The speed rating letter code (c::> page 228) is
on the side wall of the tire
c::> page 236.
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
w inte r tires . This will cause damage to the
t ires leading to an ac ciden t and se rious
pe rsonal in jury to you and yo ur passen­
ge rs .
A WARNING
Dr iv ing faster than the maximum speed
for which the winter tires on your vehicle
were designed can ca use tire fai lure in­
cl uding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
rep laced immed iate ly.
- Winter tires have maximum speed rat ing
that may be lower tha n your ve hicle's
maximum speed .
- Never drive faster than the speed for
w hich the winter or other tires installed
on your veh icle are rated .
A WARNING
Always adjust your d rivi ng to the road and
traffic conditions. Neve r let the good ac­
c eleration of the w inte r ti res an d all-whee l
drive temp t you in to taking extra r is k s . A l­
ways remember :
- When bra king, an a ll-wheel d rive vehicle
hand les in the s ame way as a front drive
vehicle.
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
@l For the sake of the environment
Use summe r tires w hen weathe r cond i­
tions permit. They are quieter, do not we ar

Snow chains
Snow cha ins may be fitted only to the front
whee ls , a nd o nly to certa in ti re si zes. As k your
autho rized Aud i dea ler on whi ch tire sizes
snow chains can be used.
If you a re go ing to use snow cha ins, then you
mus t install t hem on the front whee ls a t
least.
T he snow chains must have low-p rofi le links
and must not be th ic ker than 0.53 inch
(13,S mm) , in cl ud ing t he lo ck.
Remove whee l cen ter covers and t rim discs
before putt ing snow cha ins on your veh icle
c::> (]) . For safety reasons cover caps must t hen
be fi tte d over the wheel bol ts. These are av ail­
able from autho rized Aud i dealers .
A WARNING ,..__
Using the wrong snow chains for your vehi ­
cle o r insta lling them incorrect ly can in ­
crease the risk of loss of contro l leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions prov ided by the snow chai n
manufacturer .
- When driving wit h snow cha ins neve r
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow c hains before driving o n
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 whee l rim, ca n scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
t he pos ition of the snow chains afte r
dr iv ing a few yards and co rrect if neces­
sary. Follow the inst ru ct io ns from the
snow chain m anufacturer w hen do ing so. ..,.

24 2 T ire s and wheel s
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory installed rims . If different rims are fit­
ted, the correct wheel bolts with the right
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 270.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
c ont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­ er ly t igh tened .
- 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 th e 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 wheel bolts diago­
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque w rench -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
ra tio 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 d riving 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 n umera l represents the ratio
of the tire's sidewall 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
pressure. It is therefore important that low
a spect ratio tires are inflat ed to the specified
pre ssure and that the inflation pressure i s
regularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and always bef ore a long trip
r=> page 231, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amage d more
easily by impact w ith potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.

In o rder to minimize the occu rrence 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
t h rough 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 t ire fail ure.
If yo u be lieve that a
tire may have been damaged , replace the
tire as soon as possible.
- These tires may wear more qui ck 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 choices.
Reduced p erformance in winter /cold
sea son condit ion s
All tires are designed for certain purposes .
The low aspect ratio, ultra hig h performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
f ormance 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, which offer better traction under
those cond it io ns . 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
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 manufac turer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire i n­
flat io n pressu re labe l, you shou ld dete rm ine
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 mon ito ring
system ( TPMS) that illum inates a low ti re
pressure te lltale when one or more o f your
t ires is significant ly under -inflated . Acco rding ­
l y, when the low tire pressure te lltale i llumi­
nates, you should 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 tire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al­
so reduces fuel eff ic iency and tire tread life,
and may affe ct the vehicle's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
fo r proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under -inflation has not
rea ched the leve l to tr igger illuminat ion of the
TPMS low tire p ressure tellta le .
You r vehicle has also been equipped with a
T PMS ma lfunction indicator to ind icate when
the sys tem is not operating properly . T he
TPMS ma lfunction indicator is combined with
the low tire pressure te lltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximate ly one min ute and then
rema in continuously illum inated . Th is se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunct io n exists.
When the malfunction indicator is illum inat-
ed, the system may not be ab le to detect or

signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
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.
If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 161 Ins trumen t cluste r: ind icato r light w it h m es­
s age
Using the ABS sensors, the tire pressure moni­
toring system compa res the tire tread circum­
ference and vibration characteristics of the in­
dividual tires .
If the pressure changes in one
or more tires, th is is indicated in the instru­
ment cluster display with an indicator light
IE and a message ¢ fig. 161 . If only one t ire
is affected, the location of that t ire will be in­
d icated. The message turns off after a few mi­
nutes. You can disp lay the message again
¢ page 28.
The tire pressures must be stored in the menu
d isplay aga in each time the pressures change
(switching between part ia l and full load pres­
sure) or after chang ing or replac ing a tire on
your ve hicle ¢
page 245. The tire pressure
monitoring system on ly monitors the ti re
press ure you have stored . You can find the rec­
ommended tire pressures for your vehicle on the
labe l on the driver's doo r pillar

significantly under-i nflated tire causes
the t ire to overheat and can lead to ti re
fa ilur e. Unde r-inflation also is li kely to

impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be de layed.
