Changing a wheel
Warning!
Risk of serious personal injury or death. The
car may slip off the jack.
f Make sure that no one is in the vehicle when
jacking up and changing a wheel.
f Always place the car on stable supports if work
has to be carried out under the car.
Risk of damage to the brake discs of the
Porsche Ceramic Composite Brake (PCCB).
f Always screw in both assembly aids when changing a wheel.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids) are not sup-
plied with the car.
Your authorized Porsche dealer will be pleased to
advise you.
1. Apply the handbrake fully and engage 1st gear or PDK selector-lever position P and remove
the ignition key.
2. Switch on the hazard warning lights if neces- sary.
3. Secure the car against rolling away, e.g. by
means of wedges under the wheels on the op-
posite side.
This is particularly important on slopes. 4. Slightly slacken the whee
l bolts of the wheel to
be changed.
5. Lift the car only at the specified jacking points.
6. Raise the car until the wheel lifts off the ground.
Please see the chapter “LIFTING THE VEHICLE
WITH A LIFTING PLATFORM OR GARAGE LIFT”
on Page 232.
7. Remove 1 or 2 wheel bolts (see respective illustration).
8. Screw in assembly aids instead of the wheel bolts.
Screw in assembly aid for cars without Porsche Ceramic
Composite Brake9. Remove the remaining wheel bolts.

Screw in two assembly aids for cars with Porsche
Ceramic Composite Brake10.Take the wheel off and put a new wheel on.
Please see the chapter “WHEEL BOLTS” on
Page 226.
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 PRESSURE FOR
COLD TIRES (68 °F/ 20 °C)” on Page 267.
14.Lower the car fully and remove the jack.
15.Tighten wheel bolts in diagonally opposite sequence.
f Immediately 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
f On vehicles with Tire Pressure Monitoring, the
settings on the on-board computer must be
updated after the wheel change.
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/ 20 °C)” on Page 267.
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 PRESSURE FOR
COLD TIRES (68 °F/ 20 °C)” on Page 267.
4. Remove the pressure gage.
f Please see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 151.

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.

2. Remove the spacer.
3. Fasten the brake disc with the short M6x12
countersunk screws, part No.:
900.269.047.09.
Tightening torque 7.5 ftlb. (10 Nm) .
4. For wheel mounting without a spacer, 5 mm
shorter wheel bolts (part No.:
997.361.203.01 ) must be used.
Tightening torque: 96 ftlb. (130 Nm) .

Tire and rim sizes Extensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer has information
about approved tires and wheels and is happy to assist you. If aftermarket tires and/or wheels are installed which are not
approved by Porsche, the vehicle’s roadability and handling characteristics might be impaired. Since Porsche has no data on
such combinations, Porsche cannot st and behind the safety or durability of these aftermarket combinations.
Snow chains Can be mounted only on the rear wheels; maximum speed 30 mph/50 km/h. Use only Porsche authorized fine-link
cross-type or edge chains. Snow chain clearance can be guaranteed only with the tire + rim combination marked*
without spacers. Please see the chapter “SPACERS” on Page 233.
