Wheels
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and resu lt in loss
of vehicle control , which increases the risk of
an acc ident. For the correct tightening specifi­
cat ion, refer to
c:> page 261, After changing a
wheel.
- Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
- Only use wheel bo lts that fit the r im .
- Always have damaged rims repaired by an
authorized Aud i dealer or authorized repair
facility. Never repair or disassemble rims
you rself, because this increases the risk of
an accident.
Winter tires
W inter tires sign ificantly improve the vehicle's
handling when driving in w inter condit ions . Be­
cause of the ir construction (width, compo und,
tread pattern), summer t ires prov ide less traction
on ice and snow.
.., Use winte r tir es on all four whee ls .
.., Only use winter t ires that are approved for your
vehicle.
.., Please note that the maximum permitted
speed may be lower with winter tires
c:> .&,.
Your authorized Audi dealer or authorized re­
pai r facility can inform you about the maximum
permitted speed for your tires.
.., Check the tire pressure after installing wheels
c:> page 245.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1S7 inch (4 mm). The characteristics of w inter
tires also decrease greatly as the tire ages, re ­
gardless of the remaining tread.
A WARNING
-Never dr ive faste r than the maximum per­
mitted speed for your t ires. This could cause
the tires to heat up too much . Th is increases
the risk of an accident because it can cause
the tire to burst .
250
-Always adapt your driving to the road and
traffic cond itions. Drive carefully and reduce
your speed on icy or slippery roads. Even
w inter t ires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, beca use they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion.
(D Tips
You can a lso use all season tires instead of
winter tires. Please note that in some coun­
tries where w inter t ires are required, only win­
ter tires with the
& symbol may be permit­
ted.
· Snow chains
Snow chains improve traction in the snow .
.., Only install snow chains on the rear wheels .
.., Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instruct ions from the manufacture r.
.., Note the maximum permitted speed when dr iv­
ing w ith snow chains . Do not exceed 30 mph
(SO km/h) .
Snow cha ins not onl y improve the
driving in w in­
ter road conditions , but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons .
Check with a n author ized Audi dealer or author­
iz ed repair facility to see if you may use snow
c hains.
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in he ight, includ­
i ng the cha in lock.
You must remove the chains when driving on
roads that are
free of snow. When roads are free
of snow , snow cha ins can impair hand ling and
damage the tires, and the chains will quick ly be
destroyed. .,.

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra­
tio tires . These tires have bee n thoroughly tested
and been selected specifically fo r yo ur model fo r
the ir supe rb pe rformance, road feel and handling
u nder a va riety o f drivi ng conditions. Ask yo ur au­
thor ized Audi de aler for mo re det ail s.
The low aspect ratio of these tires is indica ted by
a numeral of
55 or less i n t he tire's si ze des igna­
tion . Th e nu mera l represents the rat io of the
tire's sidewall he igh t in relation to i ts tre ad wid th
expressed in percentage. Convent iona l tires have
a height/wi dth ratio of 6 0 or mo re .
The performan ce of low-a spe ct-rati o tires i s par­
ticularly sensitive to improper inflation pre s­
sure . It is therefore important that low a spect
ratio tires are inflated to the specified p ressure
and that the inflation pressure is regularly
checked and maintained. Ti re pressures should
be checked at least once a month and always
before a long trip
c:> page 245.
What you can do to avoid tire and rim damage
Low aspect ratio t ires can be damaged more easi­
ly by impact with potholes, curbs , gullies or
ridges on the road , par ticu la rly if the t ire is un­
de rinflate d.
In order to m inim ize the occurrence of impact
damage to the t ires of your vehicle, we recom­
mend that you observe the following precau­
tions:
Wheels
- Always ma inta in recommended inflation pres ­
sures. Chec k your tire pressure every 2,000
m iles (3,000 km) and add a ir if necessa ry .
- Drive carefully on roads with potholes, deep
gu llies o r ridges. T he impact from dr iving
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
thorized Audi dealer . Replace a damaged t ire as
soon as poss ible .
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is no t always
easy to see . Damage can lead to loss o f air and
un derinflation, wh ic h could even tually caus e
t ire failure. If you believe tha t a tir e may have
been dam age d, rep lace the t ire as soon as pos­
sible.
- These ti res may wear more quickly tha n oth ers.
- Please also remember that, wh ile these tir es
delive r respo nsive handling, they may ride less
c omfortably and m ake mo re no ise th an ot her
choices .
Reduced performance in winter/cold season
conditions
All tires a re designe d for cer ta in p urpo ses. The
l ow as pect ra tio, ultra high pe rformance tires
o rigi na lly installed on your vehicle are intende d
for maximum d ry and wet road performance and
handling. They are not suitab le f or co ld, snowy or
icy weather conditions. If you dr ive under those
c ircumstances, you shou ld equ ip your vehicle
with all-season or winter tires, wh ich offe r better
t raction unde r those co ndit ions . We suggest you
u se the recommende d snow or all-season tires
spe cified for your veh icle, o r th eir equiva le nt.
Refer to

t io n regarding w in te r tir es.
Uniform tire quality grading
- Tread wea r
- Traction AA A B C
- Temperature ABC
251

