U ni form Tire Q ua lity G rading
is a tire information system developed by the United States Nationa l
Highway Traffic Safety Administration (N HTSA) that is designed to
help buyers make re lative comparisons among tires. The UTQG is
not a safety rating and not a guarantee that a tire will last for a
prescribed number of miles or perform in a certain way. It simply
gives tire buyers additiona l information to combine with other
considerations, such as price, brand loya lty and dealer recommen- dations
. Under UTQG, tires are graded by the tire manufacturers in
three areas : treadwea r, trac tion and temperature resistance. The
U TQG information on the tires, molded into the sidewalls.
U .S . DOT Tire Identifi cation Number (TIN )
This is the tire's "serial number" It begins with the letters "DOT" and
indicates that the ti re meets a ll federa l standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four num bers represent the week a nd year of manufac ­
ture. For example,
DOT ... 2209 ...
means that the tire was produced in the 22nd week of 2009. The
other numbers are marketing codes that may or may not be used by
t he tire manufacturer. This information is used to contact
consumers if a tire defect requires a recall.
Vehicle capa cit y weight
means the rated cargo and luggage load plus 150 lbs. (68 kilograms)
times the vehicle's tota l seating capacity as l is ted on the label
located either on the driver's side 8-pillar or on the inside of the fuel
f iller flap .
Vehicle maximum lo ad 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 dividi ng by two .
Vehi cle normal load on t he tire
means that load on an individual tire that is determined by d istr ib ­
uting to each axle its share of the curb weight, accessory weight,
and normal occupant weig ht (distribute d in acc orda nce with table
below=>
page 246) and dividing by two. .,

The correct t ire pressure for the
spare wheel is located on a label
either on the driver's side B-pillar or inside the fue l filler flap.
Because technica l changes may be made to vehicle equipment
during the mode l year, always compare the tire size designat ion on
the tire pressure la bel on y our vehicle with the tires on your vehicle.
Make sure tha t the t ire size information on the veh icle labe l is the
same as the size of the tires on the vehicle. This is especially impor ­
t ant if the vehicle belongs to someone e lse or you boug ht the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers a lso depends
on making su re tha t load limits a re not exceeded . Vehicle load
inc ludes 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 Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two
ax les. The Gross Vehicle We ight Rat ing and the Gross Ax le Weight
Rating are listed on the safety comp liance sticker labe l located
e it he r on the d river's side B-pillar o r on the i nside of the fuel f iller
flap. The tire pressure label on your Audi lists the maximum
combined we igh t of all o f th e occupa nts and luggage o r other cargo t
hat the vehic le can carry. For the location o f the tire pressure labe l
=> page 246, fig. 173.
& WARNING
Overloading a vehi cle can cause los s of vehicle control , a crash or
other accident, serious per sonal injury, and even death .
• Carrying more weight th an your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the
risk of a 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 c an fail suddenly
cau sing loss of control and a crash .
• Alway s make sur e that the total load being tran sported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle 's Gross Vehicle Weight Rating . _.,

& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
serious or fatal accident.
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side 8-pillar or inside the fuel filler flap.
The recommended tire pressures are on the tire pressure label and
in the table=> page
246, "Cold tire inflation pressure ". This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as 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
pressure" recommendations=>
page 246. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures for the new, original equipment tires that were
on your vehicle at the time it was manufactured. For the location of
the label =>
page 246, fig. 173.
Most tires lose air naturally over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not possible to see whether the radial tires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long." See=>
page 250, "Tires and vehicle load limits" for more
important information .
Always use an accurate tire pressure gauge when checking and adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire. If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you plan to do .
If the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer ,
determines the correct tire pressure for the tires on your vehicle.
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label. On
USA vehicles, the tire pressure label is located on driver's side B ­
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side B -pillar or inside the fuel filler flap.
• Turn the valve stem cap counter-clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve. ..,.
Vehicle care I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
• The tire pressures should only be checked and adjusted when
t he tires are cold . The s lig htly raised pressures of warm tires must
not be reduced .
• Adjust the ti re pressure to t he loa d you are carrying.
• Reinstal l the valve stem cap on the valve.
When should I c heck the tire pressure?
The correct ti re p re ssure is especially impo rtant at h ig h speeds . The
pressure should the re fore be checked a t le ast once a month and
a lways before starting a journey. Do not forget to check the tire pres ­
sure for the spare whee l
::::> page 269.
When should
I adjust the tire pressure s?
Adjust the tire pressure to the load you are carrying. A fter chang ing
a wheel
or r eplac ing whee ls you have to adjus t th e tire pre ssures on
a ll whee ls. In addit io n, you must the n initia lize the new t ire pres ­
sures in the tire pressure monitoring system* =>
page 263.
& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, los s of control, colli sion , serious personal injury or even
death .
• When the warning symbol appears in the instrument
c luster , stop and inspect the tire s.
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect tire pressures and /or underinfla tion can also lead to
sudden tire failure , including a blowout and sudden deflation ,
causing loss of vehicle control .
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticke r on the driver 's side B -pillar o r on the inside of the fuel
filler flap.
& WARNING (continued )
• Only when all tires on the vehicle are filled to the correct pre s­
sure , the tire pres sure monitoring sy stem * can work correctly.
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is e ssential that the driver observe
the specified tire pressure v alue s for the tires and the correct pres­
sures for the function of the tire pre ssure monitoring system* .
• Always inflate tires to the recommended and correct tire pres ­
s ure before driving off.
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation , sudden tire fa ilure 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 station
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
va lves. To prevent this, always make sure that fac tory ins talled va lve
stem caps on all whee ls are securely mounted on the valve.
Underinflated tires wi ll also increase the fuel consumption. •
Tires and vehicle load limits

