Official Porsche Winter Tires Recommendations for 2004/2005
265/40 R18 97V M+S (rear)
Continental Winter Contact TS 810 N0
This combo is recommended for snow and dry/wet pavement.
235/35 R19 87V M+S (front)

295/30 R19 100V SL M+S (rear)
Pirelli Winter 240 SnowSport N0
This combo is recommended for snow and dry/wet pavement.
Recommended tire pressure:
18'': 2.5 bar (front) and 3.0 bar (rear)
19'': 2.5 bar (front) and 3.0 bar (rear)
These are the recommended tire pressures for a fully loaded car but we recommend them anyway for a less loaded car too because the standard recommended tire pressure refers to a car loaded to two persons without luggage only.
It is not approved and very likely not possible to mount snow chains on the 19'' wheels!!!
Approved rims:
18'' Carrera III rim
19'' Carrera S rim
19'' Sport Design rim
19'' Carrera Classic rim
Porsche offers snow chains which are fully compatible to the 18'' wheel combos, part nunber is: 997.044.600.07.
The Porsche snow chain is approved for the rear tires (265s) only. Max. speed with snow chains: 50 kph (30 mph).
We do not recommend "swapping" of tires (exchanging summer tires with winter tires and back again on the same rim) due to possible damage in the mounting/de-mounting process, damage which might not be visible.
