Tires: Testing and Inspection
Wheels and tiresChecking condition
Tires are a safety element that fulfill the demands placed on them only if they have the correct air pressure and a sufficient tread depth.
WARNING:
Risk of change in handling behavior if tire pressures fall below minimum values. Change in handling behavior if insufficient tread depth or foreign bodies, pricks, cracks and bulges in the sidewall (ply breakage).
^ Injury and material damage possible.
^ The air pressure must never fall below the values specified (these are minimum pressures).
^ A visual inspection of the tires must be carried out.
Note:
^ For vehicles with a tire pressure monitoring system, identified by the aluminum valves, the tire pressure should be adjusted according to the filling information in the multi-function display. To do this, in >> Main menu >> Tire pressure >> - Adjustments << adjust the difference values so that they are from 0.0 bar to +0.1 bar. Fill the tires according to the display using the tire-inflating device. Example: If the tire-pressure display shows >> Adjustments << - 0.2 bar, 0.2 bar pressure must be added.
^ Due to the pressure and temperature relationship (0.1 bar/10°C), the actual pressures displayed in the - Basic tire pressure screen in the multi-function display, or on the pressure gauge of the tire-inflating device, can deviate from the required pressure specified at 20°C on the tire pressure plate: if the tire air temperature is significantly above (higher values) or significantly below (lower values) 20°C. Changes in tire pressure are displayed after a maximum delay of one minute in the >> Adjustments <<.
^ For vehicles with the tire pressure monitoring system, always use plastic valve caps. They protect the valve from dust, dirt, and moisture and therefore from damage (corrosion, etc.).
1. Check condition and tire pressures.
Valve caps protect the valve from dust and dirt and therefore from damage.
2. Always screw on valve caps tightly and replace missing valve caps.
Cold tire pressures (at approximately 20°C)
Tire pressures apply to all-season, all-terrain, summer and winter tires.
They also apply only to tires approved by Porsche.
Partial load: The tire pressure is specified for a load of up to 3 people + 21 kg of luggage.
The collapsible spare wheel, or alternatively the spare wheel, is an option (standard: tire sealant)
The spare wheel on the carrier is inflated to 3.4 bar gauge pressure max. During operation, tires are to be adjusted to the gauge pressure specified for the particular vehicle axle and load condition.

Overview of tires and wheels (standard)
^ The chart of tires and wheels for summer and winter should be taken from Technical Information (TI) Group 4.
^ When replacing summer tires, pay close attention to the tire specification number. The specification characters N1, N2, N3 and N0 distinguish the summer tires specially authorized by Porsche from other models of the same tire type and size.

Note:
^ When mounting the wheel on the vehicle, observe the mounting specifications of the wheel bolts.
Notes on mounting tires
^ When fitting tires, the direction of rotation and the inner and outer sides should be noted.
