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.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking 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
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.

Uniform Tire Quality Grading
is a tire information system devel ­
oped by the United States Nat ion­
a l Highway Traffic Safety Admin­
istration (N HTSA) that is designed
to he lp buyers make relative com-
33 6
parisons among tires . The UTQG
is not a safety rat ing and not a
guarantee that a tire will last for
a prescribed number of miles (kilo meters) or perform i n acer­
tain way . It simply g ives ti re buy ­
ers add itiona l information to
combine with other considera ­
tions, such as price, brand loyalty
and dealer recommendations. Un­
de r UT QG, tires a re graded by the

U.S. DOT Tire Identification
Number (TIN}
This is the tire's "serial number" .
It beg ins with the letters "DOT"
and indicates that the tire meets
all federal s tandards. The next
two numbers or le tters indicate
the plant whe re it was manufac ­
tured, and t he last four num bers
represent the week and year of
manufac ture. Fo r example,
DOT ... 2217 ...
means that the tire was produced
in the 22nd week of 2017. The
other num bers are ma rketing co­
des that may or may not be used

Wheels
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
ing to the running direction indi­
cated on the tire sidewall
¢ page 362.
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
s ide, 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.
This can increase the risk of an
accident because it has a nega­
tive effect on handling, driving
through curves, and braking, and because it increases the
340
risk of hydroplaning when driv­
ing through deep puddles.

A WARNING ,-= · -
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death .
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and i ncrease the risk of the loss of
vehicle control.
-The brakes on a veh icle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has been overloaded can fail sud­
denly, including a b lowout and
sudden deflation, causing loss
of contro l and a crash.
-Always make sure that the to­ tal load being transported -i nc luding the weight of a tra il­
er hitch and the tongue
weight of a loaded trailer­
does not make the vehicle
h eavier than the vehicle's
Gross Vehicle Weight Rating.

Determining correct load
limit
Use the example below to calcu­
late the tota l weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be over load ­
ed.
Steps for Determining Correct Load Limit
1 . Locate the statement " TH E
COMBIN ED WE IGH T OF OCC U­
PANTS AND CARGO SHOU LD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehic le's placard
(tire inflation pressure label)
¢ page 340, fig . 272 .
2. Determine the combined
weight of the drive r and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢
page 340, fig. 272 .
4. The resu lting figure equa ls the
available amount of cargo and
luggage load capacity . For ex­

Winter tires
Winter tires sign ifican tly imp rove the vehi cle's
handling when dr iv ing in winter conditions . B e­
ca use of their const ruct ion (w idth, compou nd,
tread pattern), summer tires provide less trac ­
tion on ice and snow .

tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking .
~ Only install snow chains on the front wheels.
~ Check and correct the seating of the snow
chains after driving a few feet, if necessary . Fol­
low the instructions from the manufacturer.
~ Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains . They must not add
more than 0 .53 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with ­
out snow. Otherwise, you could impair driving
ability and damage the tires.
.&_ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
(LlJ) Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them. Remove the wheel covers*
first. Use coated snow chains.
- Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be
very low. If
346
you drive with snow chains anyway, the
wheel housings and other vehicle compo­ nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch the offroad mode on
r=> page 143.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
Low -profile tires can become damaged more
quickly than standard tires when driving
over
large bumps, potholes, manhole covers, and
curbs . Therefore, it is particularly important to
maintain the correct tire pressure
r=.> page 340.
To reduce the risk of damage to the tires and
rims, drive
very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage . For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires .
