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 tires 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 tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread pattern as possible on all four
wheels.
... use tires of the same construc­
tion, size (rolling circumference)
and the same tread pattern on
all four wheels.
... Do not replace tires individually.
At least replace both tires on the
same axle at the same time .
218
.,.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
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase¢
& -
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.
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 damaged by
different tire speeds . For this rea­
son, in case of emergency, only
use a spare tire* that is the same ...

8,_ 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.
Wheels
-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/damage

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. ..

and follow the important safe­
ty precautions in
q page 224,
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

(D Note
Replace lost valve caps to re­

@ For the sake of the environment
Tire pressure that is too low in­

(D Tips
Audi recommends using the
tire pressure specified for a
normal load

or for a full load
when the vehicle is partially
loaded.
Make sure that the tire designa­
tion on your tire matches the des­
ignation on the tire pressure label

mended tire pressures in cold

Low aspect ratio tires
Your Aud i is f actory-equipped wi th low aspec t ra­
t io tires. The se tir es h ave bee n thor oughly te sted
and b een se lected s pecific ally fo r yo ur model fo r
their superb perfo rmance , road feel and hand ling
un der a va riety of driving conditions. As k yo ur au ­
thor ized Audi dealer for mo re details .
Th e low aspect ratio of these tires is indi cate d by
a nume ra l of
55 or less in t he tire's size desig na­
tion. The nume ra l r ep resents the rat io of t he
tire's sidewall he ight i n relat ion to its tread wi dth
expressed in pe rcentage. Conventional tires have
a heig ht/w idt h rat io o f 60 o r mo re.
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~
page 221.
228
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
l y by impact with potho les, curbs, gullies or
r idges on the road, particularly if the tire is un ­
der inflated.
In orde r to mi nimize the occurrence of impact
damage to the tires o f yo ur vehicle, we recom ­
mend that you observe the following preca u­
tions:
- Always maintain recommended inflation pres ­
sures. Check yo ur tire pressure every 2,000
m iles (3,000 km) and add a ir if necessary.
- Dr ive carefully on roa ds w it h potholes, deep
gullies o r ridges. The impact from dr iv ing
throug h or over such obstacles can damage
your t ires. Impac t with a curb may a lso ca use
damage to yo ur tir es.
- After a ny impact, immed iate ly inspect you r
tires or have them inspected by the nearest au ­
t horize d Aud i dealer . Replace a damage d tire as
soo n as poss ible .
- Inspec t your tir es ev ery 2,000 m iles (3,000 km)
for d amage and wear . Damage is no t always
easy to see . Da mage ca n lead to loss o f air and
un derinfla tion, w hich could eve ntually ca use
t ire f ailure. If yo u be lieve th at a tir e m ay h ave
been dam age d, rep la ce the tire as soon as pos ­
sible .
- These tire s may wea r mo re quick ly th an ot hers.
- Ple ase also remember th at , while t hese tires

system
ill General notes
Each tire, including the spare (if provided),
shou ld be checked monthly whe n cold and inflat­
ed to the i nflat io n press ure recommended by the
vehicle manufacturer on the veh icle placard or
t ir e inflation pressure labe l. (If your ve hicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determ ine the proper tire infla­
t ion pressure for those tires).
As an added safety feature, yo ur vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire pressure tell­
ta le when one or more of your tires is signif icant­
ly under-inflated. According ly, when the low t ire
pressure te lltale illum inates, you sho uld stop and
chec k your tires as soon as possib le, and inflate
t h em to the prope r pressure. Dr iving on a sig nifi­
ca nt ly unde r-inflated t ire causes the t ire to over ­
hea t and can lead to tire fa il ur e. Under-inflat ion
also reduces fue l effic iency and tire tread life,
and may affect the vehicle's handling and stop -
ping ability .
