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.(Continued)
Warning (Continued)
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 0350
and Accessories and
Modifications 0308.
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.
Quality grades can be
found where applicable on
the tire sidewall between
tread shoulder and
maximum section width.
For example:

2023 - CRC - 2/23/22
Vehicle Care 353
Treadwear 200 Traction AA
Temperature A
All Passenger Car Tires
Must Conform to Federal
Safety Requirements In
Addition To These Grades.
Treadwear
The treadwear grade is a
comparative rating based
on the wear rate of the tire
when tested under
controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one
and one-half (1½) times as
well on the government
course as a tire graded
100. The relative
performance of tires
depends upon the actual
conditions of their use,
however, and may depart
significantly from the norm
due to variations in drivinghabits, service practices
and differences in road
characteristics and climate.
Traction
The traction grades, from
highest to lowest, are AA,
A, B, and C. Those grades
represent the tire's ability
to stop on wet pavement
as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C
may have poor traction
performance. Warning: The
traction grade assigned to
this tire is based on
straight-ahead braking
traction tests, and does not
include acceleration,
cornering, hydroplaning,
or peak traction
characteristics.
Temperature
The temperature grades
are A (the highest), B, and
C, representing the tire's
resistance to the
generation of heat and its
ability to dissipate heat
when tested under
controlled conditions on a
specified indoor laboratory
test wheel. Sustained high
temperature can cause the
material of the tire to
degenerate and reduce tire
life, and excessive
temperature can lead to
sudden tire failure. The
grade C corresponds to a
level of performance which
all passenger car tires must
meet under the Federal
Motor Safety Standard
No. 109. Grades B and A
represent higher levels of
performance on the
laboratory test wheel than
the minimum required by

Cadillac Lyriq Owner Manual (GMNA-Localizing-U.S./Canada-15644413) -
2023 - CRC - 2/23/22
354 Vehicle Care
law. Warning: The
temperature grade for this
tire is established for a tire
that is properly inflated and
not overloaded. Excessive
speed, underinflation,
or excessive loading, either
separately or in
combination, can cause
heat buildup and possible
tire failure.
Wheel Alignment and
Tire Balance
The tires and wheels were
aligned and balanced at the
factory to provide the longest
tire life and best overall
performance. Adjustments to
wheel alignment and tire
balancing are not necessary
on a regular basis. Consider an
alignment check if there is
unusual tire wear or the
vehicle is significantly pulling
to one side or the other. Some
slight pull to the left or right,
depending on the crown of theroad and/or other road
surface variations such as
troughs or ruts, is normal.
If the vehicle is vibrating when
driving on a smooth road, the
tires and wheels may need to
be rebalanced. See your
dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is
bent, cracked, or badly rusted
or corroded. If wheel nuts
keep coming loose, the wheel,
wheel bolts, and wheel nuts
should be replaced. If the
wheel leaks air, replace it.
Some aluminum wheels can be
repaired. See your dealer if
any of these conditions exist.
Your dealer will know the kind
of wheel that is needed.
Each new wheel should have
the same load-carrying
capacity, diameter, width,
offset, and be mounted the
same way as the one it
replaces.
Replace wheels, wheel bolts,
wheel nuts, or Tire Pressure
Monitor System (TPMS)
sensors with new GM original
equipment parts.
{Warning
Using the wrong
replacement wheels, wheel
bolts, or wheel nuts can be
dangerous. It could affect
the braking and handling of
the vehicle. Tires can lose air
and cause loss of control,
resulting in a crash. Always
use the correct wheel, wheel
bolts, and wheel nuts for
replacement.
{Warning
Replacing a wheel with a
used one is dangerous. How
it has been used or how far
it has been driven may be
unknown. It could fail
suddenly and cause a crash.

Vehicle Care 355
Warning (Continued)
When replacing wheels, use
a new GM original
equipment wheel.
Caution
The wrong wheel can also
cause problems with bearing
life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle
ground clearance, and tire or
tire chain clearance to the
body and chassis.
Tire Chains
Caution
If the vehicle is equipped
with tire size 265/50R20,
use tire winter traction
devices only where legal and
only when necessary. Only
use textile traction devices,(Continued)
Caution (Continued)
such as tire snow socks,
that are the proper size for
the tires. Traction devices
must be installed only on the
tires of the drive axle. Drive
slowly and follow the
traction device
manufacturer’s instructions.
Driving too fast or spinning
the wheels can damage the
traction device.
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. See Tires
0334 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 self-sealing
tires, see Self-Sealing Tires
0
336. Tread punctures
typically will not cause tires to
lose air. However, if the vehicle
does get a flat tire, there is no
spare tire, tire changing
equipment, or place to store a
tire. Contact Roadside Service
0 388 for help.

