> Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
differently even if they are the
same size > A.
>If you would like to equip your
vehicle with a tire and rim com-
bination that is different from
what was installed at the facto-
ry, consult with an authorized
Audi dealer or authorized Audi
Service Facility before making a
purchase > A.
Because the spare tire® is differ-
ent from the regular tires instal-
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re-
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: All four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam-
aged by different wheel speeds.
For this reason, in case of emer-
gency, only use a spare tire* that
is the same circumference as the
regular tires.


AN WARNING
—Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
—For technical reasons, it is not
possible to use tires from oth-
er vehicles. In some cases, you
cannot even use tires from the
same vehicle model.
—Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif-
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
—Only use tires that are more
than six years old when abso-
lutely necessary and drive
carefully when doing so.

Wheels

Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

ZA WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 352, After changing a
wheel.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.

> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 319. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 330.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
(@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
@) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the 44 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
Use fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in height, includ-
ing the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.
() Note
Snow chains can damage the rims and wheel
covers* if the chains come into direct contact

Emergency assistance

Removing the wheel
>» Use the hexagonal socket in the screwdriver
handle to completely remove the topmost
wheel bolt and set it aside on a clean surface
> fig. 273.
> Screw the threaded end of the alignment pin
from the tool kit hand-tight into the empty bolt
hole > fig. 274.
> Then remove the other wheel bolts as described
above.
> Take off the wheel leaving the alignment pin in
the bolt hole >@).
Putting on the compact spare wheel
> Lift the spare wheel and carefully slide it over
the alignment pin to guide it in place >@.
> Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel bolts
slightly.
> Remove the alignment pin and insert and tight-
en the remaining wheel bolt slightly like the
rest.
> Turn the jack handle counter-clockwise to lower
the vehicle until the jack* is fully released.
> Use the wheel bolt wrench to tighten all wheel
bolts firmly > page 353. Tighten them cross-
wise, from one bolt to the (approximately) op-
posite one, to keep the wheel centered.
@) Note
When removing or installing the wheel, the
rim
could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
G) Tips
Never use the hexagonal socket in the handle
of the screwdriver to loosen or tighten the
wheel bolts.
— Pull the reversible blade from the screwdriv:
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
— When mounting tires with unidirectional
tread design make sure the tread pattern is
pointed the right way > page 356.
— The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
356
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be-
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire with a tread pattern in-
tended for use in a specific direction, please note
the following:
— The direction of rotation is marked by an arrow
on the side of the tire.
— If the spare tire has to be installed in the incor-
rect direction, use the spare tire only tempora-
rily since the tire will not be able to achieve its
optimum performance characteristics with re-
gard to aquaplaning, noise and wear.
— We recommend that you pay particular atten-
tion to this fact during wet weather and that
you
adjust your speed to match road condi-
tions.
— Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec-
tional tire.
Notes on wheel changing
Please read the information > page 326 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After you change a tire:
— Check the tire pressure on the spare immedi-
ately after installation.
— Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos-
sible by your authorized Audi dealer ora
qualified service station.
— With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs (120 Nm).
