New tires or wheels
Audi recommends having all work on tires or wheels performed by
an authorized Audi dea ler or au ­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equ ipped with
the required tools and replace­
ment parts .
.,,. New tires do not yet have the
opt imum adhesion properties .
Drive carefully and at moderate
speeds for the first 350 m iles
(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 .
Tires a nd whe els
.,,. 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 different ly even if
they are the same size
c:::> ,& .
.,,. 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
c:::> ..1,. .
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 d riv e 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

"' N
~
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty 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 .
Treadwe ar indic ato r
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 even ly around the tire per­
pend icular to the running direc­
tion
¢ fig. 169. The letters "TW I"
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¢ &.
Whe el rot ation
Rotating the wheels regularly is
recommended to ensure the tires
;;; l) Obey any applicable regu lation s in your ~
~ country . ....
Tires and wheels
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice ver­
sa. This will allow the tires to
have approximately the same
length of service life.
F or unidirectional tires, make sure
the tires are installed according to
the running direction indicated on
the tire sidewall¢
page 245.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hid ­
den. Unusual vibrations in the ve­
hicle or pulling to one side may
indicate that there is tire damage .
Reduce your speed immed iately .
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.
A WA RNING
-
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consis t of mul tiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble them
Q ,& .
Tires and wheels
A 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, refer to~
page 242, A~er 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
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
Q _& . An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
Qpage 224.
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.
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst.

Tires and wheel s
-Always adapt your driving to the road and
traff ic conditions. Dr ive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose tract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow a nd ice. Summer
tires cause less road noise, tire wear and fuel
consumptio n.
(D Tips
You can also use all season tires instead of
w inte r tires. Please note that in some coun­
t ries w here winter tires are requ ired, on ly win­
t er tire s wi th the .& symbol may be pe rm it­
t ed.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
Th is applies also to veh icles with all wheel
drive* .
.,. Ch eck and correct the seating of th e snow
c h ains if necessa ry afte r dri ving a few feet. Fo l­
l ow the ins tructions from the manuf acturer.
.,. Note t he max imum permit ted speed w hen driv ­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
Snow chains not only improve the
driving in win ­
ter road conditions, but a lso t he
braking .
Use of s now chai ns is o nly pe rm itted with certa in
r im/t ire comb ina tion s due to techn ica l reason s.
Chec k w ith an au thori zed A udi d ealer or au tho r­
ized A udi Service Facility to see if yo u may use
snow cha ins.
Use
fine -mesh snow chain s. They mus t not add
mo re th an 0 .5 3 inch ( 13.S mm) in height, in clu d­
ing the chain lock.
You must remove the chai ns when dr iv ing on
roads tha t are
free of snow. W hen r oads are free
of snow, snow chains can imp air handling an d

'
damage the tires, and the chains wi ll quick ly be
dest royed.
A WARNING
Using incorrect snow chains o r insta lling snow
cha ins incor rectly can res ult in loss of veh icle
c o ntrol, which increases the risk of an acc i­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the c hains come into direct c on­
tact with them. Remove the wheel covers*
first . Use coa ted snow cha ins.
Low aspect ratio tires
Your A udi is fac to ry-eq uipped w ith low aspect ra­
t io t ires. These t ires have been thoroug hly tes ted
a nd been sele cted specifi ca lly f or your mode l for
the ir su perb pe rformance, r oad fee l and h andlin g
u nder a var iety of dr iv ing con ditions. As k your au ­
t h orized Aud i dea le r fo r more details .
The low aspe ct ratio of these tires is ind icated by
a n umer al of
55 or less in the t ire's s ize design a­
tion . The nume ral represents the ratio of the
ti re's si dewall height in relatio n to its tread width
expressed i n pe rcentage. Conventional tires have
a height/width rat io o f 60 o r more .
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to imprope r inflation pres­
sure. It is therefore important that low aspect ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should be checked at least once a month and always
b efor e a long trip
Q page 224 .
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged mo re eas i­
l y by impact w ith potho les, c urbs , g ull ies o r
r idges on t he road, pa rti cularly if th e tire is un ­
der i nflated.
