Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regu lar ly
inspecting tires for damage inc luding cuts , slashes 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 lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota ­
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information

___ T_ ir_e_ s _ a_ n_d_ w_ h_ e_e _ l_s _________________________________________________ _
& WARNING
• Using incorrect or unm atched t ires and / or wheels o r improper
tire and wheel combinations can lead to lo ss of control , collision
and se rious per sonal injury .
• Always use tires , rim s and wheel bolts that meet the specifica ­
t ions of original f actory -installed tire s or other combinations that
have been spe cifically approved by the vehicle manufacturer .
• T ires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old c an
only be used in an emergen cy and then with spec ial care and at
lower speeds .
• Never mount used tires on your vehi cle if you are not sure of
their "previou s history." Old used tires may have been damaged
e ven though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted w ith radial tires of the same type ,
size (rolling circumference ) and the same tread pattern . Driving
with different tires reduces veh icle 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 e xtra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build -up , sudden tire failure,
in cluding a blowout and sudden deflation and lo ss of control.
• Tempe rature grades apply to tires that are properly inflated and
not over or under inflated .
• For technical reasons it i s not always po ssible to use wheel s
from other veh icles - 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 cha ssis designed
for run flat tires and a fa ctory-installed tire pressure monitoring
system* that indicates a loss of tire pressure. Incorrect use of run
flat tires can lead to vehicle damage or acc idents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equ ipped with run f lat tires . If run flat t ires are used , they must
be installed on all four wheels . Mixing tire types is not permitted.
0 Note
• For technical r eas ons, it is not gen erally possible t o us e the
whee l rims from other veh icles . ihis can ho ld true for whee ls of the
same veh ic le type.
• I f the spare tire is different from the tires that you have mounted
o n yo ur vehicl e (f or example wi nter tires or wide p rofile t ires), then
use the spare tire for a short period of time on ly and drive with extra
care . Rep lace the flat tire wi th the ti re m atchi ng t he o thers on you r
vehic le as soon as possib le.
• I f you should put diff ere nt w heels and tires o n your v ehicle (e. g.
winter wheels and tires), you must be certain that the wheels and
t ires are c ompatib le wi th the tire p ressu re monitoring system* .
Otherwise the system will register a malfunction and a fau lt
mes sage will be displayed . For more info rmation, contact your
author ized Aud i dea ler.

Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires .
In 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 installed on a ll four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
Your vehicle is equipped with all -whee l drive, this wi ll improve trac ­
tion during winter driving, even with the standard tires. However,
we strong ly recommend that you a lways equip all four whee ls on
your vehicle with correctly fitted winter tires or all-season tires,
when winter road conditions are expected. This also improves the
vehicle's braking performance and reduces stopp ing distances.
Summer tires provide less grip on ice and snow.
Winter tires (snow ti res) must a lways be fitted on a ll four wheels.
Compatible tire pressure monitoring sensors must be installed on
a ll fou r winter tires for the tire pressure monitoring system* to func ­
tion proper ly=>
page 301.
Ask your authorized Audi dealer or qualified workshop for permitted
wint er tire size s. Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to a depth of 0.157 inch (4 mm).
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C) .
If you have a flat tire, see notes on spare wheel =>
page 299.
Please always remember that winter tires may have a lower speed
rat ing than the tires originally installed on your vehicle at the time
it was manufactured. Please see=>
page 300, "Speed rating (letter code)" for a listing of the speed
rating letter codes and the
maximum speed at which the tires can be driven .
T he speed rating letter code(=>
page 290) is on the side wall of the
tire =>
page 299.
& WARNING
Winter tire s hav e maximum speed l imit s that m ay be lower than
yo ur veh icle' s ma xim um speed . Al ways kno w the ma ximum speed
before driving off . Never drive fa ste r th an the speed permitted for
yo ur spe cifi c w inte r tir es. Thi s will cause dam age to the tire s
leading to an a ccident and seriou s personal injury to you and your
p as sengers.
& WARNING
Driving f aster th an the m aximum speed for whi ch t he winter tire s
on your v ehi cle w ere de sig ned can cau se tire failur e including a
blow out and sudden def lation , lo ss of con trol, c rashe s and se riou s
personal injuries . Have worn or damaged tire s repl aced immedi­
ately .
• Winter tires hav e maximum speed r ating that may be lower
than you r vehicle 's maxi mum speed .
• Never d riv e fa ster than the sp e ed for which the winter or other
tire s in sta lled on your vehicl e are r ated .
& WARNING
Always adju st your dri ving to the r oad and tr aff ic c ondit ions .
Ne ver let th e good acceleration of the winter tire s and all -wheel
dri ve t empt you into t aking extra risks. Alw ay s rem embe r:
