Tires: Testing and Inspection
WM 0X03IN Running gear maintenance: Tyres and spare wheel: checking condition and tyre pressure
Checking
Checking condition
For vehicles with tyre pressure monitoring (TPM), which can be identified by aluminium valves, the tyre pressure must be adjusted according to the ]] Filling information [[ on the multi-function display. To do this, select ]] Main menu ]] Tyre pressure ]] Filling information [[. Adjust the deviation values so that they range from 0.0 bar to +0.1 bar. Fill the tyres according to the display using the tyre-inflating device. Example: If the tyre pressure display ]] Filling information [[ shows - 0.2 bar, 0.2 bar pressure must be added.
Filling information
Information
The ]] Tyre pressure [[ display is for information purposes only.
- Tyre pressure settings can only be entered according to the values in ]] Filling information [[.
Due to the pressure and temperature relationship (approx. 0.1 bar/10°C), the actual pressures displayed under ]] Tyre pressure [[ on the multi-function display, or on the pressure gauge of the tyre-inflating device, can deviate from the required pressure specified at 20°C on the tyre pressure plate if the air temperature in the tyre is significantly above (higher values) or significantly below (lower values) 20°C. Changes in the tyre pressure are displayed after max. 1 minute in the ]] Filling information [[. A series of dashes (-.-) will appear instead of the tyre pressure during this time.
Tyre pressure
Always use plastic valve caps on vehicles with tyre pressure monitoring (TPM). Plastic valve caps protect against dust, dirt and humidity, and therefore against damage (corrosion).
Tyres 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 accidents if the air pressure in the tyres falls below the minimum, if the tread depth is insufficient or if there are foreign bodies, pricks, cracks and bulges in the sidewall (ply breakage).
- Modified handling behaviour can cause accidents and major material damage.
-> The air pressure must never fall below the values specified (these are minimum pressures).
-> The tread depth must never fall below the minimum value.
-> A visual inspection of the tyres (for cracks, pricks, bulges in the sidewall and/or foreign bodies) must be carried out.
1. Check condition and tyre pressure.
2. Always screw on valve caps tightly and replace missing valve caps.
Notes
Cold tyre pressures (at approx. 20° C)
Information
The currently applicable air pressure values and comfort tyre pressure values in the individual countries can be found in the Manufacturer Approval ]]Approved wheels and tyres[[ in the ]]Manufacturer Approvals[[, Group 4.
Tyre pressures apply to all-season, winter and summer tyres. They also apply only to tyres approved by Porsche.
Part load: The tyre pressure is specified for a load of up to 3 people + 21 kg of luggage.
The collapsible spare wheel is an optional extra (tyre sealant comes as standard).