Wheels
Quality grades can be found where applicable on
the tire side wall between t read sho ulder and
maximum sect ion w idth
c::> page 235, fig . 204.
For example: Tr ead wear 200 , Tract ion AA, Tem­
peratu re
A .
All passenger ca r tires must confo rm to Federal
Safety Req uiremen ts in add it ion to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
unde r controlled conditions on a spec ified gov­
ernment test course.
For examp le, a t ire graded 150 would wear one
and one half ( 1 1/2) t imes as well on the govern­
ment course as a tire graded 100 .
The relat ive performance of t ires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations i n driving hab its, service practices and
d iffe rences in road character istics and clima te.
Traction
The traction grades, from highest to lowest, are
AA, A , Band
C. Those grades represent the tire's
ab ility to stop on wet pavement as measu red u n­
de r controlled cond it ions on spec ified govern­
ment test su rfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c::> &_ .
Temperature
The temperature grades are A (the highest), B,
a nd C, rep resent ing t he tire's res istance to the
genera tion of heat and its a bility to dis sipate
heat w hen tested unde r controlled cond itions on
a specified indoo r laboratory test whee l.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and red uce tire life,
a nd excessive tempera ture can lead to sudden
tire failure
c::> &. .
The grade C co rresponds to a level of perform­
ance wh ich a ll passenge r ca r tires m ust meet un­
de r th e Federal Motor Vehicle Safety S tandard
No. 109. G rades Band A represent higher levels
252
of pe rformance on the laboratory test whee l than
the minimum required by law .
A WARNING -
The traction grade assigned to th is tire is
based on straight-ahead braking tract ion
tests, and does not include acce lerat ion, cor­
nering, hyd roplaning or peak traction charac­
teristics.
A WARNING
The temperature g rade for th is tire is estab­
lished for a tire that is properly inf lated and
n ot ove rloaded. Excess ive speed, underi nfla­
tion, o r ex cess ive lo adi ng, eithe r separately or
i n comb inat io n, can ca use heat bu ild up and
possible tire failure.
A WARNING
Tempe ratu re grades apply to ti res that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
App lies to vehicl es: wi th tire p ress ure mo nito rin g system
-
Each tire, incl uding the spare (if provided),
sho uld be checked monthly when co ld and inflat­
ed to the inflat ion pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different s ize than the size indicated on
the ve hicle placard or t ire inflation pressu re la­
bel, you should dete rm ine the p roper t ire infla­
tion pressu re for those t ires).
As a n added safety feature, your ve hicle has been
equipped with a tire pressure mon itor ing system
( TP MS) that illum inates a low t ire pressure te ll-
ta le w hen o ne or mo re of yo ur ti res is sign ificant -
l y unde r-i nflated. According ly, w hen t he low t ire
pressure te lltale illuminates, you shou ld stop and
check yo ur tires as soon as possible, and inflate
them to the proper pressure . Dr iving on a signifi­
cant ly under-inf lated tire causes the t ire to over­
heat and can lead to tire failure. Under-inflation .,,.

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale . When the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent veh icle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle 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 replacement or alternate tires and
wheels allow the TPMS to continue to function properly.

If the Tire Pressure Monitoring System
indicator appears
Appl ies to vehicles : wi th t ir e p ress ure mo nito rin g system
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. 208 Instrument cluster: i ndicator light with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires .
If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
RIJ and a message
¢fig. 208. If only one tire is affected, the loca­
tion of that tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ¢
page 254. The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 245, fig . 207.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low .
- the tire has structural damage.
- the tir e was replaced or the tire pressure
changed and it was not stored again

- Pull the reversib le blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
- When mounting tires with
unidirectional
tread design
make sure the tread pattern is
pointed the right way
¢page 264.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of bot h the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When us ing a spare tire w ith a tread pattern in­
tended for use in a specific direct ion, please note
the following:
- The direction of rotation is marked by an arrow
on the side of the tire .
264
-If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora ­
r il y since the tire w ill not be ab le to achieve its
optimum performance character istics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay part icu lar atten­
tion to th is fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your veh icle as soon as possible to
resto re the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information ¢ page 242, New
tires ar wheels
if you are going to use a spare tire
which is different from the tires on your vehicle .
After you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
105 ft lb (140 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.
Until then, drive with extra care and at reduced
