ton must become visible when the hardtop is
locked properly.

Parking at the curb
Warning!
Hard impacts against curbs (or traffic
islands) are dangerous and may cause hid-
den tire damage which is not noticeable until
later. Such damage can result in accidents at
high speeds causing serious personal injury
or death.
Depending on the force of impact, the edge
of the rim can also be damaged.
fIf you are in doubt, have the wheel checked by
an expert, particularly if you suspect damage
on the inside.
fIf you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle. Exercise care when parking along curbs.
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 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 se-
rious personal injury or death.
fStop the vehicle and check the tires.
fIf no cause for the fault can be found, drive
carefully to the nearest authorized Porsche dealer.
Wheels with Tire Pressure Monitoring
(TPM) sensorsBefore changing wheels, make sure that the
wheels are compatible with your vehicle's TPM.
fCheck this with your 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 perception 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.

Practical Tips, Emergency Service
Wheel Bolts
Danger!
Risk of wheel bolt breakage and wheel sepa-
ration, resulting in serious personal injury or
death.
fFollow all instructions concerning wheel bolts. fAlways clean the wheel bolts before fitting.
fApply a thin coat of Optimoly TA (aluminum
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:
96 ftlb./130 Nm
Wheel Securing Bolts 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.
The wrench socket for the wheel securing bolts is
in the tool box.
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.

Screw in two assembly aids for vehicles with Porsche
Ceramic Composite Brake10.Take the wheel off and put a new wheel on.
Please see the chapter “WHEEL BOLTS” on
Page 248.
11.Insert wheel bolts and tighten by hand.
12.Remove assembly aids, screw in remaining
wheel bolts.
Initially tighten bolts only slightly in diagonally
opposite sequence so that the wheel
is centred.13.Inflate the tire if necessary.
Please see the chapter “TIRE PRESSURES FOR
COLD TIRES (68 °F / 20 °C)” on Page 289.
14.Lower the car fully and remove the jack.
15.Tighten wheel bolts in diagonally opposite
sequence.
fImmediately after changing a wheel, use
a torque wrench to check the prescribed
tightening torque (96 ftlb./130 Nm).
Note on operation for vehicles with
Tire Pressure Monitoring
fOn vehicles with Tire Pressure Monitoring, the
settings on the on-board computer must be
updated after the wheel change.
fPlease see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 143.
Checking tire pressure with a
pressure gage1. Remove the valve stem cap from the tire.
2. Press the pressure gage 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 gage.
3. Read the tire pressure on the gage 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 see the chapter “TIRE PRESSURES FOR
COLD TIRES (68 °F / 20 °C)” on Page 289.
4. Remove the pressure gage.
fPlease see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 143.

Spacers911 Carrera, 911 Carrera SfUse the spacers only together with wheels and
fastening parts approved by Porsche.
Before having spacers fitted, find out about the
current approval status.
Mounting an emergency spare wheel
If 5 mm spacers are mounted, these must not be
removed to mount an emergency spare wheel.
Fitting snow chains
The use of snow chains is not permitted when
5 mm spacers are mounted.
Caution!
Risk of damage to the wheel housings if the
5 mm spacers are not removed before fitting
snow chains.
fTo permit the fitting of snow chains, have the 5 mm spacers removed on all 4 wheels.Note on operation
fTo fit/remove the spacers:
Please consult an authorized Porsche dealer.
fPlease see the chapter “CHANGING A WHEEL”
on Page 249.
Removing the spacers
