Uniform Tire Quality Grading
is a tire information system devel-
oped by the United States Nation-
al Highway Traffic Safety Adminis-
tration (NHTSA) that is designed
to help buyers make relative com-
250
parisons among tires. The UTQG is
not a safety rating and not a guar-
antee that a tire will last for a
prescribed number of miles (kilo-
meters) or perform ina certain
way. It simply gives tire buyers
additional information to com-
bine with other considerations,
such as price, brand loyalty and
dealer recommendations. Under
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)
This is the tire’s “serial number”.
It begins with the letters “DOT”
and indicates that the tire meets
all federal standards. The next
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... 2220...
means that the tire was produced
in the 22nd week of 2020. The
other numbers are marketing co-
des that may or may not beused >

by the tire manufacturer. This 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 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 vehicle 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 256) and dividing by
two.
Occupant loading and distri-
bution for vehicle normal load
for various designated seating
capacities
Refer to the tire inflation pressure
label > page 254, fig. 176 for the
number of seating positions. Re-
fer to the table > table on
page 256 for the number of peo-
ple that correspond to the vehicle
normal load.
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
optimal gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
> Only use tires with the same de-
sign, size (rolling circumfer-
ence), and as close to the same
tread pattern as possible on all
four wheels.
> Applies to: RS models: Only use
tires with the same design, size
(rolling circumference), and the
same tread pattern on all four
wheels.
>Do not replace tires individually.
At least replace both tires on the
same axle at the same time.

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 al-
low 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.

D Obey any applicable regulations in the
country where the vehicle is being oper-
ated.
—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.
—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 inch (1.6 mm) high and are
spaced evenly around the tire per-
pendicular to the running direc-
tion > fig. 174. The letters “TWI”
or triangles on the tire sidewall
indicate the location of the tread-
wear indicators.
The tires have reached the mini-
mum tread depth !) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones > A.
253

Wheels

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 according to
the running direction indicated on
the tire sidewall > page 279.
Hidden damage
Damage to tires and rims can of-
ten occur in locations that are hid-
den. Unusual vibrations in the ve-
hicle 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.


Z\ WARNING
Tread that has worn too low or
uneven tread depths on the
tires can reduce driving safety.

254

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.

Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded > table
on page 256. If driving the vehi-
cle when fully loaded, you must
increase the tire pressure to the
maximum specified pressure > A.
Checking and 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.
>Refer to the sticker > fig. 176
for the correct tire pressure.
>Correct the tire pressure if nec-
essary.
>Store the new tire pressure
> page 263 or » page 265.
> Check the pressure in the spare
tire (compact spare tire)*. Al-
ways maintain the maximum
temperature that is specified for
the tire.


—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 257.
—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 increas-
es tire wear and has a negative
effect on driving and braking
behavior, which increases the
risk of an accident.



/\ WARNING
Always adapt the tire pressure
to your driving style and the ve-
hicle load.

@) Note
Replace lost valve caps to re-
duce the risk of damage to the
tire valves.
© For the sake of the envi-
ronment
Tire pressure that is too low in-
creases fuel consumption.

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 Rating
(“GVWR”).

does not make the vehicle
heavier than the vehicle’s
Gross Vehicle Weight Rating.
Determining correct load
Talis
Use the example below to calcu-
late the total 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 overload-
ed.

Steps for Determining Correct
Load Limit
1. Locate the statement “THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS” on your vehicle’s placard
(tire inflation pressure label)
=> page 254, fig. 176.
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 254, fig. 176.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex-
ample, if the “XXX” amount
equals 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.
(1400-750 (5 x 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex-
ceed the available cargo and
luggage load capacity calculat-
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
>Check the tire sidewall
(= page 245, fig. 173) to deter-
mine the designated load rating
for a specific tire.
