Uniform Tire Quality Grading
is a tire information system developed by the
United States National Highway Traffic Safety
Administration (NH TSA) that is designed to
help buyers make relative comparisons among
tires. The UTQG is not a safety rating and not a
guarantee that a tir e will last fo r a prescribed
number of miles or perform in a certain way.
It simply gives tire buyers additional informa­
tion to combine w ith other considerations,
such as price, brand loyalty and dea ler recom­
mendations. Under UTQG, tires are graded by
the tire manufacturers in three areas: tread­
wear, tract ion and temperature resistance.
The UTQG information on the tires, molded in­
to 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 a
ll federal standards. The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example,
DOT . .. 2210 ...
means that the tire was produced in the 22nd
week of 2010. The other numbers are market­
ing codes that may or may not be used by the
tire manufacturer . This information is used to
contact consumers if a tire defect requires a
recall.
Vehicle capacity weight
means the rated cargo and luggage load plus
150 lbs. (68 kilograms) times the vehicle's to­
ta l seating capacity as listed on the label lo­

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 150 Tire pressure label: located on driver's side B·
pillar
Tire pressure generally refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals (kPa), the interna­
tional measuring unit and in pounds per
square inch (PSI). Tire pressure is based in
part on the vehicle's design and load limit­
the greatest amount of weight that the vehi­
cle can carry safely and the tire size. The prop­
er tire pressure is frequently referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "cold." It is the
inflation pressure in a "cold" tire that counts.
Therefore, you should never let air out of a
warm tire to match "cold tire inflation pres­
sure" recommendations. The tires would then be underinflated and could fail suddenly.
Maintaining proper tire pressure is one of the
most important things you can do to help
avoid sudden tire failure. Underinflated tires
are a major cause of sudden tire failure. Keep­
ing tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,
traction, braking and load carrying .
Tire pres­
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­
ties approved for your vehicle.

INFOl n
u
The recommended tire pressures for your Audi
depend on the kind of tires on your vehicle
and the number of passe ngers and/or amount
of luggage you will be transporting.
The tire pressure label located on driver's side
B-pillar on your Audi lists the recommended
cold tire inflation pressures for the vehicle at
its maximum capacity weight and tires that
were on your vehicle at the time it was manu­
factured.
If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 2 occu­
pants), you can adjust tire pressures to those
specified for normal vehicle load. Before oper­
ating the vehicle at maximum load, you must
increase the tire pressures to those specified
for maximum vehicle load
9 .&.
Bear in mind that the tire pressure monitoring
system can only monitor the tire pressures
that are stored. The system does not recog­
nize the load condition of your vehicle.
See the illustration,:;,
fig. 150 for the location
of the label on driver's side B-pillar (color of
the actual label and exact location on the ve­
hicle will vary slightly).
Note that the following table is accurate at
the time of going to press and is subject to
change. In the event of discrepancies, the tire
pressure label on driver's side B-pillar always
ta kes precedence. ..,.

Because tec hnical changes may be made to
vehicle equ ipment dur ing the model yea r, a l­
ways compare the tire size designation on the
tire pressure labe l on you r vehi cle w it h the
tires on your vehicle. Make s ure that the ti re
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
load limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
veh icle . These load lim its are technically refer­
red to as the vehicle's G ross Vehicle We ight
Rati ng ("GVWR"). The G ross Ax le Weight Rat­
i ng ("GAWR") is the max imum load that can
be app lied at each o f the veh icle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance stic ker labe l located either
on the driver's side B-pillar. The tire pressure
labe l on your Audi lists the maximum com­
b ined weight of all of the occupants and lug­
gage or other cargo that the veh icle can carry.

.&_ WARNING
Overloading a vehicle can cause loss of ve­
h icle cont ro l, a crash o r other accident, se ­
r ious pe rsonal injury, and even death.
- Ca rrying more we igh t than your veh icle
was designed to carry wi ll prevent the
vehicle from handling properly and in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been over load­
ed can fail s uddenly ca us ing loss of con­
trol and a crash.
.&_ WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
f lation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and sudden de­
flation, ca using loss of veh icle cont ro l.

196 Tires and wheels
wheels you have to adjust the tire pressures
on all wheels.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin­ flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle .
The applicable pressure values are locat­
ed on a sticker on the driver's side 8-pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system can work cor­
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor­
ing system .
- Always inflate tires to the recommended
and correct tire pressure before driving
off .
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the tires will wear prematurely and the
vehicle will not handle well. -
If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the tire pressure and add
air as required .
(D Note
Driving without valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also increase the
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 also damage important parts of the
vehicle and can lead to sudden tire failure, in­ cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle . These
load limits are technically referred to as the
vehicle 's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs. (68 kg) for each
passenger at a designated seating position
and the total weight of any luggage in the ve-
hicle. ..,_

The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-pi llar . Your Audi has 2 seat ing
positions in the front for total seat ing capac i­
t y of 2. Each seating posi tion has a safety belt
c::> page 109, Safety belts.
The fact that there is an upper limit to your
ve hicle's Gross Veh icle Weight Rating means
that the total weight of whatever is being car­
ried in the veh icle is limited . The more passen­
gers in the veh icle or passengers who a re
heavier than the standard weights assumed
mean that less weight can be carried as lug­
gage.
The t ire pressure label on your Audi also lists
the maximum combined we ight of all of the
occupants and luggage o r othe r cargo that
the vehicle can carry. For the location of the
la be l
c::>page 193, fig. 150.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
r ious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of veh icle con­
trol.
- 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 overload­
ed can fail suddenly, includ ing a b lowout
and sudden deflation, causing loss of
control and a crash.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
Tires and wheels 197
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX
KG OR XXX LBS"on your vehi­
cle's placard (tire inflation
pressure label)
¢ page 193,
fig. 150.
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 pas­
sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 193, fig. 150.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci-
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs. passengers in your vehi­
c le, the amount of available .,..

198 Tires and wheels
cargo and lugg age load ca­
pacity is 650 lb s. (1400-750
(5
X 150) = 650 lb s.)
5. Determin e the combined
weight of luggage and cargo
being loaded on the vehicle .
That weight may not safely exceed the a vailable cargo
and luggage load capacity
c alculated in Step

6. If your vehicle will be towing
a trailer , load from your trail­
er w ill be tran sferred to your
vehi cle . Consult this manual
to determine how thi s re­
duces the available cargo
and luggage load capacity of
your vehicle.

Driving style
Driving fast around c urves, heavy accele rat ion
and hard braking increase tire wear .
Wheel balancing
The wheels on new ve hicles are balance d.
However, va rious s ituations dur ing everyday
driv ing can cause them to become unbal·
anced, resulting in vib rations you can usually
