Wheels
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially
loaded ¢ table
on page 213 .
If driving the vehi
cle when fully loaded, you must
increase the tire pressure to the
maximum specified
pressure ¢.&. -
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 label¢ fig . 188 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 220.
~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 safe
ty precautions
in¢ page 214,
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.
{tfj) 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.

(D Tips
You can also use all season tires instead of
winter tires . Please note that in some coun
tries where winter tires are required, only
winter tires with
the ~ symbol may be per
mitted.
Snow chains
Snow chains not only improve the driving in win
ter road conditions, but also the braking .
.. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.. Check and correct the seating of the snow
chains after dr iv in g a few feet, if necessary . Fol
low the instructions from the manufacturer .
.. Note the maximum speed of 30 mph (SO km/
h). Note the loca l regulations.
Use of snow chains is only perm itted with certain
rim/tire combinations due to technical reasons.
Check with an authorized 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 .
{[J) 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 air suspension*, be
cause the vehicle height will be very low. If
Wheels
you drive with snow chains anyway, the
wheel housings and other vehicle compo
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch on sport
mode¢ page 120.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style . However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi
tion.
Low -profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers , and
curbs . Therefore, it is particularly important to
maintain the correct tir e pressure
¢ page 211.
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 authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand
ard tires .
Uniform tire quality grading
-Tread wear
- Traction AA ABC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
