WARNING (Continued)■Never use the emergency spare wheel if it is damaged.■Observe the instructions on the warning sign of the temporary spare
wheel.
Tyre label
Read and observe
on page 116 first.
Only use radial tyres of the same type, size (rolling circumference) and treadpattern on one axle on all four wheels.
When mounting new tires the tires have to be replaced axle by axle.
Explanation of tyre markings
For example, 175/65 R 14 82 T means:

The date of manufacture is stated on the tyre wall (possibly on the inside).
For example DOT ... 10 15... means, for example, that the tyre was manufac-
tured in the 10th week of 2015.

Do not use alloy rims with bevelled or polished surfaces during the winter. The
rim surface does not have sufficient corrosion protection and could be perma-
nently damaged (e.g. through grit).
Winter tyres
The handling of your vehicle will be significantly improved when driving on
wintry roads if you fit winter tyres (labelled M+S).
To obtain the best possible handling, winter tyres must be fitted to all four
wheels. The minimum tread depth must be 4 mm.
Fit the summer tyres on again in good time as they provide better handling
properties, 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.
Speed symbol
Winter tyres (marked with M+S and a peak/snowflake symbol
) 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.
