New tires or wheels
Audi recommends having all wo rk
on tires or wheels performed by
an authorized Audi dea ler or au­
thorized repair fac ility. These fa­
cilities have the proper knowledge
and are equipped with the re­
quired tools and replacement
parts.
.,. New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds fo r the first 350 miles
(500 km) with new tires .
.,. Use tires of t he same constr uc­
tion, size (rolling c ircumference)
and as close to the same tread pattern as possible on all four
wheels.

.,.Do not replace tires individ ually .
At least re place both t ires on the
same axle at the same time.
.,. A udi recommends that you use
Aud i O riginal equipment tires . If
you wo uld li ke to use different
tires, please note that the tires may perform d ifferently even if
they are the same s ize
c:> &. -
.,. If you would like to equip you r
vehic le with a tire/rim combina­
tion that is different from what
was installed at the facto ry, con ­
sult w ith an authorized Aud i
dealer or authorized repair facili­
ty be fore making a purchase
¢ .&_ .
The spare tire* is d ifferent from
the regular t ires installed on the
vehicle -for example, if winter
tires or wi de tires are installed -
then only use the spare tire* tem­
porar ily in case of emergency and
drive carefully while it is in use . It
s h o u ld be replaced w ith a regular
tire as soon as poss ib le.
On
all wheel drive ve hic les, all
four wheels must be equipped
w ith tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by

different tire speeds. For this rea­
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular tires.
A 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 6 years old when abso-
Wheels
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle . Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase 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 .

when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm .
... Check the label ¢

the correct tire pressure based on vehicle load.

essary.
... vehicles with Tire Pressure Moni­
toring System*: store the modi­
fied tire pressure in the Infotain­
ment system
¢page 252.
.,,.Check the pressure in the emer­
gency tire* /spare tire*. Always maintain the maximum temper­
ature that is specified for the
tire .
_& 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 245, 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

(D Note
Replace lost valve caps to re­

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehi cle
and any tire can carry. A vehicle that is overloaded will not handle
well and is more difficult to stop.
O verloading can not only lead to
loss of vehicle control, but can al­
so damage important part s of the
vehicle and can lead to sudden tire failure , including a blowout
and sudden deflation that can
c ause the vehicle to crash.
245

-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 - 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 total weight of the pas­
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 the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 243, fig. 19 7.
Wheels
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 243, fig . 197 .
4. The resulting figure 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 vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs .
(1400-750 (5 X 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­ ceed the available cargo and
luggage load capacity calculat ­
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehi­
cle. Consult this manual to de­
termine how this reduces the ..,

A WARNING
Whee l bolts t hat are tightened or repaired in­
co rrectly can become loose and resu lt in loss
o f vehicle control, which increases the risk of
an acc ident. For the correct tightening specifi­
cat ion, refer to
¢ page 2 56, 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 repa ired by an
autho rized Aud i dealer or authorized repair
facility. Never repair or disassemble rims
you rself, because this increases the risk of
an acciden t.
Winter tires
Winte r tires sign ificantly improve the ve hicle's
handling when d riving i n w inte r condit io ns. Be­
cause of the ir constr uction (wid th, compo und,
trea d patter n), s umme r tires p rov ide less tract ion
on ice and snow .
.,. Use w inte r tir es on all fou r wheels.
248
.,. On ly use winter tires that are approved fo r yo ur
vehicle.
.,. Please note that t he maxim um permitted
speed may be lower with winter tires ¢
_A .
Your authorized Audi dealer or authorized re­
pair faci lity can inform you about the maximum
perm itted speed for your ti res .
.,. Check the tire pressure afte r instal ling whee ls
¢ page 243.
The effect iveness of w inter t ires is red uced great ­
ly when the tread is worn down to a dep th of
0.1 57 i nch ( 4 mm). The cha racterist ics of winter
ti res a lso de crease grea tly as the t ire ages, re­
gardless of the remaining tre ad.
A WARNING
-
- Never drive faster than the max imum pe r­
m itted speed for your tires. This co uld 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 dr iving to the road and
traffic cond itions. D rive carefully and reduce
your speed on icy or slippe ry roads. Even
win ter t ires ca n 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
consum ptio n.
(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 a re requir ed, only win ­
ter tires w ith the£ symbol may b e permit­
ted.
' Snow chains
Snow chains improve traction in the snow .
.,. On ly install snow chai ns on the front w heels.
