We recommend that a ll work on tires and
whee ls be per formed by an authorized Audi
dealer. They are familiar with recommended procedures and have the necessary special
tools and spare parts as well as the proper fa­
cilities for disposing of the old t ires.
Authorized Audi dea lers have the necessary
information about technical requirements for
i nstalling or changing tires and rims .
Replacing tires and wheels
Tires should be replaced at least in pa irs and
not individually (for examp le both front tires
or both rear tires together) .
Be sure to read and heed the info rmation to
the tire pressure mo nitoring system
¢ page 246.
Always b uy replacement radia l tires that have
the same spe cifica tions as t he tires app rove d
for yo ur vehicle by Audi . Replacement tires
must a lways have the same load rating speci­
ficatio n as the origina l equipment or approved
optiona l tires listed in the table¢
page 232 .
Audi-approved specif ication t ires a re spec ial ly
matched to your vehicle and its load limits,
and can contr ibute to the impo rtant roadho ld­
ing, driv ing characteristics, and sa fety of the
vehicle. The table(¢

_& WARNING ,...__._
- Using incorrect or unmatched tires and/
or whee ls or improper tire and whee l
combinations can lead to loss of contro l,
co llision and serious persona l injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of original
factory-installed tires or other combina­ t ions that have been spec ifically ap­
proved 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 emergency
and then with special care and at lower
speeds .
- Never mount used tires on your vehicle if
you are not su re of their "previous histo­
ry." Old used ti res may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control.
- All four wheels must be fitted with radia l
tires of the same type, size (rolling cir­ c u mference) and the same tread pattern.
Driving with different tires red uces veh i­
cle handling and can lead to a loss of
control.
Tire s an d wheel s 241
-If the replacement tire is not the same as
the t ires that are mounted on the veh icle
- for example with winter tires - only use
the replacement tire for a short per iod of
time and drive with extra care . Refit the
normal road whee l as soon as safely pos­
sible.
- Never drive faster than the max imum
speed for which the tires on you r vehicle
a re rated because tires that are dr iven
faster than thei r rated speed ca n fa il
suddenly .
- Ove rloading tires ca use heat build-up,
sudden tire fa ilure, including a blowou t
and sudden deflation and loss of cont ro l.
- Temperature grades apply to ti res that
are properly inflated and not over or un ­
derinf lated .
- F or technical reasons it is not always
possible to use whee ls from other
vehicles -in some cases not even whee ls
from the same veh icle mode l.
- If you install wheel trim discs on the ve ­
hicle wheels, make sure that the air flow
to the brakes is not b locked. Reduced air­
flow to the brakes can them to overheat, increas ing stopping d istances and caus­
ing a co llision.
- Run flat tires may only be used on
veh icles that were equipped with them
at the factory . The veh icle must have a
chassis designed for run flat tires . Incor­
rect use of ru n flat ti res can lead to vehi­
cle damage or accide nts. Che ck with an
author ized Audi dealer or tire spe cialist
to see if your vehicle can be eq uipped
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 veh icles. Th is can hold tr ue for wheels
of the same vehicle type. .,..

24 2 T ire s and wheel s
-If a replacement tire is different from
the tires that you have mounted on your
vehicle (for example winter tires or wide profile tires), then use the replacement
tire for a short period of time only and
drive w ith extra care. Replace the flat tire
with the tire matching the others on your
vehicle as soon as poss ible.
- Never dr ive without the valve stem cap .
The valves could get damaged.
@ For the sake of the environment
Dispose of old t ires in accordance with the
local requ irements.
Uniform tire quality grading
- Tread wear
- Traction AA A BC
- Temperature ABC
Quality grades can be found where applicable
on the tire side wa ll between tread shou lder
and max imum section width
¢ page 239,
fig. 199.
For example: Tread wear 200 , Traction AA,
Temperature A.
All passenge r car tires must confo rm to Feder ­
a l 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
u nder cont rolled conditions on a spec ified
government test course .
For example, a t ire graded 1S0 wou ld wear
one and one half (11/ 2) t imes as well on the
gove rnment course as a tire graded 100.
The relat ive perfo rmance of t ires depends
upon the a ctua l conditions of their use, how ­
ever, and may depart sign ifican tly from the
n orm due to var iat ions in dr iving habits, serv­
ice practices and differences in road cha racte r­
istics and climate .
Traction
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the
ti re's ability to stop on wet pavement as
measured under contro lled conditions on
specified government test surfaces of aspha lt
and concrete. A t ire marked C may have poor
traction performance ¢.&,. .
Temperature
The temperature grades are A (the highest),
B, and C, representing the tire's resistance to
the generation of heat and its ab ility to dissi­
pate heat when tested under controlled condi­
t ions on a specif ied indoo r laboratory test
wheel.
Sustained h igh temperature can cause the
mater ial of the tire to degenerate and reduce
t ire life, and excessive temperature ca n 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 h igher
levels of performance on the laborato ry test
whee l than the minimum requ ired by law.
_& WARNING
The t raction grade assigned to t his tire is
based on s traight-ahead braking trac tion
tests, and does not include accelerat ion,
cornering, hydroplaning or peak t raction
cha racte rist i cs.
A WARNING "--
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excess ive speed, un­
derinflation, or excess ive load ing, either
separately or in combinat ion, can cause
heat bui ldup and possib le tire failure.

