Wheel s
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 are available as factory-in­
stalled equipment (whether in­
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 sidewall 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.
20 4
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the t ire 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 w ith standard equipment in­
cluding the maximum capacity of
fuel, oil, and coolant, ai r condi­
tioning and additional weight of
optional equipment.
E x tra load ti re
means a tire designed to operate
at higher loads and at higher in­
flation pressures than the corre­
sponding standard tire. Extra load
tires may be identified as "X L",
"
l" "EXTRA LOAD" or "RF" on X I I
the sidewall. .,.

Wheels
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially
loaded ¢ table
on page 213 .
If driving the vehi­
cle when fully loaded, you must
increase the tire pressure to the
maximum specified
pressure ¢.&. -
Checking/correcting tire
pressure
~check the tire pressure at least
once per month and also check it
before every long drive .
~Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
~check the label¢ fig . 188 for
the correct tire pressure based
on vehicle load.
~correct the tire pressure if nec­
essary .
~store the new tire pressure in
the Infotainment system
¢ page 220.
~check the pressure in the emer­
gency tire*/spare tire*. Always
maintain the maximum temper­
ature that is specified for the
tire.
212
& WARNING
Always adapt the tire pressure
to your driving style and vehicle
load .
-Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions
in¢ page 214,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
{tfj) Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.

Wheels
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("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-
214
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
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The 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
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 Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar.
