Minor Repairs

Tire replacements
f
Use only tire makes and types tested by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same manufacturer and
with the same specification code (e.g. “N0”,
“N1”…) should be mounted on the vehicle.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Use tires with “ZR” quality standards.
There
are currently no standards concerning tire
strength at speeds above 150 mph (240 km/h).
Tires should be replaced no less than on one axle
at the time. Only tires of the same make and type
must be used. Mixed tires are not permissible and
will affect vehicle performance, safety, and can
affect vehicle warranty.
Porsche dealers can recommend the most current
replacement tire options for your vehicle.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km).
Tires must always remain on the same side
of the vehicle.
When wheels are removed, the direction of
rotation and position of each wheel should be
marked.
If new tires are installed only on
one
axle, a
noticeable change in handling occurs due to the
different tread depth of the other tires. This
happens especially if only rear tires are replaced.
However, this condition disappears as the new
tires are broken in.
f
Please adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
f
Use only plastic valve caps.
f
Please read the fitting and replacement
instructions regarding metal valves.
f
Use original Porsche metal valves only.
f
Valve inserts with valve caps protect against
soiling.
Soiled valve inserts can cause a gradual loss
of air
.
Parking at the curb
Hard impacts against curbs (or traffic islands) are
dangerous and may cause hidden tire damage
which is not noticeable until later. Such damage
can result in accidents at high speeds. Depending
on the force of impact, the edge of the rim can
also be damaged.
f
After such an impact, have the wheel checked
by an expert.
f
If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
Exercise care when parking along curbs.
Information
Tire repairs are not permissible under any
circumstances.
