different tire speeds. For this reaÂson, 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 othÂ
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 difÂ
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.
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to veÂ
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

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. .,.

Wheels
-Have an authorized Audi dealer or authorized repair facility
check the wheel alignment if
there is unusual wear .
-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
The original tires on your vehicle
have 1/16 inch (1.6 mm) high
"wear indicators"¢
fig. 194 runÂ
ning across the tread. Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear inÂ
dicators.
The tires have reached the miniÂ
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones ¢Ai..
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly . To rotate wheels, inÂ
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 unidirectional tires, make
sure the tires are installed accordÂ
ing to the running direction indiÂ
cated on the tire sidewall
¢page 258.
Hidden damage
Damage to tires and rims can ofÂ
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 outÂ
side, drive slowly and carefully to
the nearest authorized Audi dealÂ
er or authorized repair facility to
have the vehicle inspected.
A WARNING ~
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a negaÂ
tive effect on handling, on the

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 alÂ
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 pasÂ
sengers also depends on making
sure that load limits are not exÂ
ceeded. Vehicle load includes evÂ
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehiÂ
cle's
Gross Vehicle Weight RatÂ
ing
("GVWR") .
The "GVWR" includes the weight of the basic vehicle, all factory inÂ
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load . The maxiÂ
mum load includes the number of
passengers that the vehicle is inÂ
tended to carry ("seating capaciÂ
ty") with an assumed weight of 1 SO lbs. (68 kg) for each passenÂ
ger at a designated seating posiÂ
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer hitch and the tongue weight of
the loaded trailer must be includÂ
ed as part of the vehicle load.
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-
244
cle Weight Rating means that the
total weight of whatever is being carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pasÂ
sengers in the vehicle or passenÂ
gers who are heavier than the
standard weights assumed 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 compliÂ
ance sticker label located on the
driver's side B-pillar
¢ page 241,
fig. 195.
&_ WARNING ~
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious perÂ
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.
Page 247 of 294

-Tires on a vehicle that has
been overloaded can fail sudÂ
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 trailÂ
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 calcuÂ
late the total weight of the pasÂ
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overloadÂ
ed.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU Â
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS "on your vehicle's placard
(tire inflation pressure label)
¢ page 241, fig. 195.
Wheels
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 241, fig . 195 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For exÂ
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.
That weight may not safely ex ceed the available cargo and
luggage load capacity calculatÂ
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your veÂ
hicle. Consult this manual to
determine how this reduces ..,

- Only use wheel bolts that fit the rim.
-Always have damaged rims repaired by an authorized Aud i dealer or authorized repair
facility . Never repair or d isassemble rims

an accident .
Winter tires
Winte r ti re s s ignificantly improve the veh icle's
h a ndling when d riving in w inte r condi tions. BeÂ
c a use of the ir cons tru ction (width, compound,
tread pattern), summe r tires provide less tracÂ
tion o n ice and snow.

.,. Use win ter tires on a ll four wheels .
.. On ly use winter tires that are approved for yo ur
veh icle.
.,. Please note that the maximum permitted
speed may be lower with winter tires¢&_ .
Your authorized Audi dealer or authorized re Â
pa ir fac ility can inform you about the maxim um
permitted speed for your t ires .
.,. Check t he tire p ressure afte r insta lling wheels
~ page 241.
The effectiveness of wi nter tires is reduced g reatÂ
l y when the tread is wo rn down to a depth of
0.157 inch ( 4 mm). The chara cte ris tic s of winter
ti res a lso decrease g rea tly as the t ire ages, reÂ
gard less o f the remaining t read.
_&. WARNING
- Never drive faster than the maximum pe rÂ
m itted speed for your tires . This could cause
the t ires to heat up too much. This increases
the risk of an accident because it can cause
the t ire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose t ract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropr iate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fuel
consumpt ion.
(i_) Tips
You can also use all season tires instead of
winter tires . Please note that in some counÂ
tries where wint er tires are required, o nly
winter tires w it h t he
& symbol may be perÂ
mi tted.
Snow chains
Snow chains improve trac tion in the snow.
.,. On ly install snow chai ns on the fron t wheels .
T his applies a lso to vehicles with a ll wheel
dr ive*.

