New tires or wheels
Audi recommends having all work on tires or wheels performed by
an author ized 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.
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
Wheels
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.
On
all wheel drive vehicles, 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
circumference as the regular
tires. .,.

Wheels
&,. 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.
-Do not use run-flat tires on
your vehicle. Using them when
238
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­low 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.
-Dr iving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty chec k the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable

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

Tire pressure that is too low in­ creases fuel consumption.

A WARNING
Using incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i­
dent .
(D Note
Snow chains can damage the rims/wheel cov ­
ers * if the chains come into d irect contact
w ith them. Remove the wheel covers* first .
Use coated snow chains.

When using snow cha ins, it may be useful to

Low aspect ratio tires
Your Audi is factory -equipped with low aspect ra­
tio tires. These t ires have been tho roughly tested
a nd been se lected specifically fo r yo ur model fo r
thei r supe rb per fo rman ce , road feel and handling
un der a va riety of d riving conditions . As k yo ur au­
thor ized Audi dealer for mo re details .
T he low aspect ratio of these t ires is in dicated by
a nume ral of
55 or less in the tire's size desig na­
tion . The numera l rep resents the rat io o f th e
tire's sidewall he ight in relat ion to its tread width
expressed in pe rcentage. Conventional tires have
a height/w idt h rat io o f 60 o r more .
The performance of low-aspect -ra tio tires i s 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 240.
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, cu rbs, gullies or
246
ridges on the road, particularly if the tire is un ­
derinflated.
I n orde r to mi nimize the occur rence o f imp act
dam age to the tires o f yo ur vehicle, we recom­
mend that you observe the following preca u­
tions:
- Always m aintain reco mmende d in fla tion pres­
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,00 0 km) and add air if necessary .
- Dr ive c arefully on ro ads w ith potholes, deep
gu llies o r ridges . The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your t ires.
- After any impact, immediate 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.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
unde rinflation, w hich could event ua lly cause
tire fa ilure . If you believe that a tire may have
be en damaged, replace the tire as soon as pos­
sible .
- These tires may wear mo re quickly than o thers .
- Please also remember that, while these tires delive r responsive hand ling, they may ride less
comfortab ly and make mo re noise than o ther
choi ces.
Reduced performance in winter/cold season
conditions
A ll tires are des igned for certain purposes. The
l ow aspect ratio, ultra h igh performance tires
o rigin ally ins talle d on your veh icle are inten ded
for m aximum dry and wet road per forma nce and
handling . They a re not suitable for co ld, snowy or
i cy weather conditions . If you drive under those
c ir cumstances, you should equip yo ur vehicle
with all-season o r winter tires, which offer better
tract ion under t hose conditions. We suggest you
u se the recommended s now or all-season tires
spec ified for your vehicle, o r the ir equiva lent .

Q ua lity grades ca n be found where ap plicable on
the tire side wall between tread shoulder and

For example: Tread wear 200 , Traction AA, Tem­
perature
A .
All passenge r ca r tires m ust conform to Federal
Safety Requirements in add ition to these grades .
Tread wear
The tread wear grade is a comparat ive rating
based on the wear rate of the t ire when tested
under cont ro lled conditions o n a specified gov ­
e rnment test course.
For example, a t ire graded
1 50 would wear one
and one ha lf
( 1 1/2) times as well on the gove rn­
men t course as a tire g raded
100.
The relative performance of t ires depends upo n
the actual conditions of their use, howeve r, and
may depart significant ly from the norm due to
va ria tions in driving ha bits, serv ice practices and
d ifferences in road cha racteristics and climate .
Traction
The traction grades, from highest to lowest, are
AA, A, B and
C. T hose grades represent the t ire's
ab il ity to stop on wet pavement as meas ured un ­
de r contro lled condi tions on specified gove rn­

Temperature
The temperature grades are A (t he hi ghest), B ,
