Wheels and Tires
General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
~Have faulty tires or rims re­
placed immediately.
~Protect your tires from oil,
grease and fuel.
~Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
~Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(D Note
-Please note that summer and winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be
used in winter driving condi­
tions. The surface of the rims does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

Wheels
-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 noticeab le
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear more qu ickly .
Treadwear indicator
Original equipment t ires 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 ti re per­
pendicular to the running direc­
tion. The letters
"TWI" or trian ­
gles on the tire sidewall indicate
the location of the treadwear in­
dicators .
T he tires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones

wear evenly . To rotate the tires,
install the tires from the rear ax le
on the front axle and vice versa .
This will allow the tires to have app roximately the same lengt h of
service life .
F or unidirectional tires , make
sure the ti res are installed accord­
ing to the running direction indi­
cated on the tire sidewall

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 , drive slow ly and caref ully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
& WARNIN G ~
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.

cle.
.,.Check the tire sidewall
(¢ page 283, fig. 264) to deter­
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo­
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble
them £:=?.&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢page 314.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident .
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion on ice and snow.
298
.. Use winter tires on all four wheels .
.. Only use winter tires that are approved for your
vehicle.
.. Please note that the maximum permitted
speed may be lower with winter
tires¢ _&.. An
authorized Audi dealer or authorized Audi Serv ­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after installing wheels
¢page 293 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages , re­
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire 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 tires can lose traction on black ice .
® For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and 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. .,.

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
¢ page 128.
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

Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended fo r use in a specific direction, please note
the following:
- The direction of rotat ion is marked by an arrow
on the side of the tire .
- If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora ­
rily s ince the tire will not be able to achieve its
opt imum performance character istics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay particular atten­
t ion to this fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tiona l tire .
Notes on wheel changing
Please read the information ~ page 290 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb
(120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire ,
they should be replaced before you check the
tightening torque .
Emergency assistance
-Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.
Until then , drive with extra care and at reduced
speeds.
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read the information
Q page 290.
- Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
properly secured in the luggage compart­
ment and are not loose in the passenger
compartment.
- In an accident or sudde n maneuver they
could fly forward, injuri ng anyone in the ve­
h icle .
- Always store damaged wheel, jack and tools
securely in the luggage compartment. Oth­
erwise, in an accident or sudden maneuver
they could fly forward, causing injury to pas­
sengers in the vehicle.
