Improper handling can damage the wheel surface.
Carry out tire removal and mounting using a bead holding-down device only.
Use a leather pad on the rim flange to support the valve insertion tool.
Only use the Porsche centring clamping set for balancing.
Do not use hard brushes to clean the wheels as these can cause deep scratches that cannot be removed by
polishing.
Never use solvents or other chemical substances not approved by Porsche on tires.

Arrow with inscriptions “Rotation” and

= Directional mounting on specified side only.
Information
In principle, only tires that at least correspond to the maximum vehicle speed may be installed on the vehicle.
There may be national exemptions for winter tires marked for M+S and 3PMSF (3 peak mountain snow flake),
which also permit tires that do not correspond to the maximum vehicle speed.
Information
"N..." = Specification code of the tire, e.g. "NA0", "NA1", "NA2" ... The complete “N ...” code of the relevant tire
makes must be shown on the tire sidewall near the type designation.
Instructions for correct mounting of the tires are also given on the tire sidewall. If there are no mounting
instructions on the tire sidewall, the tire must be mounted so that the DOT marking is visible from the
outside.
Information
As a general rule, Porsche does not recommend having tires repaired. Local legislation must always be
observed.
It is advisable to install winter tires for temperatures below 7 °C (44 °F), because the driving characteristics
of summer tires and UHP tires are reduced at low temperatures. Subfreezing temperatures can cause
permanent damage to summer tires and UHP tires.
When replacing a tire on an axle, make sure that the tread depth of the new tire does not differ from that of
the other tire by more than 30%. If this value is exceeded, we recommend that you replace both tires.
WARNING
Driving with different tires (mixed tires)
•
Uncontrollable vehicle handling
Þ
⇒
Only use tires of the same make and type, with the same speed index and the same specification code (NA0, NA1, NA2,
etc.) on a vehicle.

WARNING
Incorrect tire pressure
