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 authorized Porsche dealer.
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.fStop the vehicle and check the tires.fIf no cause for the fault can be found, drive carefully to the nearest authorized Porsche dealer.
The summer tires of your Sports Car have been specially developed and adapted for high performance. At low outside temperatures (<15°C (60°F)), the tire characteristics change. This can result in noises occurring when parking or maneuvering at low outside temperatures.
Wheels with Tire Pressure Monitoring System (TPMS) sensors
Before changing wheels, make sure that the wheels are compatible with your vehicle’s TPMS.fCheck this with your authorized Porsche dealer.
Removing and storing tires
fAfter changing, adjust tire pressure and torque wheel bolts diagonally. Please see the chapter “CHANGING WHEELS” on page 254.fStore tires in a cool and dry place. Rotate periodically to avoid flat spots.fDo not store summer tires or park vehicles fitted with summer tires at ambient temperatures below 5 °F (-15 °C).fAvoid 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.
Information
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 numbers read 1213, then the tire was produced in the 12th week of 2013.
Snow tires
The installation of Porsche approved snow tires is recommended.
Use Porsche approved snow tires for grip on snow and ice. Summer performance tires are not suitable for usage in cold, snowy, or icy conditions.Check with your local Motor Vehicle Bureau for possible restrictions.

15. 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 (160 Nm/118 ftlb.).
Note on operation for vehicles with Tire Pressure Monitoring
fOn vehicles with Tire Pressure Monitoring, the settings on the multi-function display must be updated after the wheel change.fPlease see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.
Checking tire pressure with a pressure gauge
1. Remove the valve stem cap from the tire. 2. Press the pressure gauge onto the valve stem.
Information
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 permissible tire pressure.This information can be found on the tire pressure plate or in the chapter Technical Data.4. Remove the pressure gauge. 5. Please see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.

Wheels with Central Lock
Racing technology for the road. Wheels with a central lock are perfectly normal in motor sport, but are not common on normal roads.Instead of the central lock nuts conventionally used in motor sport, the wheel has an encapsulated central bolt, which is used to fasten it to the wheel hub.
Driving on a race circuit (e.g. sports driving school, club sport events)
Wheels are subjected to significantly higher stresses during extremely sporty driving – particularly when driving on race circuits – compared to driving on public roads. For this reason, all the instructions specified below must always be noted and followed for driving on race circuits.fAlways make enquiries with your authorized Porsche dealer about any other driving and maintenance instructions before driving on race circuits.
The central lock, like all chassis components, requires greater attention while driving on race circuits.fCheck the tightening torque of the central bolts before, if necessary during and after driving on a race circuit.fWhenever wheels are changed, apply some aluminum paste to the trapezoidal thread on the wheel hub or have a second set of greased screws on hand.fNever drive the vehicle without a central lock bolt in the hub.fAll central wheel lock components, such as the central bolt, wheel, wheel hub, wheel hex and brake disk must always be checked for wear and replaced if necessary after driving on a race circuit.
fAxis components subject to high loads must be replaced at intervals specified by Porsche . Always make enquiries with your authorized Porsche dealer about the current stipulations before driving on race circuits.fOther parts such as ball joints, rubber mounts, etc., where wear may result in modified vehicle handling, must be checked and if applicable replaced without delay.
Deferring inspection, maintenance and replacement measures can result in accidents.
This is particularly true if you are clocking up high mileage on race circuits . We recommend that you get an authorized Porsche dealer to carry out these measures.
Components can break or become damaged. Unsuitable wheel sizes or incorrectly dimensioned components in the hub area of accessory wheels , the use of spacers, etc. can impair the overall function of the wheel mounting.fOnly use wheel/tire combinations approved by Porsche.fUnder no circumstances should spacers be used.
Central Bolts
The central bolt and central bolt lock are safety-related components. Always check them for signs of wear and damage.fThe conical surface, trapezoidal thread and inner toothing of the central bolt must not be scratched or cracked.fReplace damaged central bolts.Only use the genuine Porsche central bolts allocated specifically to this vehicle model.fThe conical surface and trapezoidal thread on the central bolt must be perfectly clean.
Tightening torque for central bolts: 443 ftlb. (600 Nm).
Changing a Wheel
fGet an authorized Porsche dealer to change the wheel.
Information
The tools required for changing a wheel (e.g. jack, torque wrench) are not supplied as standard with the car. Your authorized Porsche dealer will be pleased to advise you.
Deferred inspection, maintenance and replacement measures
Inadequate screw connections when using unapproved components and wheels

