r im
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
ed periods of time. The ratings range from 93 mph (150 km/h)
to
186 mph (298 km/h) ¢ table

maximum permissible road
speeds. See
also ¢.& in General
information on page 201.
Tire pre ssure mon itoring
system *
means a system that detects
when one or more of a vehicle's
tires are underinflated and illumi­
nates a low tire pressure warning
telltale.
Tread
means that portion of a tire that
comes into contact with the road .
Tread separation
means pulling away of the tread
from the tire carcass.
Treadwea r indicators (TWI)
means the projections within the
principal grooves designed to give
a visual indication of the degrees
of wear of the tread. See
¢ page 210, Treadwear indicator
for more information on measur­
ing tire wear .
Uniform Tire Quality Grading
is a tire information system devel­
oped by the United States Nation­
al Highway Traffic Safety Admin­
istration (NHTSA) that is designed
to help buyers make relat ive com-
Wheels
parisons among tires . The U TQG
is not a safety rating and not a
guarantee that a tire will last for
a prescribed number of miles
(kilometers) or perform in acer­
tain way . It simply gives tire buy ­
ers additional information to
combine with other considera­
tions, such as price, brand loyalty and dealer recommendatio ns. Un­
der UTQG, tires are graded by the
tire manufacturers in three areas :
treadwear, traction, and tempera­
ture resistance. The UTQG infor­
mation on the tires, molded into
the sidewalls.
U.S. DOT Tire Identification
Number (TIN)
T his is the tire's "se ria l number" .
It begins with the letters "DO T"
and indicates that the tire meets
all federal standards. The next
two numbers or letters indicate
the plant whe re it was manufac­
tured, and the last four numbers
represent the week and year of
manufactu re . For example,
DOT .. . 2217 ...
means that the tire was produced
in the 22nd week of 2017 . The
other numbers are marketing co­ des that may or may not be used
.,.

Wheels
-Only use tires that are more than six years old when abso­lutely necessary and drive
carefully when doing so.
-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 al­low enough a ir 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.
l) Obey any applicable regulations in your
country.
210
-Driving qu ickly 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.
-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 quick ly.
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
c> fig . 186. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The t ires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
c> A . "'

Ti re rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the t ires,
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 i ng to the running direction indi­
cated on the tire sidewall
¢page 231.
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, dr ive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.

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
risk of hydroplaning when driv­
ing through deep puddles.

Wheels
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially
loaded ¢ table
on page 213 .
If driving the vehi­
cle when fully loaded, you must
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 . 188 for
the correct tire pressure based
on vehicle load.
~correct the tire pressure if nec­
essary .
~store the new tire pressure in
the Infotainment system
¢ page 220.
~check the pressure in the emer­
gency tire*/spare tire*. Always
maintain the maximum temper­
ature that is specified for the
tire.
212
& WARNING
Always adapt the tire 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 214,
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.
{tfj) Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.

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
increase the risk of the loss of
vehicle control.
- The brakes on a vehicle 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 blowout and
sudden deflation, causing loss
of control and a crash .
- Always make su re that the to­
tal load being transported - inc lud ing the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle We ight Rating.
Determining correct load
limit
~ Use the example below to calcu-
"' 8 late the total weight of the pas­s ..
Wheels
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed .
Steps for Determining Correct
Load Limit
1 . L ocate the statement "THE
COMB INED WEIGH T OF OCCU­
P ANTS AND CARGO S HOU LD
N EVER EXCEED XXX KG OR XXX
L BS " on your vehicle's placard
(tire inflation pressure label)
<=> page 211, fig. 187.
2. Determine the combined
weight of the driver 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 sticker
<=> page 211, fig . 187 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity . For ex ­
ample, if the "XXX" amount
equa ls 1400 lbs. and there will
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lbs.

Winter tires
Winter t ires signif icant ly imp rove the vehicle's
handling when dr iv ing in winter conditions. Be­
c au se of their construct io n (w id th, compou nd,
t read pa ttern), s ummer tires prov ide less t rac ­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. Only use winter tires that a re app roved fo r yo ur
veh icle .
.,. Please note that t he maximum permitted
speed may be lower with winter
tir es ¢ A in
G en eral information on pag e 201 .
An a uthor ­
i z ed Aud i dealer or authori zed Aud i Serv ice Fa­
cility can inform you about the maximum per­ m itted speed for your tires .
.,. Check the tire pressure after installing wheels
ca:;, page 211 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 i n (4 mm) . The characte rist ics of winter
t ir es also decrease g reatly as the t ire ages , re­
gard less of t he rema ining t read.
@ For the sake of the environment
Re insta ll summer t ires at the app ropr iate
time, bec ause they prov ide better handli ng
when ro ads are free of snow and ice. Summer
tires cause less roa d noise, tire wear and fue l
consumpt ion .
