from the coolant boiling through overheating
and be ing pushed out of the cool ing system.
.&_ WARNING

Glossary of tire and loading
terminology
Accessory weight
means the combined weight ( in
excess of those standard items
which may be replaced) of auto­ matic transmission , power steer ­
ing, power brakes, power win­
dows, power seats, radio, and
heater, to the extent that these
items a re available as factory- in­
stalled equipment (whether i n­
stalled or not) .
Aspect ratio
means the ratio of the height to
the width of the tire in percent .
Numbers of 55 or lower indicate a
low s idewall for improved steer­
ing response and better overall
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead .
Wheel s
Cord
means the strands forming the
plies in the tire .
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manufac ­
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted .
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
cluding the maximum capacity of
fuel, oil , and coolant, air condi­
tioning and additional weight of
optional eq uipm ent .
Extra load tire

vehicle's Gross Veh ic le Weig ht
R ati ng
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs . (68 kg) for each passen­
ger at a designated seating posi ­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gro ss Ax le W eight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
T he fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen -
344
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rat ing
are listed on the safety compli­
ance sticker labe l located on the
driver's side B-pillar.
1.8. WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss
of contro l and a crash.
-Always make sure that the to­ tal load being transported
