Replacing tires and wheels

  • Switch off the ignition when changing tires.

Lack of grip
Initially, new tires do not provide their full grip.

  • You should therefore drive at moderate speeds during the first 120 miles (200 km) to extend the service life of the tires and achieve full performance capability.

  • Only tires from the same manufacturer and with the same specification code (e.g. "N0," "N1," etc.) may be mounted on the vehicle.
  • Before mounting new tires, inquire about their current approval status: Contact an authorized Porsche dealer. e Use only tire makes tested and approved by Porsche.
  • The difference in tread depths on one axle must not exceed 30%.
  • Always replace both tires on one axle to avoid any unnecessary effect on driving behavior due to varying tread depths.
  • Only authorized Porsche dealers may install tires.
    Visit a qualified specialist workshop. Porsche recommends an authorized Porsche dealer, as they have trained technicians and the necessary parts and tools.
  • Adjust your driving style to the altered handling behavior.

Information
New wheels must have tire pressure sensors for the Tire Pressure Monitoring System (TPMS).


  • Make sure the wheels are compatible with the TPMS on your vehicle. For information on suitable wheels and on the TPMS on your vehicle: Contact an authorized Porsche dealer.
  • Check the battery level of the tire pressure sensors when changing tires.

Information
If new tires are installed only on one axle, a noticeable change in handling occurs due to the different tread depth of the other tires. This is especially the case if only the rear tires are replaced. The effect is reduced continuously, however, as tire mileage increases.


Check and replace valves and valve caps

  • Use only genuine Porsche valves for the Tire Pressure Monitoring System (TPMS).
  • Have the valves checked and replaced if necessary whenever the tires are changed.
    Porsche recommends an authorized Porsche dealer, as they have trained technicians and the necessary parts and tools.

In the absence of valve caps the valve is unprotected from dust and dirt, resulting in leaks.

  • Always screw on valve caps tightly to protect valve inserts from dirt. Dirty valve inserts can cause creeping air loss.
  • Replace missing valve caps immediately.
  • Use only plastic valve caps.


Using snow tires

Exceeding the maximum permitted speed
Exceeding the maximum permitted speed may cause tires to burst.

  • Observe the maximum permitted speed for the tires.
  • Snow tires with a lower maximum permitted speed than the given maximum permitted speed of the vehicle may only be installed if they bear the M+S designation on the tire sidewall. All-season and all-terrain tires also have speed limits and bear this designation.
  • Affix the sticker with the maximum permitted speed in the driver's field of vision. Observe country-specific regulations.
  • Set the maximum permitted speed as the speed limit using the multifunction display:
  1. Please see chapter "Adjusting the speed limit" on page 170.

  • Install snow tires in a timely manner before the cold season begins.
  • Snow tires should have the same load capacity as original equipment tires and should be mounted on all four wheels.
  • Use only tire makes tested and approved by Porsche.
  • Before mounting new tires, inquire about their current approval status: Contact an authorized Porsche dealer.
