Tires/Wheels - Approved Winter Wheels/Tires/Spacers
01/07 ENU 4440Approved Tires, Wheels and Spacers
Note
This list of approved products replaces Technical Information No.1/07 dated April 9, 2007.
Vehicle Types:
Cayenne/Cayenne S/Cayenne Turbo
Model Year:
As of 2008
Situation:
Current winter tire approvals - approval status July 2007.
WARNING:
Mixed tire.
Note
"N..." = Specification code of the tyre, 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. Only tires of the same make and type, with the same speed index and the same specification code may be used on a vehicle.
The tire makes and types tested and approved by Porsche are only "XL" (Extra Load) tires. Instructions for correct mounting of the tires are also given on the tire sidewall.
Arrow with inscription "Rotation" = directional mounting.
"Inside/Outside" inscription = mounting on specified side only.
Arrow with both inscriptions "Rotation" and = directional mounting on specified side only.
"Inside/Outside"
Note:
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, replace the tire in question for safety reasons.
Repairs must not be carried out on "V", "W", "Y" and "ZR" tires and inner tubes must not be used in tubeless tires. Please advise your customers accordingly.
If temperatures fall to below 45° F./7°C we recommend that you always fit winter tires on the vehicle because the vehicle handling features of summer tires are not as good at low temperatures. Extremely low temperatures can cause permanent damage to summer tires.
Note
The tire makes and types shown in bold in the tables below are newly approved makes and types. We recommend that only newly approved tires are used when mounting new tires.
Winter Tires:
Winter tires are generally designed for use in the low temperature range and offer distinct advantages for winter-time road conditions, such as snow-covered and icy roads, compared with all-season tires. Specially developed tread compositions and tread patterns have provided targeted improvements in winter properties whilst maintaining safe handling on wet and dry roads.
All-Season Tires:
Targeted optimization of the tire compositions and treads has produced a good compromise between the driving characteristics at summer temperatures and driving safety on snow and ice.
The all-season tires approved for the Cayenne feature an M+S identification and are suitable for winter driving.
Summer Tires:
Tire Pressure:
Tire pressure is too low and/or from improper maintenance. Increased risk of accidents.
Observe the tire pressure indicated below.
--> Check tires at regular intervals for uniform tread wear and possible damage such as cracks, bulges, detachments in the running surface, penetration from foreign objects, etc.
--> On vehicles without tire pressure monitoring system: Use new rubber valves at every tire change.

Wheels:
Overview of Porsche wheels for summer, winter and all-season tires
Identification on the inside/outside of the wheel disc:
wheel size, rim offset (RO) in mm, order and part number, and Porsche logo (the order number is not shown on the part).
Snow Chains:
DANGER!
Incorrectly mounted snow chains.
Wheel Mounting:
Tightening torque 160 Nm (118 ftlb.)
Removing/mounting:
Before mounting or removing a wheel, screw the assembly aids (threaded bolts for wheel mounting, Part No. WHT.001 .963) into the wheel hub instead of the two wheel bolts. Only then should you remove the three remaining wheel bolts and remove the wheel carefully, without touching the brake discs. The wheels are secured with standard wheel bolts (M14 x 1.5 x 51), Part No. 955.361.203.01. Never grease the wheel bolts. Only 'original Cayenne wheel bolts' may be used!
Screw in wheel bolts by hand and then tighten evenly in diagonally opposite sequence. Start at the top when tightening.
Navigation Systems
After a wheel or tire change, the full locating accuracy is attained only after a trip of approx. 30 miles (50 km), if possible on a highway and at a speed > 40 mph (60 km/h). Additionally, a high wheel slip factor (e.g. wheel spin on snow) 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).
General:
Always use new valves when changing tires.
