Tires/Wheels The original equipment tires and wheel rims on
your Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.
For your safety remember the following:
– Wheel rims and wheel bolts are matched to fit
your Porsche.
– If you intend to use other than original equip- ment wheels, be sure that they conform to
Porsche specifications for your model.
Only tires with the same make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
– The use of wheel rims and wheel bolts that do not meet specifications of the original factory
installed equipment will affect the safe opera-
tion of your vehicle.
– Before you plan on exchanging wheels, or snow tires already mounted on the wheel rims,
consult your authorized Porsche dealer. Your
dealer has the technical information necessary
to advise you which wheel rims and wheel bolts
are compatible with the original factory instal-
lations.
Danger!
Risk of loss of contro l and serious personal
injury or death.
f If while driving, your vehicle experiences a sud-
den vibration or ride disturbance, and/or you
suspect that possible damage to your tires or
vehicle has occurred, you should immediately
reduce your speed without excessive use of
the brakes.
f Stop the vehicle as soon as possible, and in-
spect the tires.
If you cannot determine the cause for the dis-
turbance, have your vehi cle towed to the near-
est Porsche or tire dealer to have your vehicle
or tire(s) inspected.
f Continuing to operate the vehicle without cor-
rection could result in a loss of control and serious personal injury.
ExampleUniform Tire Quality GradingQuality grades can be fo und where applicable on
the tire sidewall between tread shoulder and max-
imum section width.
All passenger car tires must conform to Federal
Safety Requirements in a ddition to these grades.
Tr e a d w e a r
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specific govern-
ment test course.
For example, a tire graded 150 would wear one

– 295 - Indication of tire width in mm
– 30 - Indication of tire height to tire width ratio
in percent –
ZR - code letter for radial tires for speeds
above 150 mph / 240 km/h
There are currently no standards concerning
tire strength at speeds above 150 mph
(240 km/h).
– R - Belt type code letter for radial
– 19 - Indication of rim diameter in inches
– 100 - Load capacity coefficient
– Y - Speed code letter

ing
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 manufacturer’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
0208, the tire was produced in the 2nd week
of 2008.
C Tire ply composition and material
The number of layers in the tread and sidewalls
and their material composition.
D Maximum permissible inflation pressure

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.
FRadial
The identification indicates if the tire has radial
structure.
G Term of tubeless or tube tire
Identification for tubeless tires.Speed code letterThe speed code letter indicates the maximum per-
missible speed for the tire.
This code letter is shown on the tire sidewall.Tip on driving
Tires with a maximum speed rating that is lower
than the specified maximum vehicle speed may be
mounted only if they bear an M+S identification on
the tire sidewall.
f
Please note that in addition to the winter tires,
all-season and all-terrain tires are also subject
to speed limits and bear this identification.
