Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized repair facility
check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 inch (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion
c:> fig. 170. The letters "TWI"
or triangles on the tire sidewall
indicate the location of the tread­
wear indicators.
;;; l) Obey any applicable regulations in your "?
~ country . .....
Wheels
The tires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
c:> .&. .
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly . To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice ver­
sa. This will allow the tires to
have approximately the same
length of service life.
For unidirectional tires, make sure
the tires are installed according to
the running direction indicated on
the tire sidewall
c:> page 223.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hid­
den. Unusual vibrations in the ve­
hicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi
205

Wheels
dealer or authorized repair facility
to have the vehicle inspected.
&_ WARNING
Tread that has worn too Low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the
risk aquaplaning when driving
through water, when driving
through curves and when brak­
ing, which increases the risk of
an accident.

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important
safety precautions in
¢ page 208, Tires and vehicle
load limits.
-The tire must flex more if the tire pressure is too low or if the vehicle speed or load are
too high. This heats the tire up too much. This increases the
risk of an accident because it
can cause the tire to burst and result in loss of vehicle con­
trol.

-Incorrect tire pressure increas­
es tire wear and has a negative
effect on driving and braking behavior, which increases the
risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash .
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev-
208
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle , all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load . The maxi ­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci ­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer hitch and the tongue weight of
the loaded trailer must be includ- ed as part of the vehicle load. ..,.

The Gross Axle W eight R ating
("GAWR") is t he maximum load
that can be applied at each of the
vehicle's two axles .
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carr ied in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen ­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 206,
fig .171 .
A WARNIN G
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury , and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in-
Wheels
crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
- Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash .
- Always make sure that the to­
ta l load being transported -
including the weight of a trail ­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the tota l weight of the pas­
sengers and luggage or other
things that you plan to transpor t
so that you can make sure that
your vehicle will not be overload- ed.

Winter tires
W inter tires sign ificantly improve t he vehicle's
h andling when drivi ng in winter condit ions. Be­
cause of the ir construction (width, compound,
tread pattern), summer t ires p rov ide less t ract ion
on ice and snow.
.. Use w in ter t ires on all four wheels.
.. Only use winter tires that are approved for your
vehicle .
" Please note that the maximum permitted
speed may be lower w it h w inter tir es ~,&. .
You r authorized Audi dea le r or a uthorized re­
pair facility can in form you about the maximum
permitted speed fo r yo ur tires.
.. Check the tire pressure after insta lling wheels
~ page 206.
The effectiveness of winte r tires is reduced great ­
l y when the tread is worn dow n to a depth of
0 .157 inch (4 mm). The characteristics of w inter
tires also decrease greatly as the tire ages, re­
gardless of the remai ning tread .
A WARNING
-Never drive faster than the maximum per ­
mitted speed for your t ires. This could cause
the tires to heat up too much . This increases
the risk of an ac cident be cause it can cause
the tire to b urst.
- Always adapt you r driv ing to the road and
t raff ic conditions. Dr ive ca refully and re duce
yo ur speed on icy or slippery roads. Even
w inter tires can lose tract ion on black ice.
@ For the sake of the environment
Reinstall summer tires at the approp riate
t ime, because they prov ide be tter h and ling
when roads a re free of snow and ice. S ummer
tires ca use less road no ise, tire wea r and fuel
consumption.

{!) Tips
You can also use a ll season tires instead of
winter tires. P lease note that in some coun­
tries where w inter tires are required, only win­
ter tires w ith the
& symbol may be permit­
ted.
Snow chains
Snow chains improve traction in the snow .
.. On ly install snow chains on the front wheels .
T his applies a lso to vehicles with a ll whee l
drive .
.. Check and correct the seating of the snow
chains if necessary after driving a few feet . Fol ­
low the instructions from the manufactu rer .
.. Note the maximum permitted speed when dr iv­
ing wit h snow chains . Do not exceed 30 mph
(SO km/h).
Snow c ha ins not only improve the
driving in w in­
te r road cond itions , but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons .
Check with an authorized Audi dea ler or author­
ized repa ir fac ility to see if you may use snow
chains.
Use
fine-mesh snow chains. They must not add
more than 0 .41 inch (10 .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 handl ing and
damage the tires, and the chains wi ll quickly be
dest royed.
A WARNING
Using incor re ct snow chains o r insta lli ng snow
cha ins incorrect ly can result in loss of ve hicle
control, which increases the risk of an acci­
dent .

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra­
tio tires. These tires have been thoro ughly tested
a nd been se lected specifically fo r yo ur model for
their superb per formance, road feel a nd handling
un der a va riety of d riving conditions. Ask you r au ­
thor ized Audi dealer for more deta ils.
The low aspect ratio of these tires is indicated by
a numeral of
55 or less i n the tire's size des igna­
tion . Th e nu mera l re p resen ts th e r atio of t he
tire's sidewall he igh t in relation to i ts trea d w idt h
e xpres sed in per centage. Convent io na l ti res h ave
a heig ht/w idth ra tio of 6 0 or mo re.
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 pre ssure is regularly
checked and maintained. Tire pressu res should
be checked at least once a month and always
before a long trip<=> page 206.
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
r idges on the road, part icu larly if the t ire is un­
de rinflated .
In order to m inimize the occu rrence o f impact
damage to the t ires of your vehicle, we recom ­
mend that y ou obse rve the following precau­
tions:
- Always maintain recommende d inflation pres­
s u res. Check your tire press ure eve ry 2,000
miles (3,000 km) and add air if necessary.
- Drive carefully on roads w ith po tholes, deep
gull ies or r idg es. The impact from d rivin g
t hr ough or over such obstacles can damage
yo ur tires. Impact w ith a curb may also cause
damage to you r ti res .
- After any impact, im mediately inspect your
t ir es or have th em inspected by the neares t au-
212
thori zed A udi d ealer. Re place a damaged t ire as
soo n as possible .
- Inspe ct your tires every 2, 000 m iles (3,0 00 km)
for damage and wear. Damage is not always easy to see. Damage can lead to loss of air and
unde rinflation, wh ic h co uld event ua lly cause
tire failure. If you believe t hat a t ire may have
been damaged, rep lace the t ire as soon as p os­
sible .
- These tires may wea r more quickly than others.
- Please also remember t hat, while these t ires
delive r responsive handling, they may r ide less
comfortably a nd make mo re noise than othe r
choices.
Reduced performance in winter/cold season

under controlled conditions on a specified gov­
ernment test course.
For example, 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 depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics 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 un­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete . A tire
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 ability to dissipate heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial 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 un ­
der the Federal Motor Vehicle Safety Standard 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 stra ight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplan ing or peak traction charac­
teristics.
Wheels
A WARNING
The temperature grade for this tire is estab­ lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in comb ination , can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tir es that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill General notes
Applies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed 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 inflation pressure la­
bel, you should determine the proper tire infla­
tion 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 shou ld stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cant ly 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. .,.
213

Wheels
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 veh icle start-ups as long as the mal­
function ex ists.
When the malfunct ion 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, incl uding the
installation of rep lacement or a lternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction tellta le 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.
