Example of a tire pressure plate ATire Pressure plateDepending on when your vehicle was manufac-
tured, the tire pressure plate on the driver's door
will contain different data.
Information on the tire pressure plate A
A Seating capacity
Maximum number of vehicle occupants, includ-
ing the driver.B Vehicle load limit
Is the maximum total weight limit specified of
the load (passengers and cargo) for the vehi-
cle. This is the maximum weight of passengers
and cargo that can be loaded into the vehicle.
If a trailer is being towed, the trailer tongue
weight must be included as part of the cargo
load. Please observe the chapter “LOADING
INFORMATION” on Page 213.
C Original tire size
Size of tires mounted at the factory.
D Recommended cold tire inflation pressure
These values are for cold tires (68°F/20 °C).
E Approved tire sizes
F Size and tire pressure for the collapsible spare
wheel

Example of InscriptionInscription on radial tireATire size
Example: P 255/55R18 109 Y
–P - The tire is designed for Passenger vehicle.
This information is not included on all tires.
–255 - Indication of tire width in mm
–55 - Indication of tire height to tire width ratio
in percent
–R - Belt type code letter for radial–18 - Indication of rim diameter in inches
–109 - Load capacity coefficient
–Y - Speed code letter
B TIN (Tire Identification Number)
Example: DOT xx xx xxxx xxxx
–DOT
The DOT symbol indicates that the tires com-
ply with the requirements of the US Depart-
ment of Transportation and provides informa-
tion about:
– first two-digit code means manufacture’s iden-
tification mark.
– second two-digit code means tire size.
– third four-digit code means tire type code.
– fourth four-digit code means date of manufac-
ture.
If, for example, the last four numbers read
1204, the tire was produced in the 12th week
of 2004.
C Tire ply composition and material
The number of layers in the tread and sidewalls
and their material composition.
D Maximum permissible inflation pressure
The maximum permissible cold inflation pressure
to which a tire can be inflated.
fDo not exceed the permissible inflation pres-
sure.
E Maximum Load rating
The maximum load in kilograms and pounds can
be carried by the tire. If you replace tires always
use a tire that has the same maximum load rating
as the factory installed tire.
F Term of tubeless or tube tire
Identification for tubeless tires.
GRadial
The identification indicates if the tire has radial
structure.

Spare wheel
Warning!
Risk of accident. The wheel and tire size and
the tire quality of the spare wheel and normal
wheel may differ.
If a spare wheel that differs from the normal
tires is used, this may impair the driving
behavior.
fThe spare wheel must be used only over short
distances in cases of emergency.
For safety reasons, replace the tires before
the wear indicators appear (webs in the tire
grooves, 1/16 in. (1.6 mm) high).
fNever deactivate the Porsche Stability
Management (PSM) system.
fIf the tire on the spare wheel is older than
4 years, the spare wheel should be used only
in the event of a flat.
fAvoid hard acceleration and high cornering
speeds.
The maximum permitted speed is 50 mph
(80 km/h) if the mounted spare wheel differs
from the other three wheels on the car. This
maximum speed must not be exceeded
because of altered driving characteristics and
for reasons of wear.
fDo not use a spare wheel from a different vehi-
cle type.
fDo not mount the spare wheel from your car on a different vehicle.Removing spare wheel
Warning!
Danger of injury if the spare wheel is
removed improperly.
fRemove the spare wheel only when the spare
wheel bracket is locked.
fRemove the spare wheel from the spare wheel
bracket with care. The wheel is very heavy [approx. 77 lbs. (35 kg)].
1. Unscrew all five wheel bolts.
2. Remove the top wheel bolt.
Remove assembly aid from the tool kit and
screw in instead of the wheel bolt.
Remove the remaining wheel bolts.
Fitting spare wheel
fInsert wheel bolts and tighten by hand.
Remove assembly aid and screw in remaining
wheel bolt.
Initially tighten bolts in diagonally opposite
sequence so that the wheel is centerd.
fPlease observe the chapter “TIRE PRES-
SURES, COLD” on Page 385.
fAfter mounting the wheel, tighten all five wheel
bolts to 111 ftlb. (150 Nm).

Cayenne and Cayenne SThe load capacity coefficient (e.g. “106”) and maximum speed code letter (e.g. “T”) for permitted top
speed are minimum requirements.
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.
