Notes regarding Pirelli P-ZERO tires N1 and N2:
Pirelli P-ZERO tires (Asimmetrico N1, Direzionale N2 and Asimmetrico N2) have two different tire designs. Combinations of N1 and N2 are not allowed. If installing Pirelli P-ZERO N2 tires, use only on the following axles:
Direzionale N2 = front axle installation only
Asimmetrico N2 = rear axle installation only
Tire Pressure:
16" and 17" Wheels Emergency Spare
Front Axle 2.0 bar (29 psi) 4.2 bar (60 psi)
Rear Axle 2.5 bar (36 psi) 4.2 bar (60 psi)
The above fill pressures are valid only for Porsche approved tires measured while cold (approximately 20 degrees Celsius). The measured tire pressures must never fall below those given above.

Overview of Porsche Rims for Summer Tires
The rim description is located on the inner or outer rim face (i.e.; wheel size, offset (ET), part number and Porsche trademark).
Information:
- At each tire change a new rubber valve stem (part number, 900.265.001.50 or 000.044.600.00 - including cap) must be installed.
- During installation the notes on the tire sidewall regarding uni- or side-directional installation must be observed.
- Coat the tire bead and rim humps with assembly paste so that the bead easily glides over the hump. To avoid rotation of the new tire on its rim, hard acceleration or braking is to be avoided for the first 100 to 200 miles of driving.
- During tire mounting the pressure in the tire should not exceed 4.0 bar (58 psi).
- When replacing a single tire on an axle, the difference in tread depth may not exceed 30%.
- Repairs to "ZR" rated tires are unreliable. Porsche recommends replacing damaged tires.
- Tires age from chemical and physical processes which can affect their function. Tires which are not driven for long periods of time harden and deteriorate faster than tires which are in continuous use. For this reason tires should be evaluated for both tread depth and aging. TIRES SHOULD NOT BE OLDER THAN 6 YEARS (including the spare). The tire age can be determined from the DOT description on the sidewall, which indicates the production date of the tire for (example. : DOT 066... < = 6th week of 1996).
- The storage area for tires must be cool, dry, dark, and ventilated. Tires can never come in contact with gasoline, oils, grease, or other chemicals.
- Complete tire / wheel assemblies can be stored horizontally. It is recommended that they be inflated 0.4 bar above the recommended pressure.
- Unmounted tires are best stored in a vertical position. When storing tires in a vertical position, it is recommended to rotate the tires every 2 weeks to prevent any flat spots from developing. When unmounted tires are stored horizontally, they deform severely and will be difficult to mount on the rim flange.
- Optimal conditions for tire / rim assembly storage are offered by the Original Porsche Transport Carrier, part. number, 000.044.000.22.
- Installation of 18 inch wheels is not approved by Porsche.
