Wheels and tyres/tyre pressure

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 of cold tyres (approx. 20° C) - Boxster and Cayman

WARNING

Incorrect tyre pressure

- Uncontrollable vehicle handling

-> Adjust the tyre pressure according to specifications. Never allow the pressure to fall below the minimum pressure.
-> Check age of tyres. Replace tyres that are more than 6 years old.
-> Perform visual inspections.
-> Use new rubber valves at every tyre change.
-> Use only tyres recommended by Porsche.

Information

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

Boxster and Cayman - up to model year 2008 (summer and winter tyres)









Boxster and Cayman - from model year 2009 onwards (summer and winter tyres)

- Spare wheel/collapsible wheel not available! However there is a tire repair kit in the luggage compartment which can be used to repair the damaged tire in the event of damage!
- For repairs in the event of damage, always observe the safety and operating instructions!

The chart of tyres and wheels for summer and winter should be taken from Technical Information (TI) Group 4!

When replacing summer tyres, pay close attention to the tyre specification number! The specification 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.
