Practical Tips, Minor Repairs
Tire pressures
Danger!
Risk of accident.
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 and cause damage. Always use an
accurate tire pressure gauge when checking
inflation pressures.
fDo not exceed the maximum tire pressure
listed on the tire sidewall. (Also refer to “Tech-
nical data“).
fCold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
68°F (20°C), when adjusting the inflation pres-
sure. Avoid sunlight striking the tires before
measuring cold pressures, since the pressures
would rise from temperature influence.
fValve caps protect the valve from dust and dirt,
and thus from leakage. Always screw caps
tightly down. Replace missing caps immedi-
ately.
fFor safety reasons, don't use tire inflating bot-tles.The tire pressure must match the prescribed
value.
You can find information on the tire pressure:
– In the front left door aperture.
– Please observe the chapter “TIRE
PRESSURES, COLD” on Page 350.
These values are for cold tires (68°F/20 °C).
fCheck the tire pressure at least every
2 weeks. Always check when tires are cold.
fOn vehicles with tire pressure monitoring
system:
Please observe the chapter “TIRE PRESSURE”
on Page 85.
When tires are warm, the tire pressure is
increased.
fNever let air out of hot tires. This could cause
the tire pressure to fall below the prescribed
value.
Insufficient tire pressure can cause tires to
overheat and thus be damaged – even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting the tire pressure.Overloading
Danger!
Risk of personal injury, loss of control and
damage to vehicle parts.
fDo not overload your vehicle. Be careful about
the roof load.
fIf loading the vehicle also correct the tire pres-
sure. Tire pressure for loaded vehicle can be
found on the tire pressure plate and in the
chapter technical data.
fNever exceed the specified axle load.
Overloading can shorten the service life of the
tires and car, as well as lead to dangerous vehi-
cle reactions and long braking distances.
Damage due to overloading is not covered by the vehicle warranty.
fPlease observe the chapter “LOADING INFOR-
MATION” on Page 191.
fPlease observe the chapter “TIRE PRESSU-
RES, COLD” on Page 350.

1)Snow chainsSnow chain clearance can be guaranteed only with the tire + rim combination marked
1).
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).
For safety reasons, vehicles with snow chains must not be driven faster than 30 mph (50 km/h).
fObserve the respective road traffic regulations.
fUse only Porsche-authorized fine-link cross-type or edge chains.
