Changing wheels around
First read and observe the introductory information and safety warn-
ings on page 170.
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend chang-
ing the front wheels around with the rear wheels as shown in the dia-
gram » Fig. 141. You will then obtain approximately the same life for all the tyres.
We recommend that you change the wheels around every 10
000 km in order to
achieve even wear on all wheels and to obtain optimal tyre life.
Storing tyres
Mark wheels before removing them so that their previous direction of running can
be maintained when mounted them again.
Always store wheels or tyres which been removed in a cool, dry and, where possi-
ble, dark place. Tyres which are not fixed to a wheel trim should be stored up-
right. ÐNew wheels and tyres
First read and observe the introductory information and safety warn-
ings on page 170.
Only fit tyres of the same type, size (rolling circumference) and the same tread
pattern on one axle on all 4

wheels.
The tyre/wheel combinations which are approved for your vehicle are indicated in
your vehicle documents.
ä
ä Proper knowledge of the tyre data makes it easier for you to select the correct
type of tyre. Tyres, for example, have the following inscription on their walls.
195/65 R

15 91 T
What this means is:
195 Tyre width in mm
65 Height/width ratio in %
R Code letter for the type of tyre - Radial
15 Diameter of wheel in inches
91 Load index
T Speed symbol The following speed restrictions apply to tyres.
Speed symbol Permissible maximum speed
S 180 km/h
T 190 km/h
U 200 km/h
H 210 km/h
V 240 km/h
W 270 km/h
Y 300 km/h The date of manufacture
is also stated on the tyre wall (possibly only on the in-
side of wheel ): e.g.
DOT ... 20 12...
means, for example, that the tyre was manufactured in the 20th week of 2012.
The following must be observed if only one temporary spare wheel is availa-
ble » page 173 . Ð
172 General Maintenance

Full wheel trim
First read and observe the introductory information and safety warn-
ings on page 170.
Pulling off
›
Hook the clamp found in the vehicle tool kit into the reinforced edge of the
wheel trim.
› Push the wheel wrench through the clamp, support on the tyre and pull off the
wheel trim.
Install
› First press the full wheel trim onto the wheel rim at the valve opening provided.
Then press the full wheel trim into the wheel rim until its entire circumference
locks correctly in place. CAUTION
■ Use the pressure of your hand, do not knock the full wheel trim! Heavy knocks
mainly on the points where the full wheel trim has not been inserted into the
wheel, can result in damage to the guide and centring elements of the full wheel
trim.
■ First of all check that the theft-deterrent wheel bolt is located in the hole near
the valve before fitting the full wheel trim onto a steel wheel which is attached
with a theft-deterrent wheel bolt » page 182, Securing wheels against theft .
■ If wheel trims are retrofitted it must be ensured that an adequate flow of air is
assured to cool the brake system. ÐWheel bolts

First read and observe the introductory information and safety warn-
ings on page 170.
Pulling off
›
Push the plastic clip sufficiently far onto the cap until the inner catches of the
clip are positioned at the collar of the cap and detach the cap » Fig. 143.
Install
› Push the caps onto the wheel bolts up to the stop.
The wheel bolt caps are housed in a plastic box in the spare wheel or in the stor-
age space for the spare wheel. Ð Wheel trim caps

174 General Maintenance

Wheel bolts
First read and observe the introductory information and safety warn-
ings on page 170.
Wheels and
wheel bolts are matched to each other in terms of design. Each time
you fit other wheels, e.g. light alloy wheels or wheels with winter tyres, you must
therefore also use the matching wheel bolts of the correct length and shape of
spherical cap. This is essential to ensure that the wheels are tightly fitted and
that the brake system operates properly. ÐWinter tyres
First read and observe the introductory information and safety warn-
ings on page 170.
The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber
blend, tread pattern). This particularly applies to vehicles which are equipped with
low-profile tyres
or high-speed tyres (code index H or V on wall of tyre).
To achieve the best possible handling properties, winter tyres must be fitted on
all 4 wheels, the minimum tread depth must be 4
mm and tyres must be no older
than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum
speed of the vehicle is higher. For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, and reduced tyre wear on roads
which are free of snow and ice as well as at temperatures above 7

°C. The fuel
consumption is also lower. ÐSnow chains
First read and observe the introductory information and safety warn-
ings on page 170.ä
ä
ä Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
For technical reasons, it is only permissible to fit snow chains with the following
wheel/tyre combinations.
Wheel size Depth (D)Tyre size
6J x 15 a)
47 mm 195/65
6.5J x 15 a)
50 mm 195/65
6J x 16 a)
50 mm 205/55
6J x 17 b)
45 mm 205/50 a)
Only fit snow chains with links and locks not larger than 15 mm.
b) Only fit snow chains with links and locks not larger than 9 mm.
Remove the full wheel trims before installing the snow chains.
Observe the national legal regulations relating to the use of snow chains and the
maximum vehicle speed with snow chains. CAUTION
The chains must be removed when driving on roads which are free of snow. They
adversely affect the handling of your vehicle, damage the tyres and are rapidly
destroyed. Ð176
