Warning (Continued)
.Replace any tires that
have been damaged by
impacts with potholes,
curbs, etc.
.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 56 km/h
(35 mph) on slippery
surfaces such as snow,
mud, ice, etc. Excessive
spinning may cause the
tires to explode.
See Tire Pressure for
High-Speed Operation 0264 for
inflation pressure adjustment for
high-speed driving.
Winter Tires
This vehicle was not originally
equipped with winter tires. Winter
tires are designed for increased
traction on snow and ice-covered
roads. Consider installing winter
tires on the vehicle if frequent
driving on ice or snow covered
roads is expected. See your dealer
for details regarding winter tire
availability and proper tire selection.
Also, see Buying New Tires 0269.
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.
If using winter 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 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

flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message also displays. The
malfunction light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause these to come on are:
.The TPMS sensor matching
process was not done or not
completed successfully. The
malfunction light and the DIC
message should go off after
successfully completing the
sensor matching process.
. One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully.
. Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended could prevent the TPMS from
functioning properly. See
Buying
New Tires 0269.
. 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
properly, it cannot detect or signal a
low tire pressure condition. See
your dealer for service if the TPMS
malfunction light and DIC message
come on and stays on.
TPMS Sensor Matching
Process —Auto Learn
Function
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. When a tire is
installed, the vehicle must be
stationary for about 20 minutes
before the system recalculates. The
following relearn process takes up
to 10 minutes, driving at a minimum speed of 19 km/h (12 mph).
A dash (-) or pressure value will
display in the DIC. See
Driver
Information Center (DIC) 0116.
A warning message displays in the
DIC if a problem occurs during the
relearn process.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is 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.

grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)or less of tread remaining.
See
Tire Inspection 0267 andTire
Rotation 0268.
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. GM recommends that
tires, including the spare if
equipped, be replaced after six
years, regardless of tread wear. The
tire manufacture date is the last four
digits of the DOT Tire Identification
Number (TIN) which is molded into
one side of the tire sidewall. The
first two digits represent the week
(01–52) and the last two digits, the
year. For example, the third week of
the year 2010 would have a
four-digit DOT date of 0310.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.
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. The
original equipment tires installed
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same TPC
Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11374030) - 2018 - crc - 3/29/17
Vehicle Care 271
load range, speed rating, and
construction (radial) as the
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.
SeeTire Pressure Monitor
Operation 0265.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. See Vehicle Load Limits
0 170.
Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also 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 0269 and
Accessories and Modifications
0 213.
Uniform Tire Quality
Grading
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 apply
to deep tread, winter tires,
compact 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.

control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive
slowly and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the rear tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. If air goes
out of a tire, it is much more likely to
leak out slowly. SeeTires0254 for
additional information. But if there
ever is 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.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. 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.
If the vehicle has run-flat tires, there
is no need to stop on the side of the
road to change a flat tire. See
Run-Flat Tires
0255.
{Warning
Special tools and procedures are
required to service a run-flat tire.
If these special tools and
(Continued)
Warning (Continued)
procedures are not used, injury or
vehicle damage may occur.
Always be sure the proper tools
and procedures, as described in
the service manual, are used.
If this vehicle does not have run-flat
tires and a tire goes flat, avoid
further tire and wheel damage by
driving slowly to a level place, well
off the road, if possible. Turn on the
hazard warning flashers. See
Hazard Warning Flashers 0138.
1. Turn on the hazard warning flashers.
2. Set the parking brake firmly.
3. Put an automatic transmission in P (Park) or a manual
transmission in 1 (First) or
R (Reverse).
4. Turn off the ignition.
5. Inspect the flat tire.

276 Vehicle Care
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
If this vehicle has a tire sealant kit
and the tire has been separated
from the wheel, has damaged
sidewalls, or has a puncture larger
than 6 mm (0.25 in), the tire is too
severely damaged for the tire
sealant and compressor kit to be
effective. If the tire has a puncture
less than 6 mm (0.25 in) in the tread
area of the tire, see Tire Sealant
and Compressor Kit 0276.
Tire Sealant and
Compressor Kit
{Warning
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains carbon monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, see Engine
Exhaust 0181.
{Warning
Overinflating a tire could cause
the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire sealant
and compressor kit instructions
and inflate the tire to its
(Continued)
Warning (Continued)
recommended pressure. Do not
exceed the recommended
pressure.
{Warning
Storing the tire sealant and
compressor kit or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store the tire
sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire or tire changing
equipment, and on some vehicles
there may not be a place to store
a tire.
To obtain a tire sealant and
compressor kit, see your dealer.

Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle
and removing the jumper cables,
allow it to idle for several minutes.
The power windows may need to be
initialized. See“Window Indexing”
under Power Windows 045.Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to
suspension components. Use the
proper straps around the tires to
secure the vehicle.
Use only a flatbed tow truck for
towing a disabled vehicle. Never
use a sling type lift or damage will
occur. Use ramps to help reduce
approach angles if necessary.
A towed vehicle should have its
drive wheels off the ground. Consult
a professional towing service if the
disabled vehicle must be towed.
Caution
Improper use of the tow eye can
cause vehicle damage. Use
caution and low speeds to
prevent damage to the vehicle.
If the vehicle is equipped with tow
eye, only use the tow eye to pull the
vehicle onto a flatbed car carrier
from a flat road surface. Do not use
the tow eye to pull the vehicle from
snow, mud or sand.
The tow eye is located underneath
the load floor, near the spare tire or
the compressor kit, if equipped.
