2017 AUDI A6 tires

Wheels
&,. WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when
218
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­low enough air circulation to
cool the brake system. If they do not, this could increase the
risk of an accident.

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Dr iving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty chec k the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
i.

vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
The original tires on your vehicle
have 1/16 inch (1.6 mm) high
"wear indicators"¢
fig. 189 run­
ning across the tread. Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear in­
dicators .
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 ¢A.
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord-
~ l) Obey any applicable regulations in your 0
§ country.

Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden. Unusual vibrations in the
vehicle 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 deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.
A 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.

Checking/correcting tire
pressure
,..Check the tire pressure at least
once per month and also check it
before every long drive .
.,..Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
.,.Check the labe l¢
fig. 191 for
the correct tire pressure based
on vehicle load.
.,..Correct the tire pressure if nec­
essary .
.,..Store the new tire pressure in
the Infotainment system
¢ page 230 .
.,.Check the pressure in the emer­
gency tire* /spare tire*. A lways
maintain the maximum temper­
ature that is specified for the
tire.
A WARNING
Always adapt the t ire 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 safe­
ty precautions in ¢
page 223,
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 in­
creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident .
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.

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
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("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-
Wheels
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 Weight Rating
("GAWR") is the 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
carried 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 8-pillar
¢ page 220,
fig. 190.

A WARNING
Overloading a ve hicl e 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
i ncrease 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
tal load being transported -
i ncluding 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 total weight of the pas -
224
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed.
Steps for Determining Correct Load Limit
1. Locate t he statement "THE
COMBINED WE IGH T OF OCC U­
PANTS AND CARGO SHOULD
NEV ER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 220, fig . 190 .
2. Determine the combined
weight of the driver and pas­
sengers that will be r iding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 220, fig. 190.
4. The resu lting fig ure equals the
available amount of cargo and luggage load capacity. For ex ­
ample, if the "XXX" amount
equals 1400 lbs . and there will
be five 150 lbs . passengers in
your vehic le, the amount of
available cargo and luggage load capacity is 650 lbs . .,.

Wheel bolts and rims
Wheel bolts
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 multip le pieces . These compo­
n ents were bolted together using specia l bolts
a nd a special procedure . You must not repair or
d isassemble th em ¢.&. .
_& WARNING
Wheel bolts tha t are t igh tened or re paired in­
c orrectly can be come loose and result in loss
Wh eel s
of vehicle contro l, wh ich increases the risk of
an accident. For the cor rect tighten ing spec ifi­
cation, see
c:> page 238, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel 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 author ized Audi
Serv ice Facility. Never repair o r disassemb le
rims you rself, because th is increases the r isk
of an acc ident .
Winter tires
Winter tires signif icant ly imp rove the vehicle's
handling when dr iv ing in winter conditions. Be ­
ca use of their const ru ct io n (w idth, compou nd,
t read pat tern), summer tires provide less t rac ­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. Onl y use winter tires that a re approved fo r yo ur
veh icle .
.,. Please note that the maximum permitted
speed may be lower with winter tires
c:> _&. . An
author ized Audi dealer or authorized A udi Serv­
ice Facility can inform you about the maximum
permit ted speed for your tires.
.,. Check the tire pressure after insta lling wheels
c=> page220 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 in (4 mm) . T he characterist ics of winter
t ir es also decrease g reatly as the tire ages, re­
gardless of t he rema in ing t read.
_& WARNING
- Never drive fas ter than the max imum pe r­
mitted speed for your tires. This could c ause
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 conditions. 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 su mmer tires at the appropriate
time, because they pro vide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
@ Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries where w inter tires are required, only
w inter t ires with the
& symbol may be per­
m itted .
Snow chains
Snow chains not only imp rove the dr iving in w in ­
ter ro ad conditions, b ut also the brak ing .
.,. Only install snow chains o n the front wheels .
T his applies also to ve hicles w ith all wheel
drive* .
.,. Check and correct the sea ting of the snow
chains a fter dr iv ing a few fee t, if necessa ry. Fo l­
l ow the instructions from the manufacturer .
.,. Note th e maximum speed of 30 mph (SO km/
h). Note the loca l regulat ions.
Use of snow chains is on ly permitted with certain
rim/t ire combinations due to technical reasons .
Check with an authorized Audi dealer or author ­
i z ed Aud i Service Fac ility to see if you may use
snow chains.
You must remove the snow c hains on roads w it h ­
out snow. Otherw ise, you could impa ir dr iv ing
ab ility and damage the tires.
A WARNING
Us ing incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
cont rol, which inc reases the risk of an acc i­
dent .
(D Note
-Snow cha ins can damage the rims/wheel
covers* if the chains come into d irec t con­
tac t wi th them . Remove the wheel cove rs*
first. Use coa ted snow chai ns.
226
- Us ing snow c hains that add more than 0. 4
inch (10.S mm) of height can severely dam­
age the whee l housings and other vehicle
components .
- Do not insta ll and use snow chains if there is
a malfunction in the adapt ive a ir suspen­
sion*, because the vehicle he ight will be
very low. If you drive wit h snow chains any­
way, the whee l housings and other vehicle
components can be seve rely damaged .
(D Tips
When using snow chains, it may be useful to
switc h on sport mode

Low aspect ratio tires
You r A udi is factory-equ ipped with low aspect ra­
tio t ires . T hese tires have bee n thoroug hly tested
a n d been sele cted specifi ca lly for your mode l for
thei r sup erb pe rformance, road fee l and han dling
u nder a var iety of driving conditions. Ask your au ­
thori zed Audi dea ler for more detai ls .
The low as pec t rat io o f these tires is indica ted by
a n umera l of
55 or le ss in t he t ire's si ze designa ­
tion . The numeral represents the ratio of the
tire's si dewa ll height in relation to its trea d width
expressed in percentage. Conventiona l tires have
a height/width ratio of 60 or more.
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to improper inflation pres­
sure. It is the refore important that low aspect
rat io tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tir e pressur es should
be checked at lea st once a month and always
before a long trip
¢ page 220.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
l y by impact with potholes, curbs, gullies or
r idges on the road , particula rly if the tire is un -
der i nfla ted. .,..
