Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres.
With greater additional load, adjust the tyre inflation pressure accordingly.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. When driving, however, there are a
range of factors that may result in an imbalance. This may become apparent by a
“vibration” in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
Incorrect wheel alignment at the front or rear leads to excess wear of the tyres.
Tyre damage
Drive over kerbs and other such obstacles slowly and at right angles wherever
possible in order to avoid damage to tyres and wheel trims.
We recommend checking your tyres and wheel rims for damage (punctures, cuts,
splits and bulges, etc.) on a regular basis. Remove foreign bodies (e.g. small
stones) from the tyre tread immediately.
Replacing wheels
If significantly greater wear is present on the front tyres, we recommend replac-
ing the front wheels with the rear wheels as shown in the diagram » Fig. 142 . You
will then obtain approximately the same life for all the tyres.
We recommend that you swap the tyres every 10,000 km in order to achieve even wear on all tyres and to ensure optimal service life for the tyres.
Storing tyres
Identify disassembled tyres so that the previous direction of rotation can be maintained if the tyres are reassembled.
Always store wheels or tyres in a cool, dry place that is as dark as possible. Tyres
which are not fixed to a wheel trim should be stored upright.
Wear indicators
The base of the tread of the tyres has 1.6 mm high wear indicators installed.
These wear indicators are evenly spaced around the circumference of the tyre, depending on the make » Fig. 141 -
. Markings on the walls of the tyres through
the letters “TWI”, triangular symbols or other symbols identify the position of the
wear indicators.Tyre age
Tyres age and lose their original characteristics, even if they are not being used.
Therefore, we recommend not using summer or winter tyres older than 6 or 4
years old respectively.
New tyres
First read and observe the introductory information and safety warn-
ings
on page 175.
Only use radial tyres of the same type, size (rolling circumference) and tread pat-
tern on one axle on all four wheels.
The tyre/wheel combinations which are approved for your vehicle are indicated in
your vehicle documents.
Where possible, replace tyres by axle. Always fit the tyres with the deeper tread
depth to the front wheels.

What this means is:
195Tyre width in mm » Fig. 141 on page 176 - 65Height/width ratio in % » Fig. 141 on page 176 - RCode letter for the type of tyre – Radial » Fig. 141 on page 176 - 15Rim diameter in inches » Fig. 141 on page 176 - 85Load index » HSpeed symbol »
The date of manufacture is stated on the tyre wall (possibly on the inside). e.g.
DOT ... 10 13 ..
means, for example, that the tyre was manufactured in the 10th week of 2013.
