General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
T ires may be the least appreciated and most abused parts of a
motor vehic le. Tires are, however, one of the most important parts
of a vehicle, particu lar ly considering the comparat ive ly sma ll patch
of rubber on each tire that assures that a ll-important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and i ts tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regular ly
inspecting tires for damage inc luding cuts, s lashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowou ts .
Av oiding d am ag e
If you have to drive over a curb or similar obstacle, drive very slowly
and as close as possible at a right angle to the curb.
A lways keep chemica ls including grease, o il, gasoline a nd brake
fluid off the tires.
I nspect the t ires regularly for damage (cuts, cracks or blisters, etc .l.
Remove any foreign bodies embedded in the treads.
Storing tire s
Mark tires when you remove them to indicate the direction of rota ­
t ion . This ensu res you to be ab le to mou nt them correctly w he n you
reinstal l them. When removed, the whee
ls or tires should be stored in a coo l, dry
and preferably dark place.
St ore tires in a vertical posit ion i f th ey are not mounted on r ims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in => &.
The tread dept h of new tires may vary, according to the type and
make of tire and the tread pattern .
Hidden damage
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or t he veh ic le pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an author ized Audi dealer or qualified workshop .
Unidire ction al tires
A unidirectio nal tire can be ide ntif ied by arr ows on the s idewa ll, t hat
point in the direction the tire is designed to rotate. You must fo llow
the specified direct ion of ro tation . This is necessary so t hat these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more info rmation
=> page 324.
& WARNING
Ne w tire s or tire s that are old , wo rn o r damaged cannot p ro vide
maximum control and braking abilit y.
• New tires tend to be slippery and mu st be brok en in . To redu ce
the ri sk of lo sing control , a c ollision and seriou s per sonal injuries ,
dri ve w ith special ca re for the fi rst 350 mile s (560 km l.
• Driving with worn or damaged tire s can lead to lo ss of control ,

• Extra care must be taken when rotating direction -specific tires
=> pag e 32 4.
Wheel balancing
T he wheels on n ew vehic les are bala nced. However, various situa ­
tions during eve ryday driving can cause them to become unba l­
ance d, res ulting i n vi brat ions you ca n us ual ly f eel thro ugh t he
steering whee l. U
nba lanc ed wh eels must be rebalanced to avoid excessive wear on
s tee ring, s uspen sio n an d tir es. A w heel m ust also be reba la nced
when a new tire is install ed.
Incorrect wheel alignment
Incorrect whee l alignment can cause excessive tire wear, impairing
t he sa fety o f the vehicl e. If ti res sh ow ex cessiv e w ear, h av e the
whee l al ignm ent check ed by an autho riz ed Aud i d eal er or qualifi ed
w ork shop.
All Wheel Drive
Ve hicl es wi th qu attr o® must alw ays h ave t ires of t he sa me siz e,
construction and tread type . For deta ils
see=> page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• Especially in wet and slick driving situations , a preferably large
profile depth of the tires is necessary , and an approximately
similar profile depth of the front and rear axle tires.
• The diminished driving safety , caused by too small of a tire
profile, is negatively perceivable especially in handling , in danger
of hydroplaning when driving through deep puddles and ponds,
when driving around curves , and in braking behavior.
• Worn tires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chem icals that can cause tire damage , such as
grease, oil, gasoline and brake fluid away from tires .
• 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 emergency and then with special care and at
lower speeds .

& 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 .
