Wheels, tyres: visual inspection for damage

Check tyres for sufficient tread depth, foreign bodies, pricks, cracks and bulges in the sidewall (ply breakage).
Check age of the tyres. Replace tyres if necessary.

Checking wheel mounting

Use suitable commercially available tools (wrench size 19 mm) together with a tested torque wrench, covering
the range up to 130 Nm (96 ftlb.). Never use an impact bolter.
Do not undo the wheel bolts to check whether they are secure. Tighten the wheel bolts to 130 Nm (96 ftlb.)
and check that they fit securely.

Tyre pressure for cold tyres (approx. 20 °C)

DANGER

Tyre damage due to insufficient tyre pressure in conjunction with driving at high speeds, due to tyres
that are too old and/or tyres which do not meet Porsche requirements.

Increased risk of accidents.

• 

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

minimum pressure.

→ Carry out a visual inspection and check tyre age. Replace tyres older than 6 years .

→ Use only tyres recommended by Porsche.

Note

Valve caps protect the valve from dust and dirt and therefore from leaks! Always screw caps tight and
replace any missing caps.

characters N1, N2, N3 or N0 distinguish the summer tyres specially authorised by Porsche from other models
of the same tyre type and size!

Notes on mounting tyres

When fitting tyres, the direction of rotation and the inner and outer sides should be noted!

• 

If there are no mounting instructions on the tyre sidewall, the tyre must be mounted so that the DOT
code is visible from the outside.

Wird der Fehler nicht bemerkt, besteht die Gefahr, daß Arbeiten nicht korrekt
durchgeführt werden und es dadurch zu Personen- und Sachschäden kommt.

WARNING

Danger of losing text-figure correspondence when printing out.

For technical reasons, it can currently not be ruled out that the correspondence
between text and associated figure can be lost when it is printed out, even though
the display on the screen is correct.

• 

If the fault is not noticed, there is the danger that work will not be performed
correctly which can cause injury and damage.

• 

→ Therefore, always compare printouts with the screen display after printing them out. Correct
the printouts if they are faulty so that the content of the screen display matches that on the
printouts.

AVERTISSEMENT

Risque de perte de la correspondance texte-illustration lors de l'impression papier.

Pour des raisons techniques, il ne peut pas être exclu à l'heure actuelle que, même
en cas d'affichage correct à l'écran, la correspondance entre le texte et l'illustration
puisse être erronée sur l'impression papier.

• 

Si l'erreur passe inaperçue, on court le risque d'exécuter certaines opérations de
manière incorrecte pouvant conduire à des dommages corporels et matériels.

• 

→ Comparez impérativement pour cette raison les impressions papier avec l'affichage à l'écran.
Corrigez-les en cas d'erreur de manière à reproduire correctement l'affichage à l'écran.
