Minor Repairs
Tire damage, puncturefPlease see the chapter “HIGH-PRESSURE
CLEANING EQUIPMENT, STEAM CLEANERS”
on Page 271.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires.
fCheck tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
fAfter driving off road, examine tires for signs
of damage such as cuts, tears, bulges or
foreign objects stuck in the tread. Replace a
damaged tire if necessary.
fCross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
fIn cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.In case of tire damage, where it is uncertain
whether there is a break in the ply with all its con-
sequences or tire damage caused by thermal or
mechanical overloading due to loss of pressure or
any other prior damage, we recommend that the
tire be replaced for safety reasons.
I f o n e f a u l t y t i re i s re p l a c e d i t s h o u l d b e n o t e d t h a t
the difference in tread depth on one axle must not
exceed 30%. Handling inconsistencies may result.
fPerform a visual inspection if necessary.
Tire replacementsfUse only tire makes and types tested by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same manufacturer and
with the same specification code (e.g. “N0”,
“N1”...) should be mounted on the vehicle.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Tires should be replaced no less than on one axle
at the time. Only tires of the same make and type
must be used. Mixed tires are not permissible and
will affect vehicle performance, safety, and can
affect vehicle warranty.Porsche dealers can recommend the most current
replacement tire options for your vehicle.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km).
Tires must always remain on the same side of
the vehicle.
When wheels are removed, the direction of rota-
tion and position of each wheel should be marked.
If new tires are installed only on one axle, a notice-
able change in handling occurs due to the different
tread depth of the other tires. This happens espe-
cially if only rear tires are replaced. However, this
condition disappears as the new tires are broken
in.
fPlease adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
fUse only plastic valve caps.
fThe rubber valves must be replaced whenever
the tires are changed.
fThe fitting and replacement specifications
must be observed for metal valves.
fOnly use Original Porsche metal valves.
fProtect the valve inserts against soiling with
valve caps.
Soiled valve inserts can cause a gradual loss
of air.

Snow chains
Warning!
Risk of damage to body, axle or brake com-
ponents.
fUse only the fine-link snow chains recommen-
ded and authorized by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
fPlease see the chapter “TIRES, RIMS, TRACKS”
on Page 350.
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
before 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 see the chapter “SPACERS” on
Page 293.
Please see the chapter “CHANGING A WHEEL
WITH REMOVAL OF 17 MM SPACER” on
Page 303.
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.
