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 0160.

246 Vehicle Care
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.
(Continued)
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 0254 for
inflation pressure adjustment for
high-speed driving.
All-Season Tires
This vehicle may come with
all-season tires. These tires are
designed to provide good overall
performance on most road surfaces
and weather conditions. Original
equipment tires designed to GM's
specific tire performance criteria
have a TPC specification code
molded onto the sidewall. Original
equipment all-season tires can be
identified by the last two characters
of this TPC code, which will
be “MS.”
Consider installing winter tires on
the vehicle if frequent driving on
snow or ice-covered roads is
expected. All-season tires provide
adequate performance for most
winter driving conditions, but they
may not offer the same level of
traction or performance as winter
tires on snow or ice-covered roads.
See Winter Tires 0247.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
Vehicle Care 247
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, seeBuying New Tires 0261.
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
(Continued)
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) when carrying a
load of driver plus one passenger.
When carrying a heavier load, total
distance driven without air should
be reduced. As soon as possible,
contact the nearest authorized GM
or run-flat servicing facility for
inspection and repair or
replacement.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
248 Vehicle Care
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.
Low-Profile Tires
Low-Profile Performance TiresCaution
If the vehicle has 245/
35ZR19 and 305/30ZR20 size
tires, they are classified as
low-profile performance tires.
Low-profile tires are more
susceptible to damage from road (Continued)
Caution (Continued)
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
when possible, avoid contact with
curbs, potholes, and other road
hazards.
Summer Tires
High Performance Summer Tires
This vehicle may come with 245/
35ZR19 and 305/30ZR20 high
performance summer tires. These
tires have a special tread and
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 Tires
0247.
Caution
High performance summer 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 high
performance summer 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 5 °C (40 °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. SeeTire
Inspection 0259.
Tire Sidewall Labeling
Useful information about a tire is
molded into its sidewall. The
example shows a typical
passenger tire sidewall.
Passenger (P-Metric) Tire Example
(1) 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.
(2) 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.
(3) 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.
DOT Tire Date of
Manufacture
:The last four
digits of the TIN indicate the tire
manufactured date. 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.
(4) Tire Identification Number
(TIN)
:The letters and numbers
following the DOT code are the
Tire Identification Number (TIN).
