Practical Tips, Emergency Service

Wheel alignment, wheel balancing

Unbalanced wheels may affect car handling and

tire life.

Only the specified weights may be used for wheel

balancing.

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 au-

thorized Porsche dealer.

Danger!

If, during a journey, uneven running or vibra-

tions occur that could be caused by damage

to tires or the car, the speed must be re-

duced 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 se-

vere personal injury.
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.

Removing and storing tires

Tires must always remain on the same side of

the vehicle.

When wheels are removed, the direction of rota-

tion 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 and direction of rotation arrow.
The preception that tire durability and perfor-

mance are immune to the effects of storage and

age is unfounded.

Chemical additives, which make the rubber elas-

tic, lose their effectiveness in 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

4 years be used on your Porsche.
The age of the tire can be obtained from the “DOT”

code number. If, for example, the last four num-

bers read 3203, then the tire was produced in the

32th week of 2003.
f Store tires in a cool and dry place.
