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 9-49.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 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 9-42. 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.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 on page 9-75.
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. If a
jack is provided with the vehicle, it
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. If a jack is provided
with the vehicle, only use it for
changing a at tire.

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. The 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.
