2004 PORSCHE CAYENNE wheel

Minor Repairs Note
Under no circumstances should tires older than
6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT”
code number. If, for example, the last three num-
bers read 1208, then the tire was produced in the
12th week of 2008.
Snow tiresThe installation of Porsche approved winter tires is
recommended.
Use Porsche approved winter tires for grip on
snow and ice. For optimum performance, stud-
ding can be considered.
Check with your local Motor Vehicle Bureau for
possible restrictions.
Danger!
Risk of loss of control and damage to the
vehicle as well as serious personal injury or
death.
The standard tires profile and rubber mixture
are optimized for wet and dry driving condi-
tions, and may not prove favorable for snow
conditions.
fInstall winter tires before driving in such condi-tions.Before mounting winter tires, consult with your
Porsche dealer. He has the technical information
necessary to advise you on wheel and tire compa-
tibility.
fSnow tires should have the same load capacity
as original equipment tires and should be
mounted on all four wheels.
Winter tires with studs should be run at mode-
rate speeds when new in order to give the
studs time to settle.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases increases risk of a tire failure and
resulting loss of control. Furthermore, low
tire pressure increases rate of wear of the
affected tires and cause damage.
Tires with badly worn treads and studs are
very dangerous and could cause accidents
resulting in serious personal injuries or
death.
fMake sure they are replaced immediately.
fDo not exceed the winter tire speed rating.
Snow tires do not have the same degree of trac-
tion on dry, wet or snowfree roads as normal tires.
Furthermore, snow tires wear rapidly under these
conditions.Maintenance Note
We recommend fitting winter tires on the vehicle at
temperatures below 45 °F (7 °C) since the driving
performance of summer tires is reduced at low
temperatures. Summer tires may be permanently
damaged at extremely low temperatures.
Winter tires do not fulfill their purpose if the tread
depth is less than 5/32 in. (4 mm).
Comply with all state and local laws gover-
ning snow tire and tread depth requirements.
Danger!
Risk of accident and serious personal injury
or death due to excessive speed.
fAlways check the maximum speed rating on
the tire sidewall on any tire on the vehicle.
fNever exceed the maximum speed rating of the tires.
Wheel change
fWhen wheels are removed, mark the direction
of rotation and position of each wheel.
Example: FR (front right), FL, RR and RL.
fAlways fit the wheels in accordance with the
markings.

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.

Speed code letterThe speed code letter indicates the maximum per-
missible speed for the tire.
This code letter is shown on the tire sidewall.
T = up to 118 mph (190 km/h)
H = up to 131 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
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.
fPlease note that in addition to the winter tires,
all-season and all-terrain tires are also subject
to speed limits and bear this identification.

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
removed before mounting 18 inch tires or
collapsible spare wheel.
f17 mm spacers are always to be removed
before 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
before 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

Tightening torque of the wheel bolts and wheel
nuts 118 ftlb. (160 Nm).
Security wheel boltsThe adapter (wrench socket) for the security
wheel bolts is located in the tool box.
To loosen or tighten the wheel bolt with anti-theft
protection, the adapter must be used between the
wheel bolt and the wheel bolt wrench.
fWhen positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
Note on operation
fOn vehicles with 17 mm spacers on the rear
axle, the wheels are secured with steel nuts.
There is no anti-theft protection for the wheel
nuts.
fIf the wheels have to be removed at the work-
shop, please do not forget to hand over the
socket for the security wheel bolts along with
the car key.
Changing Wheels
Warning!
Failure to follow these instructions may result
in serious personal injury or death to you or
to bystanders.
Before changing the wheel
fIf you have a flat tire, move a safe distance off
the road. Turn the emergency flasher on and
use other warning devices to alert other
motorists.
fDo not park your vehicle where it may contact
dry grass, brush or other flammable materials.
The hot parts of the exhaust system could set
such materials on fire, thereby causing both
property damage and severe or fatal physical
injury.
fPassengers must not be in the vehicle when it
is jacked up.
fBefore you change a wheel, be sure the ground
is level and firm. If necessary, use a board
under the jack to ensure that the jack does not
sink into the ground.
fSet the parking brake and block the wheels
opposite the flat tire on the other side of the
vehicle.While operating the jack
fThe jack is only to be used for changing a
wheel. Do not use it as a support to work under
the car.
fThe car must be jacked up only at the illustra-
ted jacking points.Lifting at any other place
may damage the vehicle or may result in per-
sonal injury. Never jack the car up by the body
or the bumpers.
fFor safety reasons do not use tire inflating bot-
tles. Do not use commercially available sealant
bottles. Use only the tire inflating bottle
located in the luggage compartment.

lane as possible.
The car must be parked on a firm and flat
surface offering adequate grip.
2. Switch on the emergency flashers.
3. Fully apply the parking brake.
4. Shift into 1st gear or move the Tiptronic
selector lever to position P.
5. Straighten the front wheels.
6. Withdraw the ignition key to lock the steering
and prevent the engine from being started.
7. Have any passengers leave the vehicle.
8. Set up a warning triangle at a suitable
distance.
