2018 AUDI A8 winter tires

u. co .... N
" N .... 0 0 :c ' ~ Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
~ Note the maximum speed of 30 mph (SO km/
h). Note the loc al regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authori zed Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains .
You must remove the snow chains on roads with­
out snow. Otherwise, you could impair driving
ability and damage the tires.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
0 Note
-Snow chains can damage the rims/wheel
covers* if the chains come into direct con·
tact with them . Remove the wheel covers*
first. Use coated snow chains.
-Using snow chains that add more than 0.4
inch (10.5 mm) of height can severely dam­
age the wheel housings and other vehicle
components.
-Do not install and use snow chains if there is
a malfunction in the adaptive air suspen­
sion, because the vehicle height will be very
low. If you drive with snow chains anyway,
the wheel housings and other vehicle com­ ponents can be severely damaged.
@ Tips
When using snow chains, it may be useful to
switch on sport mode

Low-profile tires
Appl ies to: ve hicles w ith low-profile tires
Your vehicle is equipped with low-profile tires* at
the factory . Compared to other tire/rim combina­
tions, low-profile tires offer a wider tread surface
and a larger rim diameter with shorter tire side-
Wheels
walls. This results in an agile driving style. How­
ever, it may reduce the level of comfort and in­
crease road noise when driving on roads in poor
condition.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, speed
bumps and curbs. Therefore, it is particularly im­
portan t to maintain the correct tire pressure
¢ page 293.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authori zed Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires.
Summer tires are not suitable for cold weather,
snow or black ice. If you are driving in these con­
ditions, use winter or all season tires
¢ page 298.
Uniform tire quality grading
-Tread wear
-Traction AA AB C
-Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width
¢ page 283, fig. 264.
For example: Tread wear 200, Traction AA, Tem­
perature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
299

Wheels
-The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the tire pressure monitoring system
indicator may be delayed .
- Do not use run-flat tires on your vehicle. Us­
ing them when not permitted can lead to
vehicle damage or accidents .
(D Tips
- The tire pressure monitoring system can al­
so stop working when there is an ESC mal­
function .
- Using snow chains may result in a system
malfunction.
- The tires with the identification
"AO" or
"RO" ¢ page 290 have been matched with
your Audi tire pressure monitoring system.
Using these tires is recommended.
Storing tire pressures
Applies to: AB, S8
If the tire pressure changes or a tire is replaced,
it must be confirmed in the Infotainment sys­
tem .
.,. Make sure before storing that the tire pressures
of all four tir es meet the specified values and
are adapted to the
load ¢ page 291 .
.,. Switch the ignition on .
.,. Select : the ICARI function button > Car Systems
control button > Service & control > Tire pres­
sure monitor> Store tire pressure > Yes, store
now.
(D Tips
Do not store the tire pressures if snow chains
are installed. Otherwise the system could
malfunction.

Tire Pressure Monitoring System (SB plus)
ill General notes
Applies to: S8 plus
Each tire, including the spare (if provided),
shou ld 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 ind icated on
the veh icle placard or tire inflat ion 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 mon itor ing system
(TPMS) t hat illuminates a low tire pressure tell­
ta le when o ne or more of your tires is significant­
l y under-inflated. According ly, 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 ­
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
spons ibility to maintain correct t ire pressure,
even if under-inflation has not reached the level
to trigge r illumination of the TPM S low t ire pres­
su re te lltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to ind icate when the sys­
tem is not operating prope rly . The TPM S mal­
function indicator is combined with the low t ire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence wi ll 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

Emergency assistance
There are some restrictions on the use of the
spare tire. The spare tire has been designed spe­
cifically for your type of vehicle. Do not replace it
with the spare tire from another type of vehicle.
There are different types of spare tires available
depending on the equipment
c::> page 320.
Removing the spare tire
• Lift the cargo floor by the plast ic ha ndle
c::> fig. 282.
• Hook the hand le into the luggage compartment
weathe r strip.
• Turn the handwheel counter-clockwise and re-
move it.
• Remove the spare tire.
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive w ith snow chains and a front
tire fails , mount the spare t ire in place of a rear
tire . Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.
A WARNING
-After installing a spare tire, the tire pres­ sure must be checked as quickly as possible.
- Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
- To reduce the risk of an accident, avoid full­
throttle acceleration, heavy braking, and
fast cornering with the compact spare t ire.
- To reduce the risk of an accident, never drive
with more than one compact spare tire.
- Norma l summer or winter tires must not be
mounted on the compact spare wheel rim.
A WARNING
- Never use the spare tire if it is damaged or if
it is worn down to the tread wear indicators.
- If the spare tire is more than 6 years old, use it only in an emergency and with ex­
treme caution and careful dr iving .
- The spare tire is intended only for tempora­
ry and short-term use.
It should be replaced
320
as soon as possible with the normal whee l
and tire.
- For technical reasons, the use of tire chains
on the spare tire is not permitted. If it is
necessary to drive with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire . The newly
ava ilable front wheel must then be installed
in place of the rear wheel w ith the flat tire.
Installing the tire chain before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment
can cause serious personal injury during
hard braking or in an accident. Never store
the inflatable spare tire or jack and tools in
the passenger compartment .
