Snow chains

Risk of damage to body, axle or brake components.

  • Use only the fine-link snow chains recommended and authorized by Porsche so that sufficient clearance between the wheel well and the chain is assured.
  • Please see the chapter "WHEELS, TIRES" on page 309.
  • Follow instructions issued by the supplier of the chains.

The best possible handling characteristics are achieved when snow chains are fitted on all four wheels of the vehicle. However, it is also possible to fit snow chains only on the rear axle.

  • Remove spacers if snow chains are mounted.
  • Before fitting chains, remove accumulated ice and snow from the wheel well.
  • Vehicles with snow chains must not be driven faster than 30 mph (50 km/h).

Different states and countries have varying statutory requirements regarding maximum speed.

  • Check with local authorities for possible restrictions.
  • Remove chains as soon as the roads are free of ice and snow.
