Practical Tips, Emergency Service

Wheel alignment, wheel balancing As a precaution, have wheels with summer tires
balanced in the spring, and those with mud and
snow tires before winter.
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.
Warning!
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.
fStop the vehicle and check the tires.
fIf no cause for the fault can be found, drive
carefully to the nearest authorized Porsche dealer.
Removing and storing tires fAfter changing, adjust tire pressure and torque
wheel bolts diagonally to 94 ftlb (130 Nm).
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 preception that tire durability and perform-
ance 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 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 four num-
bers read 1204, then the tire was produced in the
12th week of 2004.
fStore tires in a cool and dry place.

Practical Tips, Emergency Service
Wheel Bolts
Warning!
Risk of wheel bolt breakage and wheel sepa-
ration, resulting in severe personal injury or
death.
fFollow all instructions concerning wheel bolts. fAlways clean the wheel bolts before fitting.
fApply a thin coat of Optimoly TA (aluminium
paste) on the thread and between the bolt head
and movable spherical cap ring (arrows).
The bearing surface of the spherical cap
facing the wheel must not be greased.
fReplace damaged wheel bolts.
Only use the Original Porsche wheel bolts spe-
cially designed for this vehicle type.
Tightening torque Tightening torque of wheel bolts:
130 Nm/96 ftlb.
Wheel Securing Bolts The wrench socket for the wheel securing bolts is
in the tool pocket.
To loosen or tighten the wheel bolt with anti-theft
protection, a wrench socket with the appropriate
coding must be used between the wheel bolt and
the wheel-bolt spanner.
fWhen positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
If the wheels have to be removed at the workshop,
please do not forget to hand over the wrench
socket for the wheel securing bolts along with the
car key.
Note on operation
On vehicles with 17 mm spacers on the rear axle,
the wheels are secured with wheel nuts.
On request, separate anti-theft protection for the
wheel nuts can be mounted.
Please consult an authorized Porsche dealer.

Screw in two assembly aids for vehicles with Porsche
Ceramic Composite Brake6. Take the wheel off and put a new wheel on.
7. Please observe the chapter “WHEEL BOLTS”
on Page 248.
Screw in wheel bolts; remove assembly aids
and screw in the remaining wheel bolts. Initially
tighten bolts in diagonally opposite sequence
so that the wheel is centered.8. Lower the car completely.
9. Tighten wheel bolts in diagonally opposite
sequence.
Immediately after changing a wheel, use a
torque wrench to check the prescribed
tightening torque (130 Nm/96 ftlb.).
Checking tire pressure with a
pressure gauge1. Remove the valve stem cap from the tire.
2. Press the pressure gauge onto the valve stem.
Note on operation
fDo not press too hard or force the valve stem
sideways, or air will escape.
If the sound of air escaping from the tire is
heard, reposition the pressure gauge.
3. Read the tire pressure on the gauge stem and
compare it to the permissble tire pressure.
This information can be found on the tire pres-
sure plate or in the chapter Technical Data.
Please observe the chapter “TIRE PRESSURES
FOR COLD TIRES” on Page 290.
4. Remove the pressure gauge.
fPlease observe the chapter “TPC TIRE PRES-
SURE MONITORING” on Page 109.

Practical Tips, Emergency Service
17 mm spacers
911 Carrera 4, 911 Carrera 4S
Danger!
Risk of accident.
17 mm spacers must only be mounted on the
rear axle together with 11.5 J x 19 (67 mm
rim offset) wheels.
fAlways remove 17 mm spacers before
mounting other wheel sizes or an emergency
spare wheel because the wheel cannot be mounted correctly.
fFor information on the spacers: Please
observe the chapter “SPACERS” on Page 249.
Removing the spacers
1. Unscrew the wheel bolts A with which the
spacer is fastened.
2. Remove the spacer.
3. Screw in 1 or 2 assembly aids instead of the
wheel bolts.
4. Fit wheel. 5. Please observe the chapter “WHEEL BOLTS”
on Page 248.
Insert wheel bolts A and tighten by hand.
Remove assembly aids, screw in remaining
wheel bolts.
Initially tighten bolts slightly in diagonally
opposite sequence so that the wheel is
centred.
6. Lower the car completely.
7. Tighten wheel bolts in diagonally opposite
sequence.
Immediately after changing a wheel, use
a torque wrench to check the prescribed
tightening torque of the wheel bolts
(130 Nm/96 ftlb.).fStore spacer and wheel nuts together.
Mounting the spacers
1. Remove wheel.
2. Fit the spacer with the wheel bolts A used to
fasten the wheel.
Initially tighten the wheel bolts slightly in
diagonally opposite sequence.
3. Tighten wheel bolts in diagonally opposite
sequence.
Tightening torque: 130 Nm (96 ftlb.).
4. Fit wheel.
To d o t h i s use the original wheel nuts for
fastening the wheels.
Tightening torque: 130 Nm (96 ftlb.).
fPlease observe the chapter “CHANGING A
WHEEL” on Page 250.