and is more difficult to stop. Overloading can not only lead to loss
of ve hicle control, but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, inc luding a blowout and
sudden deflation that can cause the vehic le to crash.
Your safety and that of your passengers also depends on making
sure that load limits are not exceeded. Vehicle load includes every ­
body and everything in and on the veh icle . These load limits are
technically referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"l.
The "GVWR" includes the weight of the basic vehicle, al l factory
insta lled 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 vehicle. If you tow a trailer, the weight of the trailer hitch and the
tongue weight of the loaded trai ler must be included as part of the
vehicle load .
The
Gross Axle Weight Rating ("GAWR") is the maximum load that
can be applied at each of the vehic le's two axles .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compliance sticker label located either on
the driver's side B-pillar or on the inside of the fuel filler flap. Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Each seating position has a safety belt
=> page 135, "Safety belts".
The fact that there is an upper limit to your vehicle's Gross Vehicle
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 passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage .
T he tire pressure label on your Audi also lists the maximum
combined weight of all of the occupants and luggage or other cargo that the vehicle can carry.
For the location of the label
=> page 246,
fig. 173.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal 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 suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and
luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.

Incorrect wheel alignment
Incorrect wheel alignment can cause excess ive tire wea r, im pairing
the safety of the vehic le. If tires show excessive wear, have the
whee l alignment c hecked by an au th o rize d Audi deale r or qualifie d
wo rkshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size, c ons truc tion and tread type. F or details see ~ page
19 4.
& WARNING
Sudden tire failure can lead to los s of control, a crash and serious
personal injury !
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control .
• Always keep chemicals that can cause tire dam age , such as
grease, oil , gasoline and brake fluid aw ay from tires .
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and los s of veh icle control. •

& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always use tires , rims and wheel bolts that meet the specifica ­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
& WARNING (continued )
• All four wheels must be fitted with radial tires of the same type,
size {rolling circumference ) and the same tread pattern. Driving
with different tires reduces vehicle handling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build-up , sudden tire failure ,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated.
• For technical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels , make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory . The vehicle must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
system* that indicates a loss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels . Mi xing tire types is not permitted. _,.

Safety Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law.
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinfla­
tion , or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive*, this will improve
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected . This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow . Winter tires (snow tires) must always be fitted on all four wheels
.
Compatible tire pressure monitoring sensors* must be installed on
all four winter tires for the tire pressure monitoring system* to func­
tion properly ~
page 256.
Ask your authorized Audi dealer or qualified workshop for permitted
winter tire sizes . Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to
a depth of 0.157 inch (4 mm) .
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
If you have a flat tire, see notes on spare wheel
~ page 254.
Please always remember that winter tires may have a lower speed
rating than the tires originally installed on your vehicle at the time
it was manufactured . Please see~
page 256, "Speed rating (letter
code)" for a listing of the speed rating letter codes and the
maximum speed at which the tires can be driven.
The speed rating letter code(~
page 256) is on the side wall of the
tire
~ page 254.
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off. Never drive faster than the speed permitted for
your specific winter tires. This will cause damage to the tires leading to an accident and serious personal injury to you and your
passengers.
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation, loss of control, crashes and serious _,,
