Tire Terminology and
Denitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight
:This means
the combined weight of optional
accessories. Some examples of
optional accessories are,
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire’s height to its width.
Belt
:A rubber coated layer of
cords that is located between the
plies and the tread. Cords
may be made from steel or other
reinforcing materials.Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire
:A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in pounds per square
inch (psi) or kilopascals (kPa)
before a tire has built up heat
from driving. SeeInflation - Tire
Pressure on page 9-46.
Curb Weight
:The weight of a
motor vehicle with standard
and optional equipment including
the maximum capacity of fuel,
oil, and coolant, but without
passengers and cargo.DOT Markings
:A code
molded into the sidewall of a
tire signifying that the tire
is in compliance with the
U.S. Department of
Transportation (DOT) motor
vehicle safety standards.
The DOT code includes the Tire
Identication Number (TIN),
an alphanumeric designator
which can also identify the tire
manufacturer, production
plant, brand, and date of
production.
GVWR
:Gross Vehicle Weight
Rating. SeeLoading the Vehicle

Tire Chains
{CAUTION
Do not use tire chains. There is
not enough clearance. Tire
chains used on a vehicle
without the proper amount of
clearance can cause damage to
the brakes, suspension or other
vehicle parts. The area
damaged by the tire chains
could cause you to lose control
of the vehicle and you or others
may be injured in a crash.
(Continued)
CAUTION (Continued)
Use another type of traction
device only if its manufacturer
recommends it for use on the
vehicle and tire size
combination and road
conditions. Follow that
manufacturer’s instructions. To
help avoid damage to the
vehicle, drive slowly, readjust
or remove the device if it is
contacting the vehicle, and do
not spin the vehicle’s wheels. If
you do nd traction devices
that will t, install them on the
front tires.
Tire Changing
If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain your tires properly. See
Tires on page 9-39. If air goes out
of a tire, It is much more likely
to leak out slowly. But if you should
ever have a blowout, here are a
few tips about what to expect
and what to do:
If a front tire fails, the at tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip the
steering wheel rmly. Steer to
maintain lane position, and then
gently brake to a stop well out of the
traffic lane.
9-62 Vehicle Service and Care
2008 - Pontiac G8 Owner Manual

A rear blowout, particularly on a
curve, acts much like a skid
and may require the same correction
you would use in a skid. In any
rear blowout, remove your foot from
the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It
may be very bumpy and noisy,
but you can still steer. Gently brake
to a stop, well off the road if
possible.
If a tire goes at, and your vehicle
has a compact spare tire, see
Changing a Flat Tire (V6 Engine) on
page 9-71. This information shows
you how to use the vehicle’s
tire changing equipment and how to
change a at tire safely.{CAUTION
Lifting a vehicle and getting
under it to do maintenance or
repairs is dangerous without the
appropriate safety equipment
and training. The jack provided
with your vehicle is designed
only for changing a at tire. If it
is used for anything else, you or
others could be badly injured or
killed if the vehicle slips off the
jack. Use the jack provided with
your vehicle only for changing a
at tire.
Tire Sealant and
Compressor Kit
If your vehicle has a factory installed
Tire Sealant and Compressor kit,
there is no spare tire, no tire
changing equipment and no place to
store a tire.If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place and stopping.
1. Turn on the hazard warning
ashers. SeeHazard Warning
Flashers on page 4-4.
2. Park your vehicle. Set the
parking brake rmly and put the
shift lever in PARK (P). See
Shifting Into Park (Automatic
Transmission) on page 8-10.
3. Turn off the engine.
4. Inspect the at tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a puncture larger than a
14inch (6 mm), the tire is too
severely damaged for the tire
sealant and compressor kit to be
effective. SeeRoadside Assistance
Program on page 12-6.
If the tire has a puncture less than a
14inch (6 mm) in the tread area
of the tire, seeTire Sealant
and Compressor Kit (V8 Engine) on
page 9-64.

Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you will want to
get to know your rig. Acquaint
yourself with the feel of handling and
braking with the added weight of the
trailer. And always keep in mind that
the vehicle you are driving is now a
good deal longer and not nearly as
responsive as your vehicle is by
itself.
Before you start, check all trailer
hitch parts and attachments, safety
chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has electric brakes,
start your vehicle and trailer moving
and then apply the trailer brake
controller by hand to be sure
the brakes are working. This lets
you check your electrical connection
at the same time.
During your trip, check occasionally
to be sure that the load is secure,
and that the lamps and any
trailer brakes are still working.
Towing with the Electronic
Stability Program (ESP®)
When towing, the sound of the ESP
modulator might be heard. The
ESP is reacting to the vehicle
movement caused by the trailer,
which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as when driving
your vehicle without a trailer. This
can help avoid situations that require
heavy braking and sudden turns.
Passing
More passing distance is needed up
ahead when you are towing a
trailer. And, because the vehicle is
longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, just move
that hand to the left. To move the
trailer to the right, move the hand to
the right. Always back up slowly
and, if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. Your vehicle could
be damaged. Avoid making
very sharp turns while trailering.
When you are turning with a
trailer, make wider turns than
normal. Do this so your trailer will
not strike soft shoulders, curbs, road
signs, trees or other objects.
Avoid jerky or sudden maneuvers.
Signal well in advance.
