-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 6 years old when abso
lutely 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 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.
-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 quickly.

The correct tire pressure for tires
installed at the factory is listed on
a label. The label is located on the B-pillar
¢fig. 192, ¢fig. 193.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded¢
table
on page 230 .
If driving the vehi
cle when fully loaded, you must increase the tire pressure to the
maximum specified pressure¢.&-
228
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 labe l¢
fig. 193 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 ¢
page 23 7.
A 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 230,
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 .
(D 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

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 150 lbs. (68 kg) for each passen
ger at a designated seating posi
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer hitch and the tongue weight of
the loaded trailer must be includ ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
Wheels
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢page 228, fig. 192.
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 228, fig. 192.
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
232
will be transferred to your ve
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 218, fig. 190) 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
9 &. .
_&. 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, refer to
9 page 244, After changing a
wheel .
-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.

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
tio tires. These tires have been thoroughly tested
and been selected specifically for your model fo r
thei r supe rb perfo rmance, road feel and handling
unde r a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re de tails.
The low aspect ratio of these t ires is indicated by
a nume ra l of
55 or less in the tire's size desig na
tion . The nume ra l rep resents the rat io of t he
tire 's sidewall he igh t in relat io n t o it s tread w idth
e xpresse d in percen tage. Convention al ti res have
a height/w idth ratio o f 60 o r more .
The performance of low -aspect-ratio tires is par
ticularly sensitive to improper inflation pres
sure. It is therefore important that low a spect
ratio tires are inflated to the specified pre ssure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
be checked at le ast once a month and alwa ys
before a long trip¢
page 228.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, curbs, gullies or
ridges on the road, pa rt icu la rly if the t ire is un
de rinflated.
In order to minimize the occurrence of impact
damage to the t ires of your ve hicle, we recom
mend that you observe the fo llow ing precau
tions:
- Always maintain recommended inflation pres
su res . Check your tire pressure every 2,000
miles (3,000 km) and add air if necessary .
- Drive caref ully on roads with potho les, deep
gul lies or r idges . The impact from drivi ng
through or over s uch obstacles can damage
you r tires. Im pact with a cu rb may also cause
damage to you r tires .
234
-After any impact, immed iate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire as
soon as possible.
- Ins pect your tires every 2,000 mi les (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
underinfla tion, w hich could even tua lly cause
tire fa ilure . If yo u be lieve that a tire may have
been damaged, replace the tire as soon as pos
sible.
- These tires may wear mo re quickly than others .
- Please also remember that, while t hese tires
delive r responsive hand ling, they may ride less
comforta bly and make mo re noise than o ther
choi ces.
