Curve Tips
.Ta k e c u r v e s a t a r e a s o n a b l espeed.
.Reduce speed before entering acurve.
.Maintain a reasonable steadyspeed through the curve.
.Wait until the vehicle is out ofthe curve before acceleratinggently into the straightaway.
Steering in Emergencies
.There are some situations whensteering around a problem maybe more effective than braking.
.Holding both sides of thesteering wheel allows you to turn180 degrees without removingahand.
.The Antilock Brake System(ABS) allows steering whilebraking.
Off-Road Recovery
The vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving. Followthese tips:
1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so that itstraddles the edge of thepavement.
2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.
3. Turn the steering wheel to gostraight down the roadway.
Loss of Control
Skidding
There are three types of skids thatcorrespond to the vehicle's threecontrol systems:
.Braking Skid—wheels are notrolling.
.Steering or Cornering Skid—too much speed or steering in acurve causes tires to slip andlose cornering force.
.Acceleration Skid—too muchthrottle causes the drivingwheels to spin.
Defensive drivers avoid most skidsby taking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.
If the vehicle starts to slide, followthese suggestions:
.Ease your foot off theaccelerator pedal and steer theway you want the vehicle to go.

Rear Axle
Axles must have 885 km (500 mi)before being used in track driving
The rear axle fluid temperaturesmay be higher when driving insevere conditions. Drain and refillwith new fluid after the first racing orcompetitive driving event, and thenafter every 24 hours of racing orcompetitive driving. SeeRecommended Fluids andLubricants0358.
Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear axle
and would not be covered by the
vehicle warranty. Do not drive as
long or as fast the first time the
vehicle is driven on the track or
raced.
For extended track use, GMrecommends installing a reardifferential cooler to protect therear axle.
Wheel Alignment
For racing and competitive driving,the vehicle load should be limited tothe driver only and no cargo. Thetires should be inflated cold to atleast 250 kPa (36 psi).
Caution
Using these wheel alignment
settings may cause excessive tire
wear. Only use these wheel
alignment settings for racing or
competitive driving. Excessive tire
wear is not covered under the
vehicle warranty.

Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this

304 Vehicle Care
Winter Tires
This vehicle was not originallyequipped with winter tires. Wintertires are designed for increasedtraction on snow and ice-coveredroads. Consider installing wintertires on the vehicle if frequentdriving on ice or snow coveredroads is expected. See your dealerfor details regarding winter tireavailability and proper tire selection.Also, seeBuying New Tires0317.
With winter tires, there may bedecreased dry road traction,increased road noise, and shortertread life. After changing to wintertires, be alert for changes in vehiclehandling and braking.
If using winter tires:
.Use tires of the same brand andtread type on all four wheelpositions.
.Use only radial ply tires of thesame size, load range, andspeed rating as the originalequipment tires.
Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.
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
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
Ultra High Performance SummerTires
This vehicle may come with 245/40R19 and 275/35R19 ultra highperformance summer tires. Thesetires have a special tread andcompound that are optimized formaximum dry and wet roadperformance. This special tread andcompound will have decreasedperformance in cold climates, andon ice and snow. Driving a vehiclewith ultra high performance summertires when temperatures are belowapproximately 5 °C (40 °F) is notrecommended. If driving in theseconditions, winter tires should beinstalled. SeeWinter Tires0304.
Caution
Ultra 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 °

Caution (Continued)
F). Always store ultra 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
Inspection0315.
Tire Sidewall Labeling
Useful information about a tire is
molded into its sidewall. The
examples show 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 for more detail.
(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).
The TIN shows the
manufacturer and plant code,

Chevrolet SS Sedan Owner Manual (GMNA-Localizing-U.S.-10122752) -2017 - crc - 8/31/16
306 Vehicle Care
tire size, and date the tire was
manufactured. The TIN is
molded onto both sides of the
tire, although only one side may
have the date of manufacture.
(5) Tire Ply Material:The type
of cord and number of plies in
the sidewall and under the tread.
(6) Uniform Tire Quality
Grading (UTQG):Tire
manufacturers are required to
grade tires based on three
performance factors: treadwear,
traction, and temperature
resistance. For more information
seeUniform Tire Quality
Grading0319.
(7) Maximum Cold Inflation
Load Limit:Maximum load that
can be carried and the
maximum pressure needed to
support that load.
Tire Designations
Tire Size
The following is an example of a
typical passenger vehicle
tire size.
(1) Passenger (P-Metric) Tire:
The United States version of a
metric tire sizing system. The
letter P as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item 3 of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(4) Construction Code:Aletter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.

310 Vehicle Care
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. See
Vehicle Load Limits0226.
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).
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.

Chevrolet SS Sedan Owner Manual (GMNA-Localizing-U.S.-10122752) -2017 - crc - 8/31/16
318 Vehicle Care
on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H,
V, W, a n d Z R s p e e d r a t e d t i r e s .
Never exceed the winter tire's
maximum speed capability when
using winter tires with a lower
speed rating.
{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,
or types may cause loss of
control of the vehicle, resulting in
acrashorothervehicledamage.
Use the correct size, brand, and
type of tire on all four wheels.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
Atireand/orwheelcouldfail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
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
Operation0312.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. SeeVehicle Load Limits
0226.
Different Size Tires and
Wheels
If wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, traction
