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 safe­
ty precautions inc:::> page 295,
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
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­ ing, and the information is sub­
ject to change . If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8- pillar, always follow the specifica-

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 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.

-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)
c::> page 293, fig. 267 .
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
c::> page 293, fig . 267 .
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 ve­
hicle. Consult this manual to
determine how this reduces .,..

- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
autho rized Aud i dealer or authorized Aud i
Service Facility. Never repair or d isassemble
rims yourse lf, because this increases the risk
of an accident .
Winter tires
Winte r ti res s ignificantly improve the veh icle's
handling when d riving i n w inte r condit io n s. Be­
cause of the ir constr uction (width, compound,
t read pattern) , summe r ti res provide less trac ­
tion on ice and snow.
298
.,. Use win ter tires on a ll four wheels .
.. On ly use winter tires that are approved for yo ur
veh icle.
.,. Please note that the maximum permitted
speed may be lower with winter tires¢&_. An
author ized A udi dealer or autho rized Audi Serv ­
ice Fac ility can inform you about the maximum
permitted speed for your t ires .
.,. Check t he tire p ressure afte r insta lling wheels
¢ page 293 .
The effectiveness of wi nter tires is reduced g reat­
l y when the tread is wo rn down to a depth of
0.157 in ( 4 mm). The characte ris tic s of winter
ti res a lso decrease g rea tly as the t ire ages, re­
gard less o f the remaining t read.
_&. WARNING
- Never drive faster than the maximum pe r­
m itted 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 conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose t ract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropr iate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fuel
consumpt ion.
(i_) Tips
You can also use all season tires instead of
winter tires . Please note that in some coun­
tries where wint er tires are required, o nly
winter tires w it h t he

mi tted.
Snow chains

Snow chains not on ly improve the driving in win ­
ter road conditions, but a lso the braking .
.,. Onl y ins tall snow ch ain s on t he fro nt wheels. ..,.

~ Check and correc t the seating of the snow
chains after driving a few feet , if necessary . Fo l­
l ow the instructions from the manufacturer .
~ Note the maximum speed of 30 mph (SO km/
h). Note the loca l regulat ions.
Use of snow chains is on ly pe rmitted with certain
rim/tire combinations due to technical reasons.
Check w ith an authori zed Audi dealer or author­
ized Audi Service Fac ility to see if you may use
snow chains .
You must remove the snow chains on roads with­
out snow. Otherw ise, you could impair dr iving
ab ility and damage the tires.
_8 WARNING
Using incorrect snow chains o r 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 cha ins come into d irect con·
tact with t hem . Remove the whee l cove rs*
f irst. Use coate d snow chai ns.
- Using snow cha ins tha t add more than 0.4

age the wheel ho usings and other vehicle
componen ts .
- Do no t install and use s now chai ns if there is
a mal funct ion in the adaptive air suspe n­
s ion, because the vehicle heigh t will be very

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra-
o tio tires. These t ires have been thorough ly tested co
~ and been selected specifically for your model for ,.....
~ their supe rb performance, road feel and handli ng 0 0 :c ' Wh eel s
under a var iety o f dr iv ing condit ions . Ask your au ­
thorized Audi dea le r for more detai ls.
T he low aspect rat io of t hese tires is indicated by
a nu meral o f
55 or less in the tire's si ze des igna­
tion . The n umera l represents the ratio of the
tire's sidewa ll height in relation to its tread width
expressed in percentage . Conve ntiona l tires have
a height/width ratio of 60 or more .
The performance of low-aspect- ratio tires is par­
ti cula rly sen siti ve to imprope r inflation p res­
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 . Tire pressures should
be checked at lea st once a month and always
before a long trip
¢ page 293 .
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
ly by impact w ith potho les, curbs, gullies or
ridges on the road, particularly if the tire is un­
der inflated .
In order to m in imize the occurrence of impact
damage to t he tires of yo ur vehicle , we recom­
me nd tha t you observe the following preca u­
tio ns:
- Always maintain recommended inflat ion pres­
sures. Check you r ti re pressu re every 2,000
m iles (3,000 km) a nd add air if necessary.
- Dr ive carefully on roads w it h potholes, deep
gullies o r ridges. The impact from dr iving
t hrough or over such obst acles can damage
your tires. Impac t with a cur b may also ca use
damage to your tires.
- After a ny impac t, im med iate ly inspect yo ur
t ires or have them inspe cted by the neares t au­
t horized A udi dealer. Replace a damaged tire as
soon as possible.
- I nspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ich could event ually cause
tire fa ilure . If you believe that a tire may have
been damaged, replace the tire as soon as pos­
sible .
- These tires may wear more quickly than others . .,.

Wheels
- Please a lso remember that, wh ile these tires
deliver responsive handling, they may ride less
comfortably and ma ke more noise than other
cho ices.
Reduc ed performance in winter /cold s eason
condit ions
All tires are designed for certain purposes. The
low aspect ratio, ultra high performance t ires
or iginally i nstalled on your vehicle are intended
for maximum dry and wet road performance and
handling . They are not s uitable for cold, snowy or
icy weathe r cond itions.
If you drive under those
circumstances, you s hou ld equ ip your ve hicle
with a ll-season or win ter tires, wh ic h offe r bette r
traction under those con dit ions . We suggest you
use the recommended snow or all -season tires
specified fo r your vehicle, or their equivalent.

Temperature
The temperature grades are A ( the highest), B,
and C, representing the tire 's resistance to the
generatio n of heat and its ability to dissipate
heat when tested under contro lled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­

Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
veh icle manufact urer 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
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
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
p roper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys­
tem is not operat ing 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 mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal ­
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears

Description
App lies to : 58 plus
The tire pressure monitoring system monitors
the pressure in the four tires when driving .
The system uses sensors that measure the tem­
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency.
The Tire Pressure Monitoring System shows the current pressures and temperatures of the tires
in the Infotainment system
o page 304. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is stored
o page 304.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures.
- Every time the tire pressures change, for exam-
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used,
you must store the tire pressures again
opage 305.
A WARNING
--The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is high. This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
risk of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The Tire Pressure Monitoring System does
not warn you of damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
303

Storing new tire pressures
Applies to: S8 plus
Correctly stored tire pressure specifications are
necessary for reliable tire pressure monitoring .
.. Check the tire pressures in all wheels.
1> If necessary, correct the tire pressure according
to the spec ificat ions on the sticker on the driv ­
er's door ~
page 291 . Only correct the press ure
in tires whose tempera tu re is approx imately
the same as the amb ient temperature.
If the
tempera ture of the tire is highe r than the ambi­
ent a ir temperat ure, the tire pressure must be
increased approximately 3 PSI (0,2 bar) above
