Approved Winter Tires, Wheels and Snow ChainsINFORMATION: This list of approved products replaces Technical INFORMATION: No. 13/07 dated August 17, 2007.
Vehicle Type:
911 Carrera (997)/911 Carrera S (997)/911 Cabrio (997)/911 Cabrio S (997)
Model Year:
As of 2005 up to 2008
Situation:
Approved winter tire makes and types - June 2007
WARNING:
Mixed tires.
- Mixed tires result in uncontrollable vehicle handling.
- Only tires of identical type and make and with the identical speed index and specification code (NO, N1, N2....) can be used on the same vehicle.
Makes/Types:
INFORMATION:
- N... - Specification code of the tire, e.g. "NO", "N1", "N2"... The complete "N..." code of the tires in question must be shown on the tire sidewall near the tire type designation.
- Instructions for correct mounting of the tires are also given on the tire sidewall. If there are no mounting instructions on the tire sidewall, the tire must be mounted so that the DOT marking is visible from the outside.
Arrow with inscription "Rotation" = directional mounting.
"Inside/Outside" inscription = mounting on specified side only.
Arrow with both inscriptions "Rotation" and "Inside/Outside" = directional mounting on specified side only.
DANGER:
Tire pressure is too low and/or from insufficient maintenance.
- Increased risk of accidents
- The tire pressure must never fall below the tire pressure indicated below.
- Check tires at regular intervals for uniform profile wear and possible damage such as cracks, bulges, detachments in the running surface, penetration from foreign objects, etc.
- Tires older than 6 years are to be replaced.
- Never use solvents or other chemical substances on tires (e.g. for cleaning or dying).
- Replace tire valve at every tire change.
If a tire is damaged and it is not possible to determine with absolute certainty that there is no ply damage - with all of its consequences - or if the tire was thermally and/or mechanically overloaded due to a loss of pressure or other prior damage, we recommend that you replace the tire in question for safety reasons.
Repairs on "V", "W", "Y" and "ZR" tires should also be avoided, as well as the use of inner tubes in tubeless tires. Please inform your customers accordingly.
Tire Pressure:
INFORMATION: The tire pressure applies only to the tire makes and types approved by Porsche, and is specified for cold tires (approx. 68 ° F/20 °C. The tire pressures must never be lower than the specified values.
Sizes:
Permissible winter tire and wheel sizes. RO - rim offset in mm.
CAUTION:
Damage to wheel surface.
- Risk of surface damage if the tires/valves are not mounted according to equipment operating instructions, and/or if the wheel surface is not cleaned/cared for correctly.
- Carry out tire removal and mounting with a bead holding-down device only.
- Use a leather pad on the rim flange to support the valve insertion tool.
- Use only the Porsche centering clamping set for balancing.
- Do not clean the wheels with brushes (car wash or washing car by hand). Deep scratches in the surface coating of the wheel cannot be repaired by polishing.
Wheels:
INFORMATION: The 8Jxl9 H2 wheel, RO 57, part no. 997.362.156.00 can not be installed on vehicles with PCCB.

Identification on the inside/outside of the wheel disc:
Wheel size, rim offset (RO) in mm, Part No. and Porsche logo

Snow Chains
DANGER:
Incorrectly fitted snow chains.
- Uncontrollable vehicle handling and increased risk of accidents.
- Observe fitting instructions from the chain manufacturer.
- Do not exceed the maximum speed of 30mph km/h (50).
INFORMATION: Sufficient snow-chain clearance is only possible by first removing any spacers that are installed.
Porsche offers the following snow chains as accessories:
Navigation Systems
After a wheel or tire change, the full locating accuracy is attained only after a trip of approx. 50 km (30 miles), if possible on a highway and at a speed > 60 km/h (40 mph). Furthermore, a high wheel slip factor (e.g. wheel spin) can result in temporary incorrect positioning.
TPM Tire Pressure Monitoring System
New wheels must be equipped with wheel transmitters for Tire Pressure Monitoring.
Check battery charge status of wheel transmitters before changing tires.
Switch off ignition when changing a wheel.
If the properties of the new tires do not correspond to the settings in the on-board computer, a message is displayed.
After changing a wheel, the tire settings in the on-board computer need to be updated (see operating instructions).
Wheel Storage:
Tires must be stored in a cool, dry and dark room with adequate ventilation. Tires must never come into contact with fuel, oil, grease or chemicals.
Complete wheels can be stacked for storage; we recommend that you increase the tire pressure by approx. 0.4bar(6psi).
Optimum conditions for storage of the complete wheels are provided by the Original Porsche storage trolley, Part No. 000.044.000.38.
If the tires are not mounted on wheels, it is best to store them in a vertical position. We recommend that you turn tires stored in this position every two weeks in order to prevent flat spots. Tires that are stacked in a horizontal position will become severely deformed and cannot be seated properly in the rim flange when they are mounted.
