New tires or wheels
Audi recommends having all work on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­ ment parts.
... New ti res do not yet have the
optimum gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
... Use ti res of the same construc ­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
11> D0 not replace tires individually .
At least replace both tires on the
same axle at the same time .

11> Audi recommends that you use
Audi Original Tires . If you would
like to use different tires, please
note that the tires may perform
differently even if they are the
same size

.. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con ­

dealer or authorized Audi Service Facility before making a pur ­
chase
c:::> A .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
so only use the spare tire* tempo­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
On
a ll w heel drive vehicles, all
four wheels must be equipped
with t ires that are the same brand
and have the same construction
and tread pattern so that the drive system is not damaged by
different tire speeds. For this rea­
son, in case of emergency, only use a spare tire* that is the same .,.

tires.
A_ WARNING -
-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.
- Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
254
-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 al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Hav e an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if

-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 quickly.
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¢
fig. 189. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the tread wear
indicators. Replace the tires with
new ones ¢.&.
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have

service life.
For unidirectional tires, make
sure the tires 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 slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­ cility to have the vehicle inspect­
ed.
.&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving

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. 191 for
the correct tire pressure based
on vehicle load.
•Correct the tire pressure if nec ­
essary .
•Vehicles with Tire Pressure Mon­
itoring System*: store the modi­
fied tire pressure in the Infotain­ ment system ¢

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A 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.

Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci-
ty") with an assumed weight of ..,

a, a, ... N
" N ... 0
" V, a:,
150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle .
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle is limited.
The more passengers in the vehi­
cle or passengers who are heavier
than the standard weights as­
sumed mean that less weight can
be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side 8-pillar
¢ page 256,
fig. 190.
&_ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carry ing more weight than
your vehicle was designed to
carry will prevent the vehicle
Wheels
from handling properly and
increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-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
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 .,.
259

Wheels
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 256, fig. 190.
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
¢ page 256, fig. 190.
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-
260
hicle. Consult this manual to
determine how this reduces
the available cargo and lug­
gage load capacity of your vehi­
cle.
~check the tire sidewall
(¢ page 246, fig. 188) 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
¢ &..
_8. 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 2 78, Finishing.
- 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 .
