Wheels with Tire Pressure Monitoring System (TPMS) sensors

  • Before changing wheels, make sure that the wheels are compatible with your vehicle's TPMS. Check this with your authorized Porsche dealer.

Removing and storing tires

  • After changing, adjust tire pressure and torque wheel bolts diagonally.
    Please see the chapter "CHANGING WHEELS" on page 301.
  • Store tires in a cool and dry place. Rotate periodically to avoid flat spots.
  • Do not store summer tires or park vehicles fitted with summer tires at ambient temperatures below 5 °F (-15 °C).
  • Avoid contact with fuel, oil and grease.

Tires must always remain on the same side of the vehicle.
When wheels are removed, the direction of rotation and position of each wheel should be marked.

Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with their marking.

The perception that tire durability and performance are not affected by storage and age is unfounded.

Chemical additives, which make the rubber elastic, lose their effectiveness over the course of time and the rubber becomes brittle and cracks.

Therefore, the tires should be inspected from time to time.

Information
Under no circumstances should tires older than 6 years be used on your Porsche.

The age of the tire can be obtained from the "DOT" code number. If, for example, the last four numbers read 1211, then the tire was produced in the 12th week of 2011.


Snow tires
The installation of Porsche approved snow tires is recommended.

Use Porsche approved snow tires for grip on snow and ice.

Check with your local Motor Vehicle Bureau for possible restrictions.

Snow Tire Use
The standard tires profile and rubber mixture are optimized for wet and dry driving conditions, and may not prove favorable for snow conditions.

  • Install snow tires before driving in such conditions.


Risk of insufficient road grip leading to loss of control and damage to the vehicle.

The standard tires profile and rubber mixture are optimized for wet and dry driving conditions, and may not prove favorable for snow conditions.

  • Install snow tires before driving in such conditions.

Before mounting snow tires, consult with your Porsche dealer. They have the technical information necessary to advise you on wheel and tire compatibility.

  • Snow tires should have the same load capacity as original equipment tires and should be mounted on all four wheels.

Tire Hazards
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases the rate of wear of the affected tires and causes damage.

Tires with badly worn treads are very dangerous and could cause accidents.

  • Make sure they are replaced immediately.


  • Do not exceed the snow tire speed rating.

Snow tires do not have the same degree of traction on dry, wet or snowfree roads as normal tires.

Furthermore, snow tires wear rapidly under these conditions.
