Minor Repairs
Self-adhesive weights must not come into contact
with cleaning agents, since they could drop off.
Uneven tread wear indicates wheel imbalance. In
this event, the vehicle should be checked at an
authorized Porsche dealer.
Danger!
If, during a trip, uneven running or vibrations
occur that could be caused by damage to
tires or the car, the speed must be reduced
immediately, but without braking sharply. If
you continue your trip without having the
cause of the fault remedied, you might lose
control of your vehicle which could cause
serious personal injury or death.
f
Stop the vehicle and check the tires.
f
If no cause for the fault can be found, drive
carefully to the nearest authorized Porsche
dealer.
Wheels with Tire Pressure Monitoring
(TPM) sensors
Before changing wheels, make sure that the
wheels are compatible with your vehicle’s TPM.
f
Check this with your authorized Porsche
dealer.
Removing and storing tires
f
After changing, adjust tire pressure and torque
wheel bolts diagonally.
Please see the chapter “CHANGING A WHEEL”
on page 291.
f
Store tires in a cool and dry place.
Rotate
periodically to avoid flat spots.
f
Avoid contact with fuel, oil and grease.
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.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with
their marking.
The perception that tire durability and
performance are not affected by storage and age
is unfounded.
Chemical additives, which make the rubber
elastic, lose their effectiveness over the course of
time and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from
time to time.
Note
Under no circumstances should tires older than
6 years be used on your Porsche.
The age of the tire can be obtained from the ”DOT“
code number. If, for example, the last three
numbers read 1208, then the tire was produced in
the 12th week of 2008.
