rim flanges.
Sidewall
means that portion of a tire be­
tween the tread and bead.
Speed rating (letter code)
means the speed at which a tire is
designed to be driven for extend­

this information on all tires be­
cause it is not required by law.

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
ture resistance. The UTQG in for­

U.S. DOT Tire Identification
Number (TIN)
T his is the t ire's "serial number".
It begins w ith 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 ... 2214 ...
means that the tire was produced
in the 22nd week of 2014. The
other numbers are marketing co­
des that may or may not be used
2 5 6
by the tire manufacturer. T his in­
formation is used to contact con­
sumers if a tire defect requires a
recall.
Vehicle capacity weight
means the rated cargo and lug­
gage load plus 150 lbs (68 kg)
times the veh icle's designated
seating capacity.
Vehicle maximum load on the
tire
means that load on an individual
tire that is determined by distrib­
uting to each axle its share of the
maximum loaded vehic le weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual
tire that is determined by distrib­
uting to each axle its share of the
curb weight, accessory weight,
and normal occupant weight (dis­
tributed in accordance with¢ ta­
ble on page 262) and dividing by
two. ~

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 adhesion 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 Original equipment tires. If
you would like to use different
tires, please note that the tires

they are the same size¢,&..

tion that is different from what

The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily 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.
II WARNING -I
-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 6 years old when abso­
lutely necessary and drive
carefully
when doing so.
258
-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

tor
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.

ii ~
-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.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are
1/16 in (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion¢ fig. 193. The letters "TWI"
or triangles on the tire sidewall
indicate the location of the tread­
wea r indicators.
The tires have reached the mini ­
mum tread depth l) when they
have worn down to the tread wear
indicators. Replace the tires with
new ones ¢ .&.
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front ax le and vice
versa. This will allow the tires to
~ l) Obey any applicable regulations in your
:0 country . .....
Wheels
have approximately the same
length of service life.
F
or unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢ page 282.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are
hidden. Unusual vibrations in the
vehicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately.
Check
the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility
to have the vehicle inspect­
ed.
.&. WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.

tive effect on handling, on the

increase the tire pressure to the
maximum specified pressure¢.&..
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 Label¢ fig. 195 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 269.
•Check the pressure in the emer­
gency tire*/spare tire*. Always
maintain
the maximum temper­
ature that is specified for the
tire.
A WARNING

Always adapt the tire pressure
to your driving style and vehicle
load.

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

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.
The Gross Axle
Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
