winter tires, in general, are
designed for increased traction
on snow and ice covered roads.
With winter tires, there may be
decreased dry road traction,
increased road noise, and shorter
tread life. After changing to winter
tires, be alert for changes in vehicle
handling and braking.See your dealer for details
regarding winter tire availability and
proper tire selection. Also, see
Buying New Tires on page 10‑74.
If using snow tires:
.Use tires of the same brand and
tread type on all four wheel
positions.
.Use only radial ply tires of the
same size, load range, and
speed rating as the original
equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
Run-Flat Tires
This vehicle, when new, had run-flat
tires. There is no spare tire, no tire
changing equipment, and no place
to store a tire in the vehicle.
The vehicle also has a Tire
Pressure Monitor System (TPMS)
that indicates a loss of tire pressure
in any of the tires.
{WARNING
If the low tire warning light
displays on the instrument panel
cluster, the handling capabilities
will be reduced during severe
maneuvers. Driving too fast could
cause loss of control and you or
others could be injured. Do not
drive over 90 km/h (55 mph)
when the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.

Black plate (60,1)Chevrolet Corvette Owner Manual - 2012
10-60 Vehicle Care
If a tire goes flat, there is no need to
stop on the side of the road to
change the tire. Continue driving,
however, do not drive too far or too
fast. Driving on the tire may not be
possible if there is permanent
damage. The tire can be driven with
no air pressure for up to 105 km
(65 miles) at speeds slower than
90 km/h (55 mph). The shorter the
distance and the slower the speed,
the greater the chance the tire will
not have to be replaced. As soon as
possible, contact the nearest
authorized GM or run-flat servicing
facility for inspection and repair or
replacement. When driving on a
deflated run-flat tire, avoid potholes
and other road hazards that could
damage the tire and/or wheel
beyond repair. When a tire has been
damaged, or if driven any distance
on a deflated run-flat tire, check with
an authorized run-flat tire service
center to determine whether the
tire can be repaired or should be
replaced. To maintain the run-flat
feature, all replacement tires must
be run-flat tires.To locate the nearest GM or run-flat
servicing facility, call Roadside
Assistance. See
Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10 for details.
The valve stems on run-flat tires
have sensors that are part of the
TPMS. See Tire Pressure Monitor
System on page 10‑68. These
sensors contain batteries that are
designed to last for 10 years
under normal driving conditions.
See your dealer for wheel or sensor
replacement.
Notice: Using liquid sealants can
damage the tire valves and tire
pressure monitor sensors in the
run-flat tires. This damage is not
covered by the vehicle warranty.
Do not use liquid sealants in
run-flat tires.Low-Profile Tires
Low‐Profile Performance Tire
The original equipment tires on
this vehicle are classified as
low‐profile performance tires.
These tires are designed for
very responsive driving on wet
or dry pavement, however, may
produce more road noise and
tend to wear faster.
Notice: Low‐profile tires 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

Black plate (61,1)Chevrolet Corvette Owner Manual - 2012
Vehicle Care 10-61
objects, or when sliding into a
curb. The 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.Sport Cup Tires
This vehicle may come with
Michelin Pilot Sport Cup competition
oriented tires that are DOT approved
for street use. These tires are
included on the Z06 model with
the Z07 Performance Package and
on the ZR1 model with the PDE
High Performance Package.
Sport Cup tires use a special tread
and compound that provide more
grip than normal road tires.
The minimum tread depth will be
reached earlier than typical tires,
resulting in reduced tire life.
This special tread and compound
will decrease performance in cold
climates, heavy rain, and standing
water.{WARNING
Driving on wet roads, in heavy
rain, or through standing water
with Sport Cup tires may cause
hydroplaning and loss of control.
Use extreme caution and drive
slowly on wet roads.
{WARNING
Driving with Sport Cup tires on
snow, ice, or cold road surfaces
can cause loss of control or an
accident. Sport Cup tires are a
summer season tires and are not
intended to be driven on snow,
ice, or road surfaces below
10° C (50° F). Do not drive a
vehicle with Sport Cup tires in
these conditions.

Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.
Notice: Neither tire
underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.

Black plate (67,1)Chevrolet Corvette Owner Manual - 2012
Vehicle Care 10-67
Overinflated tires, or tires
that have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading
Information label on the
vehicle indicates the original
equipment tires and the correct
cold tire inflation pressures.
The recommended pressure is
the minimum 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 9‑14.
How the vehicle is loaded
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.
How to Check
Use a good quality pocket-type
gauge to check the tire
pressure. Proper tire inflation
cannot be determined by looking
at the tire. Check the tire
inflation pressure when the tires
are cold, meaning the vehicle
has not been driven for at least
three hours or no more than
1.6 km (1 mi). Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get the 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 the recommended
pressure is reached. If the
inflation pressure in high, press
on the metal stem in the center
of the tire valve to release air.
Re‐check the tire pressure with
the tire gauge.
Return the valve caps on the
valve stems to keep out dirt and
moisture and prevent leaks.

Tire Pressure for
High-Speed Operation
{WARNING
Driving at high speeds, 160 km/h
(100 mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
inflation pressure adjustment for
high-speed operation. When
speed limits and road conditions
are such that a vehicle can be
driven at high speeds, make sure
the tires are rated for high-speed
operation, in excellent condition,
and set to the correct cold tire
inflation pressure for the
vehicle load.The tires require inflation pressure
adjustment when driving the vehicle
at speeds of 282 km/h (175 mph) or
higher, where it is legal. Set the cold
inflation pressure to the maximum
inflation pressure shown on the
tire sidewall, or 265 kPa (38 psi),
whichever is lower. See the
example following. Return the tires
to the recommended cold tire
inflation pressure when high-speed
driving has ended. See
Vehicle
Load Limits on page 9‑14.
Example:
The maximum load and inflation
pressure molded on the tire
sidewall, in small letters, near the
rim flange. It will read something
like this: Maximum load 690 kg
(1521 lbs) 300 kPa (44 psi)
Max. Press.
For this example, set the inflation
pressure for high‐speed driving at
265 kPa (38 psi). Racing or other competitive driving
may affect the warranty coverage
of the vehicle. See the warranty
booklet for more information.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.)
