Practical Tips, Minor Repairs
Snow chains
Warning!
Risk of damage to body, axle or brake com-
ponents.
fUse only the fine-link snow chains recom-
mended and authorized by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
fFollow 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 on only one axle (preferably the
rear axle).
fRemove spacers if 18 inch tires, snow chains
or a collapsible spare wheel are mounted.
Caution!
Risk of damage to wheel housings if the
spacers on the rear axle are not removed be-
fore fitting the snow chains.
f17 mm spacers must always be removed from the rear axle when snow chains are to be fitted.
fFor information on the spacers:
Please observe the chapter “SPACERS” on
Page 314.
For information about removing the spacers:
Please observe the chapter “CHANGING A
WHEEL WITH REMOVAL OF 17 MM SPACER”
on Page 323.
fBefore fitting chains, remove accumulated ice
and snow from the wheel well.
fVehicles with snow chains must not be driven
faster than 30 mph (50 km/h).
Different states and countries have varying statu-
tory requirements regarding maximum speed.
fCheck with local authorities for possible
restrictions.
fRemove chains as soon as the roads are free
of ice and snow.

Practical Tips, Minor Repairs
SpacersfUse the spacers only together with wheels
approved by Porsche.
Before having spacers fitted, find out about the
current approval status.
fRemove spacers if 18 inch tires, snow chains
or a collapsible spare wheel are mounted.
Danger!
Risk of accident if the spacers are not re-
moved before mounting 18 inch tires or col-
lapsible spare wheel.
f17 mm spacers are always to be removed be-
fore mounting 18 inch tires or a collapsible
spare wheel, because the wheel cannot be fit-ted correctly. Caution!
Risk of damage to wheel housings if the
spacers on the rear axle are not removed be-
fore fitting the snow chains.
f17 mm spacers must always be removed from the rear axle when snow chains are to be fitted.Note on operation
fTo remove or mount the spacers:
Please observe the chapter “CHANGING A
WHEEL WITH REMOVAL OF 17 MM SPACER”
on Page 323.
Please observe the chapter “FITTING THE

When fitting new tires or changing tires: Please observe the chapter “TIRES/WHEELS” on Page 297.Tire and rim sizes
Extensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche
dealer has information about approved tires and wheels and is happy to assist you.
If aftermarket tires and/or wheels are installed which are not approved by Porsche, the vehicle’s roada-
bility and handling characteristics might be impaired. Since Porsche has no data on such combinations,
Porsche cannot stand behind the safety or durability of these aftermarket combinations.
Please observe the chapter “SNOW CHAINS” on Page 308.