Minor Repairs 259
If a wheel needs to be changed, the procedure described below must be adhered to exactly, as otherwise the wheel may loosen, resulting in damage. Porsche cannot be held liable if this happens.To achieve the high tightening torque required for the central bolt, a suitable, commercially available 443 ftlb. (600 Nm) torque wrench must be used. Alternatively, a corresponding tool with torque multiplier (part no. 997.450.323.90) is available from Porsche Motorsport. When a torque multiplier is used, the torque must be reduced in accordance with the tool’s operating instructions.
When loosening and fastening the wheel, a second person is needed to prevent the wheel from turning by firmly braking it.
The high mounting forces involved can cause the vehicle to roll away and slip off the jack.fAlways use a lifting platform if there is one available.
Risk of damage due to vehicle tipping over or falling off lifting equipment or using the wrong tool.
The high mounting forces involved can cause the vehicle to roll away and slip off the jack. An impact wrench can damage the central lock.fAlways use a lifting platform if there is one available.fDo not use an impact wrench .
1. Apply the electric parking brake, move the PDK selector lever to position P and remove the key from the ignition.2. Secure the vehicle carefully in both directions to prevent it from rolling away, e.g. using wedges at the wheels on the opposite side.This is particularly important on slopes.3. Raise the vehicle until the wheel lifts off the ground. Lift the vehicle only at the specified jacking points.fPlease see the chapter “RAISING THE VEHICLE WITH A LIFTING PLATFORM, TROLLEY JACK OR STANDARD JACK” on page 254.
Information
The vehicle must not be standing on the wheel to be secured during fitting.
4. Open the luggage compartment and lift the plastic cover A. Please see the chapter “TIRE FILLING COMPRESSOR” on page 198.Open the receptacle B and remove the polygon tool.The central bolt must only be opened using this original polygon tool. Always leave the polygon tool in the luggage compartment to ensure that it is always available in the event of a breakdown.
Risk of damage from scratching.fProceed with care when removing the wheel-hub cap.

5.The polygon tool contains an auxiliary tool. Remove this from the square and replace it afterwards.Use the auxiliary tool to carefully lever the wheel-hub cap out of its seating. For this purpose, insert the metal tongue of the auxiliary tool deep into the opening groove A on the central bolt and then swivel the handle back.
6. Position the polygon tool and insert it until it engages . This opens the safety lock on the central bolt.
Information
A very high torque is required to loosen the central bolt, especially if it has not been opened in a long time.
fTurn in the correct direction.fMake sure there is sufficient clearance so that neither people nor vehicle parts will be harmed if the lever breaks away.fThe wheel should be prevented from turning by getting a second person to brake firmly using the brake pedal.fHold the steering wheel securely when loosening the front wheels.
Risk of damage to the central bolt lock.fWhen loosening the central bolt, make sure that the tool remains pushed on fully and does not slide out of position.
7. Unscrew the central bolt and set it down in such a way that no dirt can enter the cone area or the thread.

Information
The vehicle must not be standing on the wheel to be secured during fitting.
12. Insert the central bolt into the polygon tool (until it engages), fit the central bolt at right angles to the wheel hub and screw it on without tilting.13.Tighten the central bolt to 443 ftlb. (600 Nm) using a suitable torque wrench. Prevent the resultant turning of the wheel by getting a second person to firmly press the brake pedal. Hold the steering wheel securely when tightening the front wheels.
14. Loosen the central bolt again by 1/4 turn. 15. Tighten the central bolt again to 443 ftlb. (600 Nm) .
Information
If you do not have a suitable torque wrench in a breakdown situation, the emergency procedure for fastening the central bolt must be performed.fPlease see the chapter “CENTRAL BOLT EMERGENCY FASTENING” on page 263.
16. Remove the polygon tool and check whether the locking pin C has already automatically engaged in the central bolt. The locking pin then completely covers the inner teeth of the central bolt. The locking pin is usually still in the rear position and must be turned to the left and right slightly using the auxiliary tool until it engages with spring force in the central bolt.
