162 Wheels and Tyres
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend changing the
front wheels around with the rear wheels as shown in the diagram
then obtain approximately the same life for all the tyres.
It may be advantageous to swap the tyres over "crosswise" when certain types of wear
characteristic arise on the running surface of the tyres (but not in the case of unidirec-
tional tyres). Specialist garages are familiar with details.
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.
New tyres and wheels
Tyres and wheel rims are important design elements. One should therefore use the
tyres and wheel rims which have been released for use by Škoda Auto. They are exactly
matched to the vehicle type and therefore contribute significantly to good road
holding and safe driving characteristics 
Only fit radial tyres of the same type on all 4 wheels, size (rolling circumference) and,
if possible, the same tread pattern on one axle.
The specialist garages have access to the most current information about which tyres
we have released for use on your vehicle.
We recommend that you have any work relating to tyres or wheels carried out by a
specialist garage. Specialist garages have all of the necessary special tools and

replacement parts available plus the required specialist knowledge and are also in a
position to properly dispose of the old tyres. A large number of specialist garages also
have an attractive range of tyres and wheels available.
The tyre/wheel combinations which are approved for your vehicle are indicated in
your vehicle documents. Approval and licensing may differ according to the legislation
prevailing in individual countries.
Proper knowledge of the tyre data makes it easier for you to select the correct type of
tyre. Tyres do, 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 - R adial
15 Diameter of wheel in inches
91 Load index
T Speed symbol
The following speed restrictions apply to tyres.
