New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­
ment parts.
.,.New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,.Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
224
.,.Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires may perform differently even if
they are the same size ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur­
chase ¢&, .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, 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 damaged by .,.

different tire speeds. For this rea­son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
&_ 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.
Wheels
-Only use tires that are more
than 6 years old when abso­ lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 189 Tire profile : treadwear indica­
tor
Tire wear
Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear .
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear. ..
225

Wheels
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are
1/16 inch (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion¢
fig . 189 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the treadwear
indicators . Replace the tires with
new ones ¢A.
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice
versa. This will allow the tires to

have approximately the same
length of service life.
For unidirect ional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 244.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage . If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.
8_ WARNING
Tread that has worn too low or different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving
through water, when driving ,..

....
through curves and when brak­ing, which increases the risk of
an accident.

the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.

A WARNING
Please note the important safe­
ty precautions regarding tire pressure ¢
page 22 7 and load
limits ¢
page 229 .
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
a nd any tire c an carry . A vehicle
that is overloaded will not handle
well and i s more difficult to stop .
O verloading can not only lead to ..
229

increase the risk of the loss of
vehicle control.
- The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas ­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed.
Wheels
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
~ page 227, fig. 190.
2.
Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from
" XXX " kilograms or "XXX "
pounds shown on the sticker
¢page 227, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the
" XXX " amount
equals
1400 lbs. and there will
be five
150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs.
(1400-750 (5 X 150) = 650
lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.

Wheel bolts and rims
Wheel bolts
W heel bol ts must be clean and loosen/t ighten
eas ily.
Rims
R ims with a bolted rim r ing * or w it h bolted whee l
covers * consist of mu ltiple pieces . These compo ­
nents were bolted together using specia l bolts
a nd a special procedu re. You must not repair o r
d isassemble th em¢ ,&..
_& WARNING
Whee l bolts tha t are t ightened o r repa ire d in­
correctly can become loose and resul t in loss
of vehicle control, which increases the risk of
an acc ident. For the correct t ightening specif i­
cat ion, refer to¢
page 241, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the whee l hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
232
- Always have damaged rims repaired by an
author ized Audi dealer or authorized Audi
Serv ice Facility. Neve r repa ir or disassemb le
r ims you rself, because this increases the risk
of an accident.
Winter tires
Win ter tires significantly improve the vehicle's
handling when dr iv ing in winter conditions. Be­
ca use of their const ru ct ion (w idth, compou nd,
t read pat te rn), summer t ires provide less t rac­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. Onl y use winter tires that a re approved fo r yo ur
veh icle.
.,. Please note that t he maximum permit ted
speed may be lower with winter tires¢.&_ . An
authorized A udi dealer or authorized Audi
Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after insta lling wheels
¢ page 227.
The effectiveness of winter tires is reduced great­
l y when the tread is worn down to a depth of
0 .157 in (4 mm). The characteristics of winter
tires also decrease g reatly as the tire ages, re­
gard less of the rema ining t read .
_& WARNING
-
-Never d rive fas ter than the max imum pe r­
m itted speed for your tires. This could c ause
the t ires to hea t up too m uch. T his increases
the risk of an accident because it can cause the t ire to burst.
- Always ada pt your driving to the road and
traffic conditions. Drive carefu lly and reduce
your speed on icy or slippery roads. Even
winter t ires can lose tract ion on black ice.
@ For the sake of the environment
Reinsta ll summer tires a t the appropriate
time, beca use they provide better handling
when roads are free o f snow and ice. Summer
tires cause less road no ise, tire wear and fuel
consumpt ion.
