Wheel bolt s
Wheel bolts must be clean and loosen/t ighten
eas ily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo
nents were bolted together using special bolts
and a special procedure . You must not repair or
d isassemble them¢.&, .
A WARNING -
Wheel bolts that are t ightened or repaired in
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specif i
cation, refer to¢
page 284, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the whee l hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or d isassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inter tires significantly improve the veh icle's
handling when driving in winter condit ions . Be
cause of the ir construction (width, compound,
tread pattern), summe r tires provide less trac
tion o n ice and snow.
"' Use winter t ires on all fo ur wheels.
"' Only use winter t ires that are approved for your
vehicle.
"' Please note tha t the maximum permitted
speed may be lower with winter tires ¢
_&.. An
authorized Audi dealer o r authorized Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires.
"' Check the tire pressure after installing wheels
¢page 263.
Tires and wheel s
The effectiveness of winte r tires is reduced great
ly when the tread is worn down to a depth of
0.15 7 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re gardless of the rema in ing tread.
A WARNING
=
- Never drive faster than the max imum per
mitted speed for your tires. This could cause
the t ires to heat up too much. This increases
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions. Drive carefully and reduce
your speed on icy or slippery roads. Even
winter t ires can lose tract ion on black ice.
@) For the sake of the environment
Reinstall summer tires at the app ropr iate
time, beca use they prov ide bette r handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fue l
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires . Please note that in some coun
tries where winter tires are required, on ly
winter tires w ith the .& symbo l may be per
mitted.
Snow chains
Snow chains improve traction in the snow .
"'On ly install snow cha ins on the front wheels.
This applies a lso to vehicles with a ll w heel
drive* .
-
"'Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol
low the instructions from the manufacturer.
"' Note the maximum permitted speed when dr iv
ing with snow chains. Do not exceed 30 mph (50 km/h) .
Snow cha ins not o nly improve the
driving in win-
ter road condit ions, but also the
braking. Iii>

Tires and wheels
Use of snow chains is o nly pe rmitted with certain
rim/t ire combinations due to tec hnical reasons .
Chec k with an autho rize d Aud i dealer or autho r

Low aspect ratio tires
Your Aud i is fa cto ry-equippe d wi th low aspec t ra
tio tires . These ti res have been tho roughly teste d
an d been se lected specifically for yo ur model for
their superb per fo rmance, road f eel and handling
under a variety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re details .
The low aspect ratio of these t ires is indicated by
a nume ra l of
55 or less in the tire's size designa
tion . The nume ra l r ep resents the rat io o f th e
tire's sidewall he ight i n relat ion to its tread width
expressed in percentage . Conventional tires have
a height/w idt h ratio o f 60 o r more .
The performance of low-aspect-ratio tires is par
ticularly sensitive to improper inflation pres
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
c hecked and maintained . Tire pre ssures should
270
be checked at least once a month and always
before a long trip
~ page 263.
What you can do to avoid tire and rim
damage
Low aspect ra tio tires can be damaged more eas i
l y by impact with potho les, curbs, gullies or
r idges on t he road , particularly if t he tire is un
der i n flated.
I n order to min imize the occurrence o f impact
dama ge to the tires o f your veh icle, we recom
men d that you observe the following preca u
tions:
- Always main tain recommende d inf la tion pres
sures . Check yo ur tir e pressure eve ry 2,000
m iles (3,000 km) and add a ir if necessary .
- Dr ive ca refully on roa ds w ith potholes, deep
gullies o r ridges . The impact from dr iving
throug h or over such obstacles can damage
your t ires. Impact wit h a curb may a lso cause
damage to your tires.
-After a ny impact, immed iate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire 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 s ee . Damage ca n lead to loss o f air and
unde rin flation, w hich co uld even tually cause

Uniform tire quality grading
- Tr ead wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable on

For exampl e: T read wear 2 00 , Traction AA , Tem
perature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Trea d we ar
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under contro lled conditions on a specified gov
ernment test course.
For examp le, a tire graded
150 would wear one
and one ha lf
(11/2) times as well on the govern
ment course as a tire graded
100.
The relative performance of tires depends upon
the actual conditions of their use, however, and may d epart significant ly from the norm due to
variations in driving habits, service practices and d ifferences in road characteris tics and climate.
Tracti on
The traction grades, from highest to lowest, are
AA, A, B and
C. T hose grades represent the tire's
ability to stop on wet pavement as measured un
der controlled conditions on specified govern
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance

ii; The temperature grades are A (the h ighest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to diss ipate
Tir es and wheel s
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained h igh temperatu re can cause the mate
ria l of the t ire to degenerate and reduce ti re life ,
and excessive temperature can lead to s udden
tire failure
q .& .
The grade C corresponds to a level of perfo rm
ance which all passenger car tires must meet un
der the Federal Motor Vehicle Safety Standa rd
No.
109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minim um requ ired by law.
A WARNING
-
The tract ion grade assigned to this t ire is
based on straight -ahead braking traction
tests, and does not include acceleration, cor nering, hyd roplaning or pea k traction cha rac
terist ics.
A WARNING
The temperature grade for this tire is estab
lished for a tire that is properly infl,;1ted and
not overloaded . Excessive speed, underinfla
tion, or excessive loading, either separately or i n combination, can cause heat bui ldup and
possib le tire fai lure .
A WARNING

Tire pressure monitoring system
(l) General notes
App lies to vehicles: wi th tir e pressure mo nito rin g syste m
Each tire, including the spare (if provided),
shou ld be checked monthly when cold and inflat-
ed to the inflat io n pressure recommended by the
vehicle manufacturer on the veh icle placard or
t ir e inflation pressure label. (If your ve hicle has
t ir es of a different size than the si ze ind icated on .,..
271
Tires and wheels
the vehicle placard or tire inflation pressure la
bel, you should determine the proper tire
inflation pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell
tale when one or more of your tires is significant ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi
cantly under-inflated tire causes the tire 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
malfunction, the telltale will flash for approxi
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle 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
Applies to vehicles: with tire pressure monitoring 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. 206 Instrument cl uster: i ndic ator lig ht with message
Using the ABS sensors, the tire pressure monitor
ing system compares the tire tread circumfer
ence and vibration characteristics of the individu

pressure causes the tire to overheat and can
result in failure of the tire. Low pressure can
also have a negative effect on the driving
and braking behavior of the vehicle .
- Th e driver is responsible for maintaining the
correct tire pressures. You must check the
tire pressures regularly.
- Under certain conditions (such as a sporty