Page 249 of 294

~ Check and correc t the seating of the snow
chains if necessary after driving a few feet. FolÂ
l ow the instructions from the manufacturer .
~ Note the maximum permitted speed when drivÂ
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Snow chains not only improve the
driving in winÂ
ter road cond itions, but also the
braking.
Use of snow chains is on ly permitted with certain
rim/tire combinations due to tec hnical reasons .
Check with an authorized Audi dealer or author ized repair facility to see if you may use snow
cha ins.
You must remove the chains when driving on roads that are
free of snow. When roads are free
of snow, snow chains can impair handling and
damage the t ires, and the chains w ill quickly be
destroyed .
A WARNING
Using incorrect snow chains o r installing snow
chains incorrect ly can result in loss of vehicle
c ont rol, w hic h in cr eases the risk of a n acci Â
de nt.
- Snow cha ins can damage the rims/wheel
covers* if the cha ins come into d irect conÂ
tact wi th them . Remove the whee l cove rs*
first. Use coated snow cha ins.
- Usi ng snow chai ns tha t add more than 0.4
i nch (10.5 mm) of he igh t ca n severely damÂ
age the wheel ho usings and othe r vehicle
components .
- Do no t install and use s now chains if there is
a mal funct ion in the adaptive air suspen Â
sion*, because the vehicle height wi ll be
very low. If you d rive with snow chains anyÂ
way, the wheel ho usings and othe r vehicle
components can be severely damaged.
Low aspect ratio tires
Your Aud i is factory -equipped with low aspect raÂ
tio tires . These t ires have been tho rough ly tested
and been se lected specifically for yo ur model fo r
Wheel s
their superb performance, road fee l and handling
u nder a variety of driving conditions . Ask your auÂ
thorized Audi dea le r fo r more detai ls.
T he low aspect rat io o f th ese tires is indicated by
a n umeral of
55 or le ss in the tire's size des ignaÂ
tion . The numera l represents the ratio of the
t ir e's s idewall height in relation to its tread w idth
expressed in percentage. Conventiona l tires have
a he ight/width ratio of 60 or more.
The performance of low-aspect- ratio tires is parÂ
ticularly sen sitive to imprope r inflat ion presÂ
s ure. It is the refore important that low aspect
rat io tires are inflated to the speci fied pre ssure
and that the inflation pressure i s regularly
checked and m aintain ed. Tir e pr essures should
be checked at least once a month and always
b efor e a long trip
~ page 241.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged more eas iÂ
ly by impact w ith po tholes, curbs, gullies or
ridges on the road, particularly if the tire is un Â
deri nflated.
In orde r to m in imize the occurrence of impact
damage to t he tires of yo ur vehicle , we recom Â
me nd that you observe the following pre ca uÂ
t ions:
- Always ma intain recommended inflat ion presÂ
sures. Check yo ur tir e pressure every 2,000
m iles (3 ,00 0 k m) and add air if necessary.
- Dr ive ca refully on roads w it h potholes, deep
gullies o r ridges. T he impact from dr iving
t hrough or over such obstacles can damage
your tires. Impac t wi th a curb may a lso ca use
damage to your tires.
- Afte r any impac t, immed iate ly inspect yo ur
t ires or have them inspected by the nearest au Â
thorized A udi dealer. Rep lace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ich could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged, replace the tire as soon as pos -
sible . .,.

Reduced performance in wint er/ cold season
condit ion s
All tires are designed for certain purposes. The low aspect ratio, ultra high pe rformance tires
or iginally insta lled on yo ur vehicle are intended
for maximum d ry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weathe r cond itions .
If you drive under those
circumstances, you should equ ip your ve hicle
