tains the recommended tire pressures for cold
tires on afully loaded vehicle and for the maxi-
mum permissible vehicle speed.
The tire pressure table contains the recommen-
ded pressures for cold tires for various operat-
ing conditions, i.e. differingl oad and speed con-
ditions.

equipment
The combined weight of all standard and
optional equipment available for the vehicle,
regardless of whether it is actually installed on
the vehicle or not.
Rim
This is the part of the wheel on which the tire is
mounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The gross
axle weight ratin gcan be found on the vehicle
identification plate on the B-pillar on the driver's
side.
Speed rating
The speed ratin gispart of the tire identification.
It specifies the speed range for which the tire is
approved.
GVW (Gross Vehicle Weight)

applicable). The gross vehicle weight ratin gis
specified on the vehicle identification plate on
the B-pillar on the driver'ss ide.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)

sponds to1psi. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index
In addition to the load-bearin gindex ,the load
index may also be imprinted on the sidewall of
the tire. This specifies the load-bearin gcapacity
more precisely.
Curb weight
The weight of avehicle with standard equipment
includin gthe maximum capacityoff uel, oil and
coolant .Italso includes the air-conditionin gsys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage.
