8,_ 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
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve­ hicle damage or accidents.
-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

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.

..

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 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion¢
fig . 197 . 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 tread wear
indicators . Replace the tires with
new ones ¢A.
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires,
install the t ires 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 unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 286.
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

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden

tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle 's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids ..
267

Wheels
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle is limited.
The more passengers in the vehi­ cle or passengers who are heavier
than the standard weights as­
sumed mean that less weight can
be carried as luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
c::> page 265,
fig. 198.
A WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
268
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and
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 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 . ..

Steps for Determining Correct Load Limit
1 . Locate the stat em ent "THE
COMBINED WEIGHT OF OCCU­ PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR X XX
LBS "on your vehi cle 's pla card
(tire inflation pr essure l abel)
¢ pag e 265 , fig. 198.
2 . Determine the combined
weight of the dri ver and pa s­
sengers that will be riding in
your vehicle.
3. Subtract the comb ined weight
of the driver and passengers
from
" XXX " kilograms or "XXX "
pounds shown on the sticker
¢ page 265, fig. 198 .
4. The resulting figure equals the
available amount of cargo and
luggage load ca pac ity. For ex­
ample, if the
"X XX" amount
equals 1400 lbs and there w ill
be five 150 lbs passengers in
your vehicle , the amount of
available cargo and luggage
load capacity is 650 lb s
(1400- 750 (5
X 150) = 650 lbs)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.

Winter tires
W inter tire s significan tly improve the vehicle 's
handling when driving in w inter condi tions. Be­
cause of the ir construction (width, compound,
tread pattern) , summe r tires p rovide less trac­
tion o n ice and snow.
.. Use w inter t ires o n all four wheels .
.. Only use w inter t ires that are approved for your
vehicle .
.. Please note that the maximum permitted
speed may be lower with winter tires
¢ & -An
a utho riz ed Aud i dea le r o r authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed fo r you r tires.
.. Check the tire pr essu re after installing whee ls
¢ page 265.
The effectiveness of winter tires is reduced great ­
ly whe n the tread is wor n down to a depth of
0 .157 in (4 mm). The character istics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never dr ive faste r than the maxim um per ­
mitted speed for your t ires . This cou ld cause
the tires to heat up too much. This increases
t h e risk of an a cciden t be ca use i t can c ause
t h e tire to burst.
- Always adapt yo ur driv ing to t he r oad and
t ra ffic conditions. Drive ca refully and red uce
yo ur sp eed on icy or slippery roads. Even
winte r tires can lose traction on black ice .
@ For the sake of the environment
Reinstall su mme r tir es at the approp ria te
t ime, because they provide bet ter ha ndling
when ro ads are free of snow a nd ice. S ummer
t ires cause less road noise, ti re wea r and fuel
consumption.

(D Tips
You can also use a ll season tires instea d of
winter tires . Please note that in some coun­
tries where winter tires are required, on ly
winter tires w it h the
& symbol may be per­
mitted.
' Snow chains
S now cha ins not on ly improve the driv ing in win­
te r road cond it io ns, but a lso the b raking .
.. On ly install snow chai ns on the front wheels .
T his applies also to vehicles with all wheel
dr ive*.
.. Check and co rrect t he seating of the snow
chains after driving a few feet, if nece ssary. Fol­
low t he inst ructions from the m anufac turer.
.. Note the max imum speed of 3 0 mph (50 km/
h). Note the local regulations.
U se of snow c hains is only permitte d wit h cert ain
rim/ tire comb inat ions due to technical reasons.
Check with a n authorized Audi dealer or author ­
i zed Audi Service Facility to see if you may use
snow chains.
You m ust remove the snow chains on roads wi th­
out snow . Otherwise, you co uld impair driving
ability and damage the t ires .
A WARNING
Using incor rect snow chains or installing snow
cha ins incor rectly can result in loss of vehicle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel
covers* if the c hains come into direct con­
tact with them. Remove the w heel covers *
first . Use coated snow cha ins .
- Us ing snow c hains that add more tha n 0.53
in (13,5 mm) of height can seve rely damage
the whee l housings and o ther vehicle com­
ponents .
