Sidewall
means that portion of a tire between the tread and bead.
Speed rating (letter code)
means the speed at which a tire is designed to be driven for extended
periods of time. The ratings range from 93 mph (150 km/h) to 186
mph (298 km/h)=>
page 309. You may not find this information on
all tires because it is not required by law.
The speed rating letter code, where applicable, is molded on the tire
sidewall and indicates the max imum permissible road speeds=>
& in
"Winter tires" on
page 311.
Tire pressure monitoring system*
means a system that detects when one or more of a vehicle's tires are
underinflated and illuminates 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.
Treadwear 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 306,
"Tread Wear Ind icator (TWI)" for more information on measuring
tire wear.
Uniform Tire Quality Grading
is a tir e information system developed by the United States National
Highway Traffic Safety Administration (NHTSA) that is designed to
help buyers make relative 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 (kilometers) or perform in a certain way. It simp ly
gives tire buyers additional information to combine with other
considerations, such as price, brand loyalty and dealer recommenda­
tions. Under UTQG, tires are graded by the tire manufacturers in three
Safety first
areas: treadwear, traction, and temperature resistance . The UTQG
information 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 "DO T" 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 ... 2210 ...
means that the tire was produced in the 22nd week of 2010. The
other numbers are ma rket ing codes that may or may not be used by
the tire manufacturer. Th is 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 total seating capacity as listed on the label located
on the driver's side B-pillar.
Vehicle maximum load on the tire
means that load on an individua l 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 individua l tire that is de term ined by distrib­
uting to each axle its share of the curb weight, accessory weight, and
normal occ upant weight (distr ibuted in accordance with table below
=> page 300) and dividing by two. ..,_

& WARNING
Overloading a vehicle can cause los s of vehicle control , a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle wa s designed to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control.
• The b rakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distan ce.
• Tires on a vehicle that has been overloaded can fail suddenly
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 Gro ss 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,
c ausing loss of vehicle control. •
Checking tire pressure
The c orrec t t ire pre ssur e fo r th e tires origina lly insta lled
o n yo ur veh icle is listed on th e tir e p res su re l abe l lo cat ed
on driv er's side 8-pi llar.
Th e recommended tire pressures are on the tire p ress ure labe l an d in
t he table~
page 300, "Cold tire infla tion pressure" .This means that
the pressure m ust be chec ked an d ad justed w hen the tire has not

Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the ve hicle m anufac tur er, no t the tire manufa cture r,
determines t he correct tire press ure for the t ires on your veh icle.
It is important to check the tire pressure when the t ires a re co ld .
• Read the requ ired t ire pr essure from t he t ire pr essure lab el. T he
tire pressure labe l is located on the dr ive r's side B-p illar.
• Turn t he valve stem cap co unter-clockw is e t o remove it from the

• Adjust the tire press ure to the load you are carry ing.
• Re install the valve s tem cap o n the valve.
When should I check the tire pressure?
Th e correct tir e press ure is especially import ant a t hi gh s peeds. The
pressu re s ho ul d t herefore be chec ke d at least once a mont h and
a lways before sta rt ing a jou rney. Do not fo rget to check the tire pres­

& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, loss of control, collision , serious personal injury or even
death.
• When the warning symbol appears in the instrument
cluster, stop and inspect the tires .
• Incorrect tire pressure and/or underinflation can cause
increa sed tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressures and /or underinflation 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 pressure values are located on
a sticker on the driver's side B·pillar.
• Only when all tires on the vehicle are filled to the correct pres­
sure , the ti re pressure monitoring system* can work correctly.
• 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 pres­
sures for the function of the tire pressure monitoring system*.
• Always inflate tires to the recommended and correct tire pres­
sure 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.

