Tire replacements
fUse only tire makes and types tested by Porsche.
If you do not use a Porsche recommended replacement tire, make sure that you purchase your new tires from a reputable tire dealer and that the dealer complies with all manufacturers warnings for those tires.
Only tires with the same manufacturer and with the same specification code (e.g. “N0”, “N1”…) should be mounted on the vehicle.
Before mounting new tires, check with your Porsche dealer about the current release status.
Use tires with “ZR” quality standards. There are currently no standards concerning tire strength at speeds above 150 mph (240 km/h).
Tires should be replaced no less than on one axle at the time. Only tires of the same make and type must be used. Mixed tires are not permissible and will affect vehicle performance, safety, and can affect vehicle warranty.
Porsche dealers can recommend the most current replacement tire options for your vehicle.
Initially, new tires do not have their full traction. You should therefore drive at moderate speeds during the first 60 - 120 miles (100 - 200 km).
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.
If new tires are installed only on one axle, a noticeable change in handling occurs due to the different tread depth of the other tires. This happens especially if only rear tires are replaced. However, this condition disappears as the new tires are broken in.fPlease adjust your driving style accordingly.
Installation of new tires should only be done by a qualified tire technician.
Valves
fUse only plastic valve caps.fPlease read the fitting and replacement instructions regarding metal valves.fUse original Porsche metal valves only.fValve inserts with valve caps protect against soiling.Soiled valve inserts can cause a gradual loss of air.
Parking at the curb
Hard impacts against curbs (or traffic islands) are dangerous and may cause hidden tire damage which is not noticeable until later. Such damage can result in accidents at high speeds. Depending on the force of impact, the edge of the rim can also be damaged.fAfter such an impact, have the wheel checked by an expert.fIf you must drive over a curb or other obstacle, drive slowly and at an obtuse angle. Exercise care when parking along curbs.
Information
Tire repairs are not permissible under any circumstances.

The standard tires profile and rubber mixture are optimized for wet and dry driving conditions, and may not prove favorable for snow conditions.fInstall snow tires before driving in such conditions.
Risk of insufficient road grip leading to loss of control and damage to the vehicle.
The standard tires profile and rubber mixture are optimized for wet and dry driving conditions, and may not prove favorable for snow conditions.fInstall snow tires before driving in such conditions.
Before mounting snow tires, consult with your Porsche dealer. They have the technical information necessary to advise you on wheel and tire compatibility.fSnow tires should have the same load capacity as original equipment tires and should be mounted on all four wheels.
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases the rate of wear of the affected tires and causes damage.
Tires with badly worn treads are very dangerous and could cause accidents.fMake sure they are replaced immediately.fDo not exceed the snow tire speed rating.
Snow tires do not have the same degree of traction on dry, wet or snowfree roads as normal tires. Furthermore, snow tires wear rapidly under these conditions.
Information
We recommend that you fit snow tires on the vehicle at temperatures below 45 °F (7 °C) since the driving performance of summer tires is reduced at low temperatures and a lower level of comfort can also be expected. For example, juddering noises caused by the tires can occur while maneuvering the vehicle or accelerating out of bends on both dry and wet road surfaces.Extremely low temperatures of below 5 °F (-15 °C) can cause permanent damage to summer tires.
Snow tires lose their suitability when their tread depth falls below 5/32 in. (4 mm).
Comply with all state and local laws governing snow tire and tread depth requirements.
Exceeding the maximum permitted speed for the tires fitted could cause tire failure.fAlways check the maximum speed rating on the tire sidewall on any tire on the vehicle.fNever exceed the maximum speed rating of the tires.
Wheel change
fWhen wheels are removed, mark the direction of rotation and position of each wheel.Example: FR (front right), FL, RR and RL.fAlways fit the wheels in accordance with the markings.
Snow chains
Risk of damage to body, axle or brake components.fFit snow chains only to the rear wheels, and only with the tire/rim combination listed in the Technical Data.fUse only the fine-link snow chains recommended and authorized by Porsche so that sufficient clearance between the wheel well and the chain is assured.fPlease see the chapter “WHEELS, TIRES” on page 286.fFollow instructions issued by the supplier of the chains.

258 Minor Repairs
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.

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.
