would then be underinflated a nd
could fail suddenly .
M ainta ining proper tire pressure
is one of the most important
things you can do to he lp avoid
s u dden tire fai lure . Under inflated
tires are a major cause of sudden
tire fa ilure . Keeping tires at the
r ight pressure is also important
for safe and responsive vehic le
handling, traction, braking and
load carrying.
Tire pressures are
particularly important when the
vehicle is be ing dr iven at higher
speeds, and then especially when
heavily loaded even within the
permissib le load-carrying capaci­
ties approved for your vehicle .
The recommended tire pressures
for your Audi depend on the kind of tires on your vehicle and the
number of passengers and/or
amount of luggage you will be
transport ing .
The tire pressure label is located
on the driver's side 8-pillar . The
tire pressure label lists the recom­ mended cold tire inflation pres­
s u res for the vehicle at its maxi­
mum capacity weight and tires
~ that were on your vehicle at the
": ;;; time it was manufactured. "? N

Tir es a nd whe els
If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occupants ),
you can adjust tire pressu res to
those specified for normal vehi­
cle load . Before operating the ve­
hicle at ma ximum load, you
must increa se the ti re pressures
to those specified for maximum
vehic le load
c:::> .&. .
Bear in mind that the tire pres­
sure monitoring system can only monitor the tire pressures that
are stored. The system does not recognize the load condition of
your vehicle .
See the illustration

the location of the labe l on driv­
er's side 8-pillar (color of the ac­
tual label and exact location on
the vehicle will vary slightly).
Note that the following table is
accurate a t the time of going to
press and is subject to change . In
the event of discrepancies, the
tire pressure label on driver's side 8-pillar always takes precedence.

Tires and wheels
-Temperature grades apply to tires that are properly inflated and not over or underinflated.
-For technical reasons it is not always possible to use wheels
from other vehicles -in some
cases not even wheels from
the same vehicle model.
-Do not use run-flat tires on your vehicle. Using run-flat
tires can lead to vehicle dam­age or crashes.
(D Note
-For technical reasons, it is not generally possible to use the
wheel rims from other
vehicles. This can hold true for
wheels of the same vehicle
type.
-If you should put different wheels and tires on your vehi­
cle (e.g. winter wheels and
tires), you must be certain
that the wheels and tires are compatible with the tire pres­
sure monitoring system. Oth­
erwise the system will register
a malfunction and a fault message will be displayed. For
more information, contact
your authorized Audi dealer.

(D Note
-When installing new tires, be careful not to damage the
valves or tire pressure moni­
toring system sensors.
-Never drive without the valve stem cap. The valves could get
damaged.
-If the sensors must be re­ placed, then the valve must
also be replaced at the same
time.
@) For the sake of the environment
Dispose of old tires in accord­
ance with the local require­
ments.
(D Tips
Tires with the identification "ROl" have been specially matched with your Audi. We
recommend using only these
tires because they meet the highest standards regarding
safety and driving characteris­
tics when used correctly. Your authorized Audi RB dealer will
gladly provide you with more information.

CD Note
-Remove snow chains before driving on roads
not covered with snow to avoid damaging
tires and wearing the snow chains down un­ necessarily.
- Snow chains, which come into direct contact
with the wheel rim, can scratch or damage
it. Therefore, make sure that the snow
chains are suitably covered . Check the posi­
tion of the snow chains after driving a few
yards and correct if necessary. Follow the in­
structions from the snow chain manufactur­
er when doing so.
(j) Tips
Where snow chains are mandatory on certain
roads, this normally also applies to vehicles
with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the fac­
tory installed rims. If different rims are fitted,
the correct wheel bolts with the right length and
correctly shaped bolt heads must be used. This
ensures that wheels are fitted securely and that
the brake system functions correctly.
In certain circumstances, you may not use wheel
bolts from a different vehicle -even if it is the
same model ¢
page 217.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of con­
trol, a collision and serious personal injury.
-
- Always keep the wheel bolts and the threads
in the wheel hubs clean so the wheel bolts
can turn easily and be properly tightened.
- Never grease or oil the wheel bolts and the
threads in the wheel hubs. They can become
loose while driving if greased or oiled, even
if tightened to the specified torque.
- Only use wheel bolts that belong to the rim
being installed.
Tires and wheels
- Never use different wheels bolts on your ve­
hicle.
- Always maintain the correct tightening tor­
que for the wheel bolts to reduce the risk of
a wheel loss. If the tightening torque of the
wheel bolts is too low, they can loosen and
come out when the vehicle is moving. If the
tightening torque is too high, the wheel bolts and threads can be damaged and the
wheel can become loose.
CD Note
The specified torque for the wheel bolts is 90
ft lb (120 Nm) with a tolerance of± 7 .4 ft lb
(± 10 Nm) . Torque wheel bolts diagonally. Af­
ter changing a wheel, the torque must be
checked as soon as possible with a torque
wrench -preferably by an authorized Audi
dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra­
tio tires. These tires have been thoroughly tested
and been selected specifically for your model for
their superb performance, road feel and handling under a variety of driving conditions . Ask your au­
thorized Audi dealer for more details.
The low aspect ratio of these tires is indicated by
a numeral of
55 or less in the tire's size designa­
tion. The numeral represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Conventional tires have
a height/width ratio of 60 or more.
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should be checked at least once a month and always
before a long trip

pressure.
