New tires or wheels
Audi recommends having all work
on t ires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace­
ment parts.
... New t ires do not yet have the
optim um gripping properties.
Drive carefully and at moderate
speeds for the first 35 0 m iles
(500 km) with new tires .
... Only use tires with the same de­
sign, size ( rolling circumfer ­
ence) , and as close to t he same
tread pattern as possible on a ll
four wheels .
...
Do not replace tires individually.
At least replace bo th tires on the
same axle at the same time .

like to use di fferent tires, please

vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase¢ ,&..
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel drive : all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­ aged by different wheel speeds.
For this reason, in case of emer­
gency, only use a spare tire* that
is the same circumference as the
regular tires .
Wheels
A WARNING
-Do not use steel rims that are
17 inches or larger. Other­
wise, damage to the vehicle and an accident could result.
-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.

Wheels
-Only use tires that are more than six years old when abso­lutely 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 al­low enough a ir circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage
Fig. 186 Tire profile: trea dwear indica ­
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
l) Obey any applicable regulations in your
country.
210
-Driving qu ickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quick ly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion
c> fig . 186. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The t ires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
c> A . "'

Ti re rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the t ires,
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 i ng to the running direction indi­
cated on the tire sidewall
¢page 231.
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, dr ive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.

This can increase the risk of an accident because it has a nega­
tive effect on handling, driving

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

Tread wear
The tread wear grade is a comparat ive rat ing
based on the wear rate of the t ire when tested
unde r contro ll ed conditions o n a specified gov ­

For example, a tire graded 150 would wear one

ment course as a tire g raded 1 00.
The relative performance of t ires depends upon