Winter tires
Winter tires can improve vehicle handling on
snow and ice . At temperatures below 45 °F
(7 °C) we r ecommend changing to winter
tires.
In some heavy s now areas, local governments
may require true winter or "snow " tires, those
with ve ry deeply cut tread. These t ires shou ld
only be used in pa irs and be insta lled on all
fou r wheels. Ma ke sure yo u pu rchase snow
tires that are the same size and construction
type as the other tires on your vehicle .
Your veh icle is equipped w it h all-wheel drive,
this will improve tra ct io n du ring w inte r driv­
ing, even with the s tandard tires. However, we
strongly recommend that yo u always eq uip a ll
four whee ls on your vehicle with cor rectly fit­
ted w inter tires or all-se ason tires, when w in ­
te r r oad conditions are expected . This also im­
proves the vehicle's braking performance and
reduces stopping distances .
Summe r tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must a lways be fitted
on all four whee ls .
Ask yo ur autho rized Aud i dea ler o r qualified
wo rkshop fo r permi tted
winter tire siz es . Use
on ly radia l winter tires.
W inte r tir es lose the ir effectiveness when the
tread is worn down to a depth of 0.15 7 inch
(4 mm) .
Only drive with wi nter tires under winter con­
d it ions . Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above 45 °F ( 7 °C).
I f you have a flat tire, see notes on replace­
men t wheel ¢
page 239.
Please always remember that w inter tires may
h ave a lower speed rating than the t ires origi­
n a lly installed on your veh icle at the t ime it
was manufactured. Plea se see ~
page 240,
Speed rating (letter code)
for a List ing of the
speed rat ing letter codes and t he maxim um
speed at w hic h the tir es can be driven.
Tire s an d wheel s 243
The speed rating letter code(¢ page 231) is
o n the side wall of the tire~
page 239 .
A WARNING
Winter t ires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the max imum
speed before driv ing off . Never drive faster
than the speed permitted for yo ur specific
winter tires . This wi ll ca use damage to the
tires leadi ng to an accident and ser ious
personal injury to you and your passen­
gers .
A WARNING ,._.__
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fail ure in­
cluding a blowout and sudden deflation, loss of contro l, crashes and ser ious per­
sonal injuries. Have worn or damaged tires
replaced immediately .
- Wi nter tires have maximum speed rating
that may be lower than your vehicle 's
maximum speed .
- Never drive faster than the speed for
which the w inter or othe r tires installed
on you r vehicle a re rated .
A WARNING
Always a djust yo ur dr iv ing to the road and
traffic cond it ions . Never let the good ac­
celer atio n of the winter t ires and al l-wheel
d rive tempt yo u into ta king ext ra risks. Al­
ways remember:
- W hen braking, an all-wheel drive veh icle
handles in the same way as a front drive
vehicle .
- Drive c arefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
@ For the sake of the environment
Use summer tires when weather condi­
tions permi t. T hey are qu iete r, do not wear
as quickly and reduce fuel consumpt ion .

risk of a wheel loss . If the tightening tor­
que 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 whee l bolts and threads
can be damaged and the wheel can be­
c ome loose.
(D Note
The spec ified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of ± 7,4
ft lb(± 10 Nm) . Torque wheel bo lts d iago­
na lly . After chang ing a wheel, the torque

