& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always u se tires , rims and wheel bolts that meet the specifica ­
tions of original factory -installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergen cy and then with special care and at
lower speed s.
• Never mount used tires on your vehi cle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same type ,
size (rolling circumference ) and the same tread pattern. Driving
with different tires reduces vehi cle handling and can lead to a loss
of control.
• If the spare t ire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for wh ich the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cause heat build -up , sudden tire failure ,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For technical reasons it is not always possible to use wheel s
from other vehicles - in some cases not even wheels from the
same vehicle model.
& WARNING (continued )
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
s ystem that indicate s a loss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or ac cidents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equ ipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels . Mixing tire types is not permitted.
0 Note
• For tec hnical r eas ons, it is no t gene rally possible to use the
whee l rims from other vehicles . ihis can hold true for wheels of the
same ve hicle type.
• I f the spare tire is different from the tires that you have mounted
on y our ve hicle (f or exampl e wi nter t ires or wide p ro fi le tir es), then
use the spa re tire fo r a short per iod of time on ly and d rive with extra
c a re . Rep lace the flat t ire wi th the ti re m atc h ing t he oth ers o n you r
vehic le as soon as possib le .
• If yo u should put diff eren t w heels a nd tires on yo ur vehi cle (e. g.
winter wheels and tires), you must be certa in that the wheels and
t ires a re co mpatibl e w ith the tire press ur e m onit orin g sys te m.
Otherwise the system will regist er a ma lfunction and a fau lt
mes sage wil l be d isp layed . Fo r mo re info rmation, contact yo ur Audi

Winter tires
Winter tires can impr ove vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
I n some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread . These tires
should only be used in pairs and be instal led on a ll four wheels .
Make sure you purchase snow tires that are the same s ize and
construction type as the other tires on your vehicle .
If your vehic le is equipped with al l-wheel drive*, this will improve
traction during winter driving, even with the standard tires.
H owever, we strongly recommend that you a lways equ ip al l four
whee ls on your vehic le with correct ly fitted winter tires or all-season
t ires, when winter road conditions are expec ted. This also improves
t he vehic le's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow.
W inter tires (snow t ires) must a lways be fi tted on a ll four wheels .
If your vehicle is equipped with a tire pressure monitoring system* ,
compatible tire pressu re monitoring sensors must be instal led on
a ll f our winter t ires for the system to function
properly=> page 307.
Ask your authorized Audi dealer or qualified workshop for permitted
winter tire size s. Use only rad ial winter tires.
Winter tires lose their effect iveness when the tread is worn down to
a depth of 4 mm (0.157 inch).
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).
If you have a flat tire, see notes on spare
wheel=> page 305 .
Please a lways remember that winter tires may have a lower speed
rating than the tires original ly instal led on your vehicle at the ti me
it was manufactured . Please see
=> page 306 , "Speed rating (letter code)" for a listing of the speed rating letter codes and the
maximum speed at which t he tires can be d riven .
The speed rating letter
code(=> page 2961 i s on the side wa ll of the
tire => page 305.
& WARNING
Winter tire s have maximum speed limits that may be lower than
your vehi cle's ma ximum speed . Al wa ys know the ma ximum speed
before driving off . Never drive fa ster th an the speed permitted for
y our s pecifi c w inter tire s. Thi s will cau se damage to the tire s
lead ing to an a ccident and seriou s per sonal injury to you and your
p ass engers.
& WARNING
Driving fa ster th an the m aximum speed for whi ch the winte r tire s
on your vehi cle were de signed c an cause tir e failure in cluding a
blowout and sudden deflat ion , lo ss of contr ol, c rashe s and seriou s
per sonal injuries . Have worn or damaged tires repl aced immedi­
ately .
• Winter tires have ma ximum speed rating that may be lower
than your vehicle' s m axi mum speed .
• Never drive faster than the speed for which the winter or other
ti re s in sta lled on you r vehi cle are r ated .
& WARNING
Always adju st your driving to the ro ad and traff ic condit ions .
Never let the good acceleration of th e win ter tire s and all-wheel
dr ive tempt you into taking extra ri sks. Al ways rem ember :
• When braking, an all -wheel driv e vehicle handle s in th e same
w ay as a front dr ive veh icle .
• Drive ca refully and redu ce your speed on i cy and slippery r oads,
e ven w inter tires cannot h elp under bl ack ice condit ions .

Tires and wheels
----------------
&, WARNING (continued )
• Only u se wheel bolts that belong to the rim being installed.
• Never use different wheels bolt s on your vehi cle .
• Alway s maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel los s.
If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehi cle 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 (12 0 Nm) with a
tolerance of± 7,4 ft lb(± 10 Nm). Torque whee l bolts diagonally.
After changing a wheel, the torque must be c hecked as soon as
possible with a torque wrench -preferably by an authorized Audi
d ea ler or qua lifi ed works hop.•
Low aspect ratio tires
Your Aud i is factory -equipped with low aspect ratio tires . T hese tires
have been thorough ly tested and been selected specifical ly for your
mod el for t he ir superb perf or mance, r oad feel and ha ndling u nder
a variety of driving conditions . Ask your authorized Audi dealer for
mo re deta ils.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
i n the ti re's size designatio n. The numeral rep resents the ra tio
of the t ire's sidewa ll height in relation to its tread width expressed
in percentage . Conventiona l tires have a height/width ratio of 60 or
m ore.
The performan ce of low -aspe ct-ratio tires is part icularly sensitive to
improper inflation pressure . It is therefore important that low
aspe ct ratio tires are inflated to the specified pressure and that the
inflation pressure i s regularly checked and maintained. Tire pres- sures should be checked at least once a month and always before a
long
trip => page 299, "C heck ing tire pre ssure" .
What you can do to avoid tire and rim damage
Low as pect r ati o ti res can be da maged more easi ly by impact w ith
potho les, curbs, gullies or ridges on the road, particularly if the tire
i s u nde rinfl ated.
I n order to min imize the occurrence of impact damage to the t ires
of your vehic le, we recommend that you observe the fo llowing
precautions :
• Always maintain recommended inflation pressures . Check your
t ire pr essu re every 2,000 miles (3,000 k m) a nd add air if necessary .
• Drive careful ly on roads with potholes, deep gu llies or ridges.
T he im pac t from driving t hroug h or ov er suc h ob stacl es ca n
damage your tires. Impact with a curb may also cause damage to
yo ur tir es .
• After any impact, immediately inspect your tires or have them
inspec te d by the neares t au thori ze d Aud i dealer. Replac e a
damaged tire as soon as possible.
• I nspect you r ti res eve ry 2,0 00 m iles (3,000 km) for damage and
wear. Damage is not always easy to see. Damage can lead to loss of
a ir a nd und eri nfl ation, whic h cou ld eve ntual ly ca use tire fa ilur e. If
you be lieve that a tire may have been damaged, rep lace the tire as
s o on as p ossi ble.
• T hese tires may wear more quickly than others .
• P lease a lso remember that, whi le these tires de liver respons iv e
handling, they may ride less comfortably and make more noise t han
other choices.