Tires and vehicle load limits
There are limits to the amo unt of load or weig ht that any vehicle and
any t ire ca n carry. A veh icle th at is overlo ade d w ill n ot handle well and
is more difficult to stop . Overload ing can not on ly lead to loss of
vehicle co ntro l, bu t can also d amage important pa rts of the vehi cle
and can lead to sudden t ire failure, including a b lowo ut and sudden
deflation that can ca use the vehicle to c rash.
Yo ur safety and t hat of your passengers also depends o n mak ing s ure
that load limits are not e xceeded. Vehicle load incl udes eve rybody
and everyth ing in and on the ve hicle. These load limits are tech nically
refer red to as the veh icle's
Gross Vehicle We ight Rating ("GVWR").
T he "GVWR" includes t he weight of the basic vehi cle, all factory
installed accessories, a fu ll tank of fue l, o il, coo la nt and other fluids
plus maxim um load . The maxim um load includes the number of
passenge rs that the vehi cle is intended to car ry ("seating capacity ")
w ith an ass umed we ight of 150 lbs (68 kg) for each pa ssenger at a
designat ed seating position and the tota l w eight of any l uggage in
the vehicle. If you tow a trai le r, the weight o f the t railer hitch and the tongue weight of the
loaded tra ile r must be included as part of the
veh icle lo ad .
T he
Gross Axle Weight Rating ("GAWR ") is the max imum load t hat
can be a pplied at each of the ve hicle's two axles .
Th e Gross Vehicle Weight Rat ing and the Gro ss Axle Weight Ra ting
are listed on the safety compliance s ticker label located on the
dr iver 's s ide B-pillar. Audi h as 4 seat ing pos it ions, 2 in t he fro nt and
2 in the rear for total seating capacity of 4 . Each seating pos it io n has
a seat belt =>
page 19 0, "Safety belts" .
Th e fa ct t hat there is an upper lim it to your veh icle 's Gross Vehicle
We ight Rating means that the total weight of whatever is being
c arrie d in t he ve hicle (incl uding t he weight o f a trail er hi tch and the
tongue weig ht of the loaded tra iler) is limited . The more passengers
in the veh icle or p assenge rs who are he avier than the st anda rd
we ights assumed mean that less we ight can be carried as luggage.
Th e tire pressure labe l o n yo ur Audi a lso lists the max imum combine d
we ight of alt of the o ccupants and l uggage or o ther cargo that the
vehicle ca n carry . For t he locat ion of the label=>
page 300, fig. 22 7.
& 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 de signed 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 di stan ce.
• Tires on a vehicle that has been o verloaded 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 -
i ncluding the weight of a trailer hitch and the tongue weight of a .,_

& WARNING (continued)
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.
Steps for Determining Correct
Load Limit
1.Locate the statement "THE COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehicle's placard (tire infla­
tion pressure label) =>
page 300,
fig. 227.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
Safety first
Tires and wheels -
3. Subtract the combined weight of the
driver and passengers from
"XXX" kilo­
grams or "XXX" pounds shown on the
sticker =>
page 300, fig. 22 7.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, 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- 7
SO (5 x 1 SO) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to determine how this reduces the available
cargo and luggage load capacity of your
vehicle. .,_

& WARNING
Sudden tire failure can lead to loss 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 damage, such as
grease, oil, gasoline and brake fluid away 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 loss of vehicle control. •

may or may not be used by the tire manufacturer . This i nformation is
used to contact consumers if a tire defect requires a recall.
Audi Original tire
Tires with the identification "AO" or "RO" have been specially
matched w ith your Audi. We recommend using only these tires
because they meet the highest standards regard ing safety and
driving characteristics when used correct ly. Your authorized Audi
dealer will gladly provide you with more information .
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support . Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others .

& WARNING (conti nu ed )
• Alway s use tire s, rim s and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinat ions that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
especially at high speed s. 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 tir es on your vehicle if you are not sure of
their "previous history. " Old used t ires m ay have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern .
Driving with different tire s 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 w ith 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 fa ster than the maximum speed for which the tires
on your vehicle are rated because ti re s that are driven faster than
their rated speed can fail suddenly.
• Overloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properl y inflated
and not over or underinflated.
• For technical reasons it is not always possible to u se wheels
from other veh icles- in some cases not even wheels from the same
vehicle model.
• If you install wheel tr im discs on the vehicle wheels , make sure
that the air flow to the brakes i s not blocked . Reduced airflow to
the brakes can them to overheat, increasing stopping distances
and cau sing a collision.
& W ARNING (continued )
• Run flat ti res may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassi s designed
fo r 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 o r accidents. Check with an
authorized Audi dealer or tire speciali st to see if your vehicle can
be equipped w ith run flat tires . If run flat t ires are used , they must
be installed on all four wheels. Mixing tire types is not permitted.
0 Note
• F or tech nical reasons, it is no t gene rally poss ible to use the wheel
r ims from other vehicles . This ca n hold t rue for w heels of the same
veh icle type .
• If the spare tire is different from the tires th at you have mou nted
on yo ur vehi cle (fo r ex am ple w inte r tir es o r wide profile tires), then
use the spa re t ire for a short period of time on ly and d rive with extra
care . Replace t he f lat tire w ith the tire matching the others on your