356 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 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 0145.

If hand sanitizer comes in
contact with interior
surfaces of the vehicle,
blot immediately and clean
with a soft cloth
dampened with a mild
soap and water solution.
Interior Glass
To clean, use a microfiber
cloth fabric dampened with
water. Wipe droplets left
behind with a clean dry cloth.
If necessary, use a commercial
glass cleaner after cleaning
with plain water.
Caution
To prevent scratching, never
use abrasive cleaners on
automotive glass. Abrasive
cleaners or aggressive
cleaning may damage the
rear window defogger.
Cleaning the windshield with
water during the first three to
six months of ownership will
reduce tendency to fog.
Speaker Covers

appearance and feel of the
vinyl/rubber and can make
the floor slippery. Your foot
could slip while operating
the vehicle, and you could
lose control, resulting in a
crash. You or others could
be injured.
Fabric/Carpet/Suede
Start by vacuuming the
surface using a soft brush
attachment. If a rotating
vacuum brush attachment is
being used, only use it on the
floor carpet. Before cleaning,
gently remove as much of the
soil as possible:
.Gently blot liquids with a
paper towel. Continue
blotting until no more soil
can be removed.
.For solid soils, remove as
much as possible prior to
vacuuming.To clean:
1. Saturate a clean, lint-free colorfast cloth with water.
Microfiber cloth is
recommended to prevent
lint transfer to the fabric or
carpet.
2. Remove excess moisture by gently wringing until water
does not drip from the
cleaning cloth.
3. Start on the outside edge of the soil and gently rub
toward the center. Fold the
cleaning cloth to a clean
area frequently to prevent
forcing the soil into the
fabric.
4. Continue gently rubbing the soiled area until there is no
longer any color transfer
from the soil to the cleaning
cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by
plain water. If the soil is not completely
removed, it may be necessary
to use a commercial
upholstery cleaner or spot
lifter. Test a small hidden area
for colorfastness before using
a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the
entire fabric or carpet.
After cleaning, use a paper
towel to blot excess moisture.
Cleaning High Gloss
Surfaces and Vehicle
Information and Radio
Displays
Use a microfiber cloth on high
gloss surfaces or vehicle
displays. First, use a soft
bristle brush to remove dirt
that can scratch the surface.
Then gently clean by rubbing
with a microfiber cloth. Never
use window cleaners or
solvents. Periodically hand
wash the microfiber cloth
separately, using mild soap. Do

{Warning
Do not bleach or dye seat
belt webbing. It may severely
weaken the webbing. In a
crash, they might not be
able to provide adequate
protection. Clean and rinse
seat belt webbing only with
mild soap and lukewarm
water. Allow the webbing
to dry.
Floor Mats
{Warning
If a floor mat is the wrong
size or is not properly
installed, it can interfere
with the pedals. Interference
with the pedals can cause
unintended acceleration
and/or increased stopping
distance which can cause a
crash and injury. Make sure
the floor mat does not
interfere with the pedals.Use the following guidelines
for proper floor mat use:
.The original equipment floor
mats are designed for your
vehicle. If the floor mats
need to be replaced, it is
recommended that
GM-certified floor mats are
purchased. Non-GM floor
mats may not fit properly
and may interfere with the
pedals. Always check that
the floor mats do not
interfere with the pedals.
.Do not use a floor mat if the
vehicle is not equipped with
a floor mat retainer on the
driver side floor.
.Use the floor mat with the
correct side up. Do not turn
it over.
.Do not place anything on top
of the driver side floor mat.
.Use only a single floor mat
on the driver side.
.Do not place one floor mat
on top of another.
Removing and Replacing
the Floor Mats
The driver side floor mat is
held in place by two
button-type retainers.
The passenger side floor mat
is held in place by two
button-type retainers.
1. Pull up on the rear of the
floor mat to unlock each
retainer and remove.
2. Reinstall by lining up the floor mat retainer openings
over the carpet retainers
and snapping into position.
