Tires: Testing and Inspection
WM 0X03IN Running gear maintenance: Tyres and spare wheel: checking condition and tyre pressure
Checking
Checking condition
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.
Information
- The tyre pressure was changed in model year 2006. -> 030000 Running gear maintenance: Tyres and spare wheel: checking condition and tyre pressure - section on "Information"
- For vehicles with Tire Pressure Monitoring, which can be identified by aluminium valves, the tyre pressure should be adjusted according to the filling information in the multi-function display. To do this, select ]] Main menu ]] Tyre pressure ]] -Settings- [[ and 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 shows ]] Settings [[ = -0.2 bar, 0.2 bar must be added.
Tire Pressure Monitoring (TPM) control unit
- Due to the pressure and temperature relationship (0.1 bar/10° C), the actual pressures displayed in the -Basic tyre pressure screen- in the multi-function display, or on the pressure gauge of the tyre-inflating device, can deviate from the required pressure specification on the tyre pressure plate, which is defined at 20° C. This is particularly the case if the tyre air temperature is significantly above (higher values) or significantly below (lower values) 20° C. Changes in the tyre pressure are displayed up to a max. of 1 minute later in the ]] Settings [[.
Tire Pressure Monitoring (TPM) control unit
- For vehicles with Tire Pressure Monitoring, always use plastic valve caps. Valve caps protect against dust, dirt and humidity, and therefore against damage (corrosion).
1. Check condition and tyre pressure.
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.
Information
Cold tyre pressures (at approx. 20° C)
Tyre pressures apply to all-season, all-terrain, winter and summer tyres. They also apply only to tyres approved by Porsche.
The tyre pressure specifications Comfort vehicle with partial load/full load applies to all vehicles as of VIN: WP1ZZZ0PZ6LA08064. In this case, all-season, winter and all-terrain tyres have the same air pressure. Summer tyres are handled separately in the table.
Partial load: The tyre 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: tyre sealant)
The spare wheel on the carrier is inflated to max. 3.4 bar gauge pressure. During operation, tyres must be adjusted to the gauge pressure specified for the particular vehicle axle and load condition.
