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

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

formation is used to contact con

recall.
Vehicle capacity weight
means the rated cargo and lug

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. ,..

&,. 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
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

vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
The original tires on your vehicle
have 1/16 inch (1.6 mm) high
"wear indicators"¢
fig. 189 run
ning across the tread. Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear in
dicators .
The tires have reached the mini mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones ¢A.
Tire rotation
Rotating the tires regularly is rec
ommended to ensure the tires
wear evenly. To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord-
~ l) Obey any applicable regulations in your 0
§ country.

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.
A WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega
tive effect on handling, on the risk aquaplaning when driving
through water, when driving
through curves and when brak
ing, which increases the risk of
an accident.

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 labe l¢

¢ page 230 .
.,.Check the pressure in the emer

maintain the maximum temper
ature that is specified for the

A WARNING
Always adapt the t ire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe
ty precautions in ¢
page 223,
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
braking behavior, which in
creases the risk of an accident .
(D Note
Replace lost valve caps to re
duce the risk of damage to the
tire valves.
