-All four wheels must be fitted with radial
tires of the same type, size (rolling cir
cumference) and the same tread pattern .
Driving with different tires reduces vehi
cle handling and can lead to a loss of
control.
- If the spare tire 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 nor
mal road wheel as soon as safely possi
ble.
- Never drive faster than the maximum
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, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air
flow to the brakes can them to overheat,
increasing stopping distances and caus
ing 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. Incor
rect use of run flat tires can lead to vehi
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels . Mixing tire types is not permit
ted.

@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 284,
fig. 253.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •

288 Tires and wheels
The relative performance of tires depends
upon the actual conditions of their use, how
ever, and may depart significantly from the norm due to variations in driving habits, serv
ice practices and differences in road character
istics and climate.
Traction
The traction grades , from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢.&, .
Temperature
The tempera ture grades are A (the highest),
B, and
C, representing the tire's resistance to
the generation of heat and its ability to dissi
pate heat when tested under controlled condi
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure~.&, .
The grade
C corresponds to a level of perform
ance which all passenger car tires must meet under the Federal Motor Vehicle Safety Stand
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
A WARNING
The temperature grade for this tire is es
tablished for a tire that is properly inflated
and not overloaded . Excessive speed, un
derinflation, or excessive loading, either
-
separately or in combination, can cause heat buildup and possible tire failure.
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 all
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-wheel drive,
this will improve traction during winter driv
ing, even with the standard tires. However, we
strongly recommend that you always equip all
four wheels on your vehicle with correctly fit
ted winter tires or all-season tires, when win
ter road conditions are expected. This also im
proves the vehicle's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire sizes . Use
only radial winter tires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
O .15 7 inch
(4 mm).
Only drive with winter tires under winter con
ditions. Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7
°().
If you have a flat ti re, see notes on spare
wheel¢
page 284 .
Please always remember that winter tires may
have a lower speed rating than the tires origi-
nally installed on your vehicle at the time it .,.
Page 291 of 340

was manufactured. Please see ¢ page 285,
Speed rating (letter code)
for a listing of the
speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code (¢
page 2 76) is
on the side wall of the tire
c::> page 284.
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
tires leading to an acc ident and serious
pe rsonal inj ury to you and yo ur passen
gers .
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can ca use tire fai lure in
cluding a blowout and sudden deflation,
loss of control, crashes and serious per
sonal injuries . Have worn or damaged tires
replaced immed iately.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
wh ich the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac
celeration of the winte r tires and all-whee l
drive tempt you into taking extra r is k s . A l
ways remember:
- When bra king, an a ll-wheel drive vehicle
hand les in the same 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.
Tire s an d wheel s 289
'
@) For the sake of the env ironment
Use summer tires when weather condi
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be fitted only to the rear
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used.
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13.5 mm) , includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow cha ins on your vehicle
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are ava il
able from autho rized Aud i dealers.
A WARNING
Using the wrong snow chains for your vehi
cle or insta lling them incorrect ly can in
crease the risk of loss of cont ro l leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before dr iv ing 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 wheel rim , can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered. Check
the pos ition of the snow chains after

driving a few yards and correct if neces
sary. Follow the instructions from the
snow cha in manufacturer when doing so .
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex
tremely low. If you do dr ive with snow
chains on while the vehicle is at this lev
el, the snow chains might severely dam
age the wheelhouse and other parts of
the veh icle.
(!) Tips
Where snow cha ins are mandatory oncer
tain roads, this normally also applies to
veh icles with all-whee l dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If different rims are fit
ted, the correct wheel bolts with the r ight
l ength and correctly shaped bolt heads must
be used. This ensures t hat wheels a re fitted
secure ly and that the brake system f unctions
correctly .
I n ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
<=?page 318.
.&_ WARNING
Improperly tightened o r maintained wheel
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specified
torque. -
On ly use wheel bolts that be long to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct tightening
torque for the whee l bolts to reduce the
risk of a whee l loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is mov ing. If the tightening torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be
come loose.
(D Note
The specified torque for the wheel bolts is 120 ft lb ( 160 Nm) with a to le rance of
± 7,4 ft lb( ± 10 Nm) . T orque wheel bolts

Low aspect ratio tires
Your Audi is factory-equipped w ith low aspect
ratio tires. These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and hand ling under a variety of d riving condi
tions . As k your au thor ized A udi dealer for
more de tails .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or l ess in the tire's s ize
designation. The n umeral rep resen ts the ratio
of the tire's s idewa ll height in relation to its
tread width exp ressed in percentage . Conven
t iona l tires have a he ight/width ratio of 60 or
more.
The performan ce of l ow-a spect-r atio tire s is

¢ page 2 79, Checking tire pressure.
What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
easi ly by impact with potho les, curbs, gu llies
or ridges on the road, particularly if the tire is
underinflated.
I n order to minimize the occurrence 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 air if neces
sary.
- 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.
- After any impact, immediately inspect your
t ires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ir e as soon as possible .
- Inspect 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 ich could eventu
ally cause tire failure. If you be lieve that a
tire may have been damaged, replace the
tire as soon as possible.
- These tires may wea r more quickly than oth
ers.
- Please also remember that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices .
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes .
The low aspect ratio, ultra high performance
tires originally installed on your veh icle are in
tended for max imum dry and wet road per
formance and handling . They are not suitable
for cold, snowy or icy weather condit ions . If
Tires and wheels 2 91
you drive under those ci rcumstances, you
shou ld equip your vehicle with all-season or
winter tires, which offer better traction under
those conditions. We suggest you use the rec ommended snow or all-season t ires specified
for your vehicle, or their equivalent .
Refer to
¢ page 288 for more detailed infor
mation regarding winter tires .
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 manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s iz e indicated o n the vehicle placard or tire in
flat io n pressu re lab el, you sho uld determine
the p roper tire inflation pressure for those
tires).
As an added safe ty feature, your veh icle has
been equipped with a tire pressure monito ring
system ( TPMS) that illuminates a low ti re
pressure telltale when one or more of your
tires is significantly under-inflated. According
l y, when the low tire pressure te lltale illumi
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure . Driving on a sign ificantly un
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al
so reduces fuel efficien cy and tire tread life,
and may affect the vehicle's hand ling and
stopping ability .
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the leve l to tr igger illumination of the
T PMS low tire pressure tellta le .
Your vehicle has also been eq uipped with a
T PMS ma lfunction indicator to indicate when
the system is not operating properly. The
ll-
•

292 Tires and wheels
TPMS malfunction indicato r is combined with
the low tire pressure telltale . When the sys
tem detects a malfunct ion, the te lltale will
flash for approximately one minute and then
remain continuously illuminated. This se
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea
sons, includ ing the installat ion of replace
ment or alt ernate tires or wheels on the vehi
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunct ion
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 254 D isplay: underinflat ion wa rning
Using the ABS sensors, the tire pressure moni
toring system compares the tire tread circum
ference and vibration characteristics of the in
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instr u
ment cluster with a
[D] warning symbol and a
message ¢
fig. 254. The driver message in the
display goes out after S seconds. The driver
message can be displayed again by pressing
the

- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor
ty driving style, winter conditions or un
