General information
.,. Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled .
.,. Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D N ote
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons . Audi recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
2 10
and b raking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

comparisons among tires. The
UTQG is not a safety rating and not a guarantee that a tire will
last for a prescribed number of
miles (kilometers) or perform in a
certain way. It simply gives tire
buyers additional information to
combine with other considera ­
tions, such as price, brand loyalty
and dealer recommendations. Un ­
der UTQG, tires are graded by the
tire manufacturers in three areas:
treadwear, traction, and tempera ­

U.S. DOT Tire Identification
Number (TIN)
This is the tire's "serial number".
It begins with the letters "DOT"
and indicates that the tire meets
all federal standards. The nex t
two numbers or letters indicate
the plant where it was manufac­
tured, and the last four numbers represent the week and year of
manufacture. For example,
DOT ... 2216 ...
means that the tire was produced
in the 22nd wee k of 2016. The
other numbers are marketing co­
des that may or may not be used
2 16
by the t ire manufacturer . This in­
formation is used to contact con­
sumers if a tire defect requ ires a
recall.
Vehicle capacity weight
means the rated cargo and lug­
gage load pl us 150 lbs. (68 k ilo ­
grams) times the vehicle's desig­ na ted seating capacity .
Vehicle maximum load on the

uting to each axle its sha re of the
maximum loaded vehic le we ight

by two.
Vehicle normal load on the tire
means that load on an individual
tire that is determined by d istrib­
ut ing to each axle its share of the
curb weight, accessory weight,
and normal occupan t weight (dis­
tr ibuted in accordance with ¢
ta­
ble on page 222) and dividing by
two.

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.
Applies to: vehicles with all whee l dr ive
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
218
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

tor
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
