Recommended Fuel 0227.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have
enacted laws regarding driver distraction.
Become familiar with the local laws in
your area.
To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a phone in demanding driving
situations. Use a hands-free method to
place or receive necessary phone calls.

Warning (Continued)
.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 0287 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.
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 Tires0280.
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 0294.
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, may have had
run-flat tires. There is no spare tire, no tire
changing equipment, and no place to store a
tire in the vehicle.
{Warning
While driving with run-flat tires at a
reduced inflation pressure, avoid making
sudden stops or severe maneuvers as the
handling capabilities of the tires will be
reduced. Driving too fast could cause loss
of control and you or others could be
injured. Do not drive over 80 km/h
(50 mph) with the tire operating at low
pressure. Drive cautiously and check the
tire pressure as soon as possible.
Run-flat tires can be driven up to 80 km
(50 mi) at speeds less than 80 km/h
(50 mph) after a loss of inflation pressure
has occurred. There is no need to stop on
the side of the road to change the tire. The
possible driving range after a pressure loss
will vary based on the vehicle load and
driving conditions. 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-
17272984) - 2024 - CRC - 2/20/23
Vehicle Care 281
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
If the vehicle has 245/35ZR19,
305/30ZR20, 275/30ZR20, or 345/25ZR21
size tires, they are classified as
low-profile tires.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
(Continued)
Caution (Continued)
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.
Competition Oriented Tires
This vehicle may come with 275/30ZR20 and
345/25ZR21, Michelin Pilot Sport Cup 2 R ZP,
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 approximately 10 °C (50 °F) or on ice
or snow covered roads.
{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 a crash. 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).

290 Vehicle Care
The low tire pressure warning light may
come on in cool weather when the vehicle is
first started, and then turn off as the vehicle
is driven. This could be an early indicator
that the air pressure is getting low and
needs to be inflated to the proper pressure.
A Tire and Loading Information label shows
the size of the original equipment tires and
the correct inflation pressure for the tires
when they are cold. SeeVehicle Load Limits
0 174, for an example of the Tire and
Loading Information label and its location.
Also see Tire Pressure 0286.
The TPMS can warn about a low tire
pressure condition but it does not replace
normal tire maintenance. See Tire Inspection
0 291, Tire Rotation 0292, and Tires0279.
Caution
Tire sealant materials are not all the
same. A non-approved tire sealant could
damage the TPMS sensors. TPMS sensor
damage caused by using an incorrect tire
sealant is not covered by the vehicle
warranty. Always use only the GM
approved tire sealant available through
your dealer or included in the vehicle.
TPMS Malfunction Light and Message
The TPMS will not function properly if one
or more of the TPMS sensors are missing or
inoperable. When the system detects a
malfunction, the low tire pressure warning
light 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:
.One of the road tires has been replaced
with the spare tire. The spare tire does
not have a TPMS sensor. The malfunction
light and the DIC message should go off
after the road tire is replaced and the
sensor matching process is performed
successfully. See "TPMS Sensor Matching
Process" later in this section.
.The TPMS sensor matching process was
not done or not completed successfully
after rotating the tires. The malfunction
light and the DIC message should go off
after successfully completing the sensor
matching process. See "TPMS Sensor
Matching Process" later in this section.
.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. See your dealer for service.
.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 0294.
.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 stay on.
Tire Fill Alert (If Equipped)
This feature provides visual and audible
alerts outside the vehicle to help when
inflating an underinflated tire to the
recommended cold tire pressure.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
292 Vehicle Care
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.
.The tire has a bump, bulge, or split.
.The tire has a puncture, cut, or other
damage that cannot be repaired well
because of the size or location of the
damage.
Tire Rotation
Tires should be rotated according to the
interval listed in the maintenance
schedule. SeeMaintenance Schedule
0 316.
Tires are rotated to achieve uniform
wear for all tires. The first rotation is
the most important.
Anytime unusual wear is noticed, rotate
the tires as soon as possible, check for
proper tire inflation pressure, and check for damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel alignment.
See
When It Is Time for New Tires
0 293 and
Wheel Replacement 0297.
Different tire sizes should not be
rotated front to rear.
Use this rotation pattern if the vehicle
has different size tires on the front
and rear. Caution
Wheels will become scratched if not
handled properly. When laying a tire and
wheel assembly flat on the ground, place
it face up with a towel underneath it.
Move the assembly by rolling it on the
tires. Do not drag it.
Adjust the front and rear tires to the
recommended inflation pressure on the
Tire and Loading Information label after
the tires have been rotated. See
Tire
Pressure 0286 and
Vehicle Load Limits 0174.
Reset the Tire Pressure Monitor System.
See Tire Pressure Monitor Operation
0 289.
Check that all wheel nuts are properly
tightened. See “Wheel Nut Torque”
under Capacities and Specifications
0 325.

294 Vehicle Care
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 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 MS for mud and snow. SeeTire
Sidewall Labeling 0282 for additional
information. GM recommends replacing worn tires in
complete sets of four. Uniform tread
depth on all tires will help to maintain
the performance of the vehicle. Braking
and handling performance may be
adversely affected if all the tires are not
replaced at the same time. If proper
rotation and maintenance have been
done, all four tires should wear out at
about the same time. However, if it is
necessary to replace only one axle set
of worn tires, place the new tires on
the rear axle. See
Tire Rotation0292.
{Warning
Tires could explode during improper
service. Attempting to mount or
dismount a tire could cause injury or
death. Only your dealer or authorized
tire service center should mount or
dismount the tires.
{Warning
Mixing tires of different sizes (other
than those originally installed on the
vehicle), brands, tread patterns,
or types may cause loss of vehicle
control, resulting in a crash or other
vehicle damage. Use the correct size,
brand, and type of tire on all wheels.
{Warning
Using bias-ply tires on the vehicle
may cause the wheel rim flanges to
develop cracks after many miles of
driving. A tire and/or wheel could fail
suddenly and cause a crash. Use only
radial-ply tires with the wheels on
the vehicle.
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. Never exceed the
winter tires’ maximum speed capability
when using winter tires with a lower
speed rating.
