Checking Condition

tires are a safety element that fulfil the demands placed on them only if they have the correct air pressure and a sufficient tread depth.

→ Adjust the Tire pressure according to specifications. Never allow the pressure to fall below the minimum pressure.

→ Check age of tires. Replace tires that are more than 6 years old.

→ Perform visual inspections.

→ Use new rubber valves at every Tire change.

→ Use only tires recommended by Porsche.

Information 

• The Tire pressure was changed in model year 2006  . → WM 030000 CHECKING LID AND DOORS (EXCEPT CAYENNE DIESEL, CAYENNE TRANSSYBERIA S, CAYENNE TRANSSYBERIA MAN, CAYENNE GTS TIP "PORSCHE DESIGN EDITION 3")
• For vehicles with Tire Pressure Monitoring (TPM) - identified by aluminium valves, the Tire pressure should be adjusted according to the filling information in the multi-function display. To do this, select >> Main menu >> Tire pressure >> -Settings- << and adjust the deviation values so that they range 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 >> Settings << = -0.2 bar, 0.2 bar must be added  .

• Due to the pressure and temperature relationship (0.1 bar/10° C), the actual pressures displayed on the -Basic Tire pressure screen- in the multi-function display, or on the pressure gauge of the Tire-inflating device may deviate from the required pressure specified at 20° C on the Tire pressure plate, if the air temperature in the Tire is significantly above (higher values) or significantly below (lower values) 20° C. Changes in the Tire pressure are displayed up to a max. of 1 minute later in the >> Settings <<.

• For vehicles with Tire Pressure Monitoring (TPM), always use plastic valve caps. They protect the valve from dust, dirt and moisture and therefore from damage (corrosion, etc.). 

1. checking condition and Tire 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.
