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. See Vehicle Load
Limits 0177.
(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.

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 0272 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 0278.
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

Warning (Continued)
drive over 80 km/h (50 mph) when
the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.
Run-flat tires can be driven on with
no air pressure. 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. To prevent permanent
damage, the tire can be driven with
no air pressure for up to 80 km
(50 mi) at speeds slower than
80 km/h (50 mph). 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 while deflated, 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 Customer
Assistance.
The valve stems on run-flat tires
have sensors that are part of the
TPMS. See
Tire Pressure Monitor
System 0273. These sensors
contain batteries that are designed
to last for 10 years under normal
driving conditions. See your dealer
for wheel or sensor replacement.
Caution
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.
Caution
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 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 (Continued)

when possible, avoid contact with
curbs, potholes, and other road
hazards.
Competition Oriented
Tires
This vehicle may come with P285/
30ZR19 and P335/25ZR20 Michelin
PS CUP2 competition oriented tires
that are DOT approved for street
use. Competition oriented tires use
a special tread pattern 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 pattern and compound
will have decreased performance in
cold climates, heavy rain, and
standing water. It is recommended
that winter tires be installed on the
vehicle when driving at
temperatures below approximately10 °C (50 °F) or on ice or snow
covered roads. See
Winter
Tires 0263.
{Warning
Driving on wet roads, in heavy
rain, or through standing water
with competition oriented tires
may cause hydroplaning and loss
of control. Use extreme caution
and drive slowly on wet roads.
{Warning
Driving with competition oriented
tires on snow, ice, or cold road
surfaces can cause loss of control
or an accident. Competition
oriented tires are 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
competition oriented tires in these
conditions.
Caution
Competition oriented tires have
rubber compounds that lose
flexibility and may develop
surface cracks in the tread area
at temperatures below −7 °C
(20 °F). Always store competition
oriented tires indoors and at
temperatures above −7 °C (20 °F)
when not in use. If the tires have
been subjected to −7 °C (20 °F) or
less, let them warm up in a
heated space to at least 10 °C
(50 °F) for 24 hours or more
before being installed or driving a
vehicle on which they are
installed. Do not apply heat or
blow heated air directly on the
tires. Always inspect tires before
use. See Tire Inspection 0275.
Summer Tires
High Performance Summer Tires
This vehicle may come with high
performance summer tires. These
tires have a special tread and

9956103) - 2017 - crc - 4/28/16
266 Vehicle Care
compound that are optimized for
maximum dry and wet road
performance. This special tread and
compound will have decreased
performance in cold climates, and
on ice and snow. It is recommended
that winter tires be installed on the
vehicle if frequent driving at
temperatures below approximately
5 °C (40 °F) or on ice or snow
covered roads is expected. See
Winter Tires0263.
Caution
High performance summer tires
have rubber compounds that lose
flexibility and may develop
surface cracks in the tread area

Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9956103) - 2017 - crc - 4/28/16
Vehicle Care 271
Caution
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.
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.
On rare occasions, vehicles with
P245/40ZR18 and P285/35ZR19
size tires may experience a
rough ride at the tire pressure
recommended on the Tire and
Loading Information label. To
improve ride performance,
decrease the tire pressure to no
less than 205 kPa (30 psi) when
the tire is cold. This may reduce
fuel economy and cause the low
tire pressure warning to occur
more often.
Inflate the tires to the
recommended pressure once
rough ride road conditions have
passed. 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 0177. 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).

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9956103) - 2017 - crc - 4/28/16
272 Vehicle Care
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.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would
not be covered by the vehicle
warranty.Tire Pressure for
High-Speed Operation
{Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
This could cause 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 allow the vehicle
to be driven at high speeds, make
sure the tires are rated for
high-speed operation, are in
excellent condition, and are 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 160 km/h (100 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 0177.
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.

9956103) - 2017 - crc - 4/28/16
Vehicle Care 273
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 tire
pressure 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.
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.