Low aspect ratio tires
Your Audi is factory-equipp ed with low aspect
ratio t ires. These t ires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
and handling unde r a va riety of driving condi­
tions. Ask your a uthorized Aud i dea le r fo r
mo re deta ils.
T he low aspect ratio of these tires is indicated
by a nume ral of
55 or less in the tire's size
des ignation . T he numeral represents the rat io
of the ti re's sidewall height in relat io n t o its
tread wid th expressed in per cen tage . C o nven­
tional t ires have a height/width ra tio of 60 or
mo re.
Th e performan ce of low -aspe ct-ratio tir es is
parti cularl y se nsitive to improper inflation
pressure . It is therefore impor tant that low
a s pect ratio tire s are inflated to the specified
pressure and that the inflation pre ssure is
regularly checked and maintained. Ti re pres­
sures should be checked at least once a
month and always before a long trip
c::> page 234, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
eas ily by impact with potho les, curbs, gu llies
Tire s an d wheel s 245
or r idges on the road, partic ularly if the tire is
u nderinflated.
In orde r to minimize t he occ urren ce of impact
dam age to the tires o f your vehi cle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma int ain re commended inflation
pressu res . Check your tire pressu re eve ry
2,000 miles ( 3,000 km) and add air if neces ­
sary.
- Dr ive ca re fu lly on roads with potholes, deep
gullies o r 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, immed iate ly inspect your
tires or have them inspected by the nearest
au thor ized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 m iles (3,000
km) for damage and wear. Damage is no t al­
ways easy to see . Damage can lead to loss of
air a nd under inflat ion, which could eventu­
ally cause tire failure .
If you believe that a
t ire may have been damaged, rep lace the
t ire as soon as possib le.
- These tires may wear more quickly tha n oth­
ers.
- Please also remember that, while these tires
de live r respon sive handling, they may ride
less comfo rtably and m ake more noise tha n
other choi ces .
Reduced performance in winter /cold
season conditions
A ll ti res are designed for cer ta in p urposes.
T he low aspect ratio, ult ra h igh performance
tires originally installed on your vehicle are i n­
tended for maxim um dry and wet road per­
f ormance and handling. They are not suitable
for cold , snowy or icy weather condi tions. If
you drive under those circumstances, you
shou ld equ ip your vehicle w it h all -season or
winter tires, which offer bette r traction under
those conditions. We suggest you use the rec­
ommended snow o r all-season t ires specified
f o r yo ur vehicle , or t hei r equivalent . .,..

Tire pressure
monitoring system
(D General notes
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in­
flated to the inflation pressure recommended 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 in­
flation pressure label, you shou ld determine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
p ressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the proper pressure. Driving on a significantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure . Under -inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped w ith a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunction, 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 illum inat­
ed, the system may not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re­
placement o r alternate ti res and wheels allow
the TPM S to cont inue to function properly.
Description
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the
temperature and pressure in the tires. Theda­
ta is sent from these sensors to the control
module by radio frequency.
The tire pressure monitoring system shows
the current pressures and temperatures of the
tires in the Infotainment system
¢page 247.
It also compares the current tire pressures
with the stored pressures and gives a warning in the driver information system if the tire
pressure is different from what is stored
¢ page 247.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must resave the tire pressures
¢page 248:
- eve ry time the tire p ressu res change, for ex­
ample when the load in the vehicle changes,
- after replacing a t ire, or
- if wheels w ith new wheel sensors are used .
_&. WARNING
-The tire pressu re monitoring sys tem as­
sists the driver in monitoring tire pres­
sures. The driver is responsible for having
the tires inflated to the correct pressure. ..,.

252 What do I do now?
(D Note
Do not use commerc ia lly available tire
sealants . The electrical components of the
tire pressure mon itoring system will no
longer work properly.
@ For the sake of the environment
Used sealant bottles can be dropped off at
a recycl ing facility.
@ Tips
- If sealant has run out, allow it to dry.
Then you can peel it off.
- Have the tire sealant replaced every 4
years at a dea lership.
Preliminary steps
Some preliminary steps ore necessary for tire
repair.
.,. If you have a fla t t ire, park the veh icle as far
as possible from moving traffic.
.,. Apply the
parking brake firmly .
.,. Move the
selector lever to the P position .
.,. Check whether a repair using the Tire Mobili­
ty System is possible Q page 251, General
and safety pointers .
.,. Have all passengers leave the vehicle and
stay away from the danger zone
q ,& .
.,. Take the s ealant bottle and the electric air
pump
from the luggage compartment un­
der the floor.
.,. Remove the "max . SO mph" (80 km/h) stick­
er from the sealant bottle and aff ix it to the
instrument cluster in the driver's view .
A WARNING
-Turn the hazard flashers on and set up
the warning triangle* if you have a flat
tire in moving traffic. In this way you pro­
tect you rs elf and other road users .
- Make sure that all passengers are in a
safe place, out of the danger zone (for
example, behind a guard ra il).
