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 1208, then the tire was produced in the 12th week of 2008.


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.

Information
We recommend fitting winter tires on the vehicle at temperatures below 45 °F (7 °C) since the driving performance of summer tires is reduced at low temperatures. Summer tires may be permanently damaged at extremely low temperatures.

Winter tires do not fulfill their purpose if the tread depth is less than 5/32 in. (4 mm).

Comply with all state and local laws governing snow tire and tread depth requirements.

Excessive Speed for Tires

Exceeding the maximum permitted speed for the tires fitted could cause tire failure.

  • Always check the maximum speed rating on the tire sidewall on any tire on the vehicle.
  • Never exceed the maximum speed rating of the tires.

Wheel change

  • When wheels are removed, mark the direction of rotation and position of each wheel.
    Example: FR (front right), FL, RR and RL.
  • Always fit the wheels in accordance with the markings.
