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

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 kilo ­
grams) times the vehicle's desig­ nated 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 ­

New tires or wheels
Audi recommends having all work
on t ires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace­
ment parts.
... New t ires do not yet have the
optim um gripping properties.
Drive carefully and at moderate
speeds for the first 35 0 m iles
(500 km) with new tires .
... Only use tires with the same de­
sign, size ( rolling circumfer ­
ence) , and as close to t he same
tread pattern as possible on a ll
four wheels .
...
Do not replace tires individually.
At least replace bo th tires on the
same axle at the same time .
... Audi recommends that you use
Audi O riginal Tires. If you would
like to use di fferent tires, please
note that the tires may perform
...

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

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

or triangles on the tire sidewall indicate the location of the tread­
wear indicators.

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 in and on
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-
214
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar.

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.

Tread wear
The tread wear grade is a comparat ive rat ing
based on the wear rate of the t ire when tested
unde r contro ll ed conditions o n a specified gov ­

For example, a tire graded 150 would wear one
and one ha lf ( 11/2) t imes as well on the gove rn­
ment course as a tire g raded 1 00.
The relative performance of t ires depends upon
the actual condi tions of their use, howeve r, and
may depart s ignificant ly from the norm d ue to
va ria tions in driving hab its, service pra ctices and
d ifferences in road ch aract eris tics and clim ate.
