& WARNING
The traction grade ass igned to this t ire i s based on straight -ahead
braking traction tests, and does not include acceleration,
c ornering , hydroplaning or peak tra ction chara cteristic s.
& WARNING
The temperature grade for this t ire is established for a tire that is
properly inflated and not overloaded. Excessive speed , underinfla ­
tion , or ex ces sive loading , either separately or in combination , can
c ause heat buildup and possible tire failure . •
Winter tires
Wi nter tires c an im prove vehicle handli ng on snow and
ic e. At t emperatures below 4 5 °F (7 ° C) we re commend
cha ngi ng to winte r tires.
In some heavy snow areas, local governments may require true
winter o r "snow" tire s, those with ve ry deeply cut tread. These tires
s h ou ld on ly be used in pairs and be i nstalled on all four wheels .
M ake sure you purchase snow tires that are the same si ze and
co nstruction type as t he o the r tires on your veh icle .
I f your vehicle is equipped with all -wheel drive *, this will improve
t raction d uring win te r dr iving, eve n with the s ta n dard t ires .
However, we strongly recommend that you always equip a ll four
w hee ls on you r vehic le wi th cor rec tly fi tted w inter tire s or all-season
t ir es, when w inter road co nditions ar e expec ted . T his also improves
the vehicle 's br aking perfo rmance and reduces stopping distance s.
Summer tires p rov ide less gr ip on ice a nd sno w.
Winter tires (snow tires) must a lways be fitted on all four whee ls .
Ask you r author ized Aud i deale r o r qualified wo rksho p fo r pe rmitted
winter tire sizes . Use only rad ial wint er tires. Winter tires
lose their effec tiveness when the tread is worn down to
a depth of 0 .1 57 inch (4 mm).
Only drive with w inter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
t emperature is above 45 °F (7 °C).
I f you have a flat tire, see notes on spare whee l
~ page 329.
Please always remember that winter tires may have a lower speed
rating than the tires original ly installed on your vehicle at the time
it was man ufact ured. Please see~
page 330, "Speed rating (lette r
code)" for a l ist ing o f th e speed rati ng lette r codes a nd the
maximum speed at which the tires can be driven.
The s peed rati ng letter code(~

~ page 329 .
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle' s maximum 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 acc ident and serious personal injury to you and your
passengers .
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , loss of control , crashes and serious
personal injuries . Have worn or damaged tires replaced immedi ­
ately.
• Winter tires have max imum 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 . ...

& WARNING
Always adjust your driving to the road and t raffic condit ions .
Never let the good a cceleration of the winter tires and all -wheel
dri ve tempt you into tak ing extra ri sk s. Always remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and redu ce your speed on icy and sli ppery roads ,
even winter tires cannot help unde r bla ck ice conditions.
c£> For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, d o no t wear as quick ly a nd re duce fuel consump tio n.•
Snow chains
Snow cha ins may be fitte d o nly to the fron t whee ls, and o nly to
certain tire sizes . Ask your authorized Audi dealer on which tire
s iz es snow c hains can be used.
If you are going to use snow chains, then you must install them on
the front wheels at least.
The snow cha ins must have low -profile l inks and must not be thicker
than 0 .53 inch ( 13.5 mm), including the lock.
Remove wheel center c overs and trim discs before putt ing snow
chains on your vehicle~
0 . For safety reasons cover caps must
then be fitted ove r the wheel bo lts . These are avai lable from autho­
r ized Aud i dealers.
& WARNING
Using the wrong sno w chains for your vehi cle or installing them
incorre ctly can in crease the risk of loss of control leading to
serious personal injury .
& WARNING (continued )
• Snow chains are available in different sizes. Alw ay s make sure
to follo w the instructions provided by the snow chain m anufac ­
turer .
• When driving with snow cha ins never drive faster than the
s peed permitted for your specific snow chains .
• Alway s observe lo cal regu lations.

Wheel bolts
Wheel bolts must always be tightened to the correct
torque.
The design of wheel bolts is matched to the factory installed rims. If
different rims are fitted, 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~
page 374.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving 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 wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss.
If the tightening torque of
the wheel bolts is too low, they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel bolts and threads can be damaged and the wheel can become
loose.
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
tolerance of ± 7,4 ft lb(± 10 Nm). Torque wheel bolts diagonally.
After changing a wheel, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under
a variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of 55 or
less in the tire's size designation. The numeral represents the ratio
of the tire's sidewall height in relation to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to improper inflation pressure. 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 pres­
sures should be checked at least once a month and always before a
long trip~
page 323, "Checking tire pressure" .
What you can do to avoid tire and rim damage Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehicle, we recommend that you observe the following
precautions:
• Always maintain recommended inflation pressures . Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully 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. ..,

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see . Damage can lead to loss of
air and underinflation, which could eventually cause tire failure . If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others.
• Please also remember that, while these tires deliver responsive
handling, th ey may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/cold season
conditions
All tires are design ed for certain purposes. The low aspect rat io ,
ultra high performance tires originally installed on your vehicle are intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If
you drive under those circumstances, you should equip your vehicle
with all -season or winter tires, which offer better traction under
those conditions . We suggest you use the recommended snow or
all -season tires specified for your vehicle, or their equivalent .
Refer to~
page 333for more detailed information regarding winter
tires. •
Tire pressure monitoring system
General notes U
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom ­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres- sure label, you should determine the proper tire i
nflation pressure
for those tires.)
As an added safety feature , your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly
under -inflated . Accordingly, when the low tire pressure telltale illu ­
minates, you should stop and check your tires as soon as possible,
and inflate them to th e proper pressur e. Driving on a signi ficantly
under-inflated tire causes the tire to overheat and can lead to tire
failure . Under-inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pr essure telltale.
Your vehicle has also been equipped with a TPMS malfunction indi ­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low tire pressure
telltale . When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously
illuminated . This sequence will continue upon subsequent vehicle
start -ups as long as the malfunction exists .
When the malfunction indicator is illuminated, the system may not
b e able to de tect or signal low tire pr essure as in tended. TPMS
malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction tell tale af ter replacing one or more
tires or wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function
properly. •
