The speed rating letter code (c::> page 233) is
on the side wall of the tire
c::> page 242 .
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires . This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in cluding a blowout and sudden deflation,
loss of control, crashes and serious per
sonal injuries . Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al
ways remember :
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@l For the sake of the environment
Use summer tires when weather condi
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.

Tires and wheels
Snow chains
Snow chains may be fitted only to the front
wheels , and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch
(10,S mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (]) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail
able from authorized Audi dealers.
A WARNING ,..__
Using the wrong snow chains for your vehi
cle or installing them incorrectly can in
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in
structions provided by the snow chain manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow chain manufacturer when doing so. ..,.

248 Tire s and whee ls
Where snow chains are mandatory oncer
tain roads, this normally also applies to ve
hicles with a ll-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r=> page 275.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop
er ly t ightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bo lts is too low, they
can loosen and come out w hen the veh i
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque whee l bolts diago
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w it h low aspect
ratio tires. These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage. Conven
t iona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pre ssure. It is therefore important that low
a spect ratio tires ar e inflat ed to the specified
pre ssure and that the inflation pressure i s
r e gularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and alw ays bef ore a long trip
r=> page 237, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amaged more
easily by impact with potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.
Page 251 of 294

In o rder to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom mend that you observe the following precau
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ire as soon as poss ible .
- In spect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al
ways easy to see. Damage can lead to loss of
air and unde rinflation, wh ic h could eventu
ally cause ti re fail ure.
If yo u be lieve that a
ti re may have been damaged , replace the
tire as soon as possible.
- These tires may wear more quick ly than oth
ers.
- Please a lso remembe r that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other c hoices.
Reduced p erformance in winter /cold
s ea son condit ion s
All ti res are designed for certain purposes .
The low aspect ratio, ultra hig h performance
tires originally installed on your veh icle are in
tended for max imum dry and wet road per
formance and handling . They are not suitable
for cold, snowy or icy weather cond it ions . If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, whi ch offe r better traction under
those cond it ions . We suggest you use the rec
ommended snow or all -season tires specified
for your ve hicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
App lies to vehicles : wi th tire p ress ure mo nito rin g system
Each tire, incl uding the spare (if provided),
shou ld be checked monthly when co ld and in
flated to the inflation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s iz e indicated on the vehicle placard or tire in
flat io n pressu re labe l, you shou ld dete rmine
the p roper t ire inflation p ress ure fo r those
t i r es).
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low ti re
pressure te lltale whe n one or more o f your
ti res is significant ly under -inflated . According
ly, when the low tire pressure te lltale i llumi
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing abil ity.
Please note that the TPMS is not a subst itute
fo r proper tire ma intenanc e, and it is the d riv
er's respo nsibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low ti re p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate w hen
the sys tem is not operating prope rly . T he
T PMS ma lfunction indicator is combined w ith
the low tire pressure te lltale. When the sys
tem detects a malfunction, the telltale wi ll
flash for approximate ly one min ute and then
rema in con tinuously i llum inated . T hi s se
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists . ..,.

250 Tires and wheels
When the malfunction indicator is illuminat
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea
sons, including the installation of replace ment or alternate tires or wheels on the vehi
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunction
telltale after replacing one or more t ires or
wheels on your veh icle to ensure that the re
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
