Maintenance and care

Uniform Tir eQ ualit yG rading StandardsAu nifor ms tandard to grade the quality of tires
with regards to tread quality, tire traction and
temperature characteristics. The quality grad-
ing assessmen tism ade by the manufacturer
following specification sf rom the U.S .g overn-
ment .T he ratings are molded int ot he sidewall of
the tire.
Recommended tir ep re ssuresThe recommended tire pressure applies to the
tires mounted at the factory.
The Tire and Loading Information placard con-
tains the recommended tire pressures for cold
tires on af ully 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. differin gl oad and speed con-
ditions.
Increased vehicle weight due to optional
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 gc an be found on the vehicle
identification plate on the B-pillar on the driver's
side.
Speed rating
The speed ratin gisp art of the tire identification.
It specifies the speed range for which the tire is
approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight of
the vehicle includin gf uel, tools, the spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight ,ifa pplicable. The gross
vehicle weight must not exceed the gross vehi-
cle weight ratin gG VWR as specified on the vehi-
cle identification plate on the B-pillar on the
driver' ss ide. GVW R( Gross Vehicle Weight Rating)The GVWR is the maximum permissible gross
weight of af ully loaded vehicle (the weight of the
vehicle includin ga ll accessories, occupants,
fuel, luggage and the drawbar n oseweight ,i f
applicable). The gross vehicle weight ratin gi s
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: R
the curb weight of the vehicle R
the weight of the accessories R
the load limit R
the weight of the factory installed optional
equipment
Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1p si. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index In addition to the load-bearin gi ndex ,t he load
index may also be imprinted on the sidewall of
the tire. This specifies the load-bearin gc apacity
more precisely.
Curb weight The weight of av ehicle with standard equipment
includin gt he maximum capacit yoff uel, oil and
coolant .Ita lso includes the air-conditionin gs ys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage.
Maximum load rating
The maximum tire load is the maximum permis-
sible weight in kilogram sorl bs for which at ire is
approved.
Maximum permissible tir ep re ssure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated by
dividing the maximum axle load of one axle by
two.306
All about wheels and tires
Wheels and tires

Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at aq ualified spe-
cialist workshop.
Observe the instructions and safety notes in the
"Changing aw heel" section ( Y
page 307).
The wear pattern sont he front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before ac lear wear pattern
has formed on the tires. Fron tt ires typically
wear more on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotat et he wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,00 0k m) .D ependin gont ire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time aw heel is rota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system
(Canada only) or the tire pressure monitor (USA
only).
Direction of rotation Tires with as pecified direction of rotation have
additional benefits ,e .g. if there is ar isk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
An arrow on the sidewall of the tire indicates its
correc td irection of rotation.
Storing wheels Stor ew heels that are not being used in ac ool,
dry and preferably dark place. Protec tt he tires
from oil, grease, gasoline and diesel. Mounting aw heel
