24 6 T ire s and whee ls
The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
vehicle equ ipment dur ing the model year, a l­
ways compare the tire size designation on the
tire pressure labe l on your vehicle with the
tires on your vehicle . Make sure that the tire
si ze information on the vehicle label is the
same as the si ze of the tires on the vehicle.
This is especially important if the vehicle be ­
longs to someone else or you bought the veh i­
cle with different rims/tires or you bought the
vehicle as a p reviously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
ve hicl e. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR") . The Gross Ax le Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker labe l located on the
driver 's side B-p illar . The tire pressure label on
your Aud i lists the maximum combined
weight of all of the occupants and luggage or
o ther cargo that the vehicle can carry. For the
l ocation of the tire pressu re labe l
i=:> fig. 191.
A WARNING
Overloading a vehicle can cause loss of ve ­
hicle control, a cras h or other accident, se­
r ious personal injury, and even death.
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of a 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 causing loss of con­
trol and a crash . -
Always make sure that the total load be­
ing transported - including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's G ross Vehi­
cle Weight Rating.
A WARNING
-- I ncorrect tire pressures and/or underin-
flation can lead to a serious or fatal acci­
dent.
- I nco rrect tire pressures and/or underin­
flation cause increased ti re wear and can
affec t the handling of the vehicle .
- I nco rrect tire pressures and/or underin­
flation can a lso lead to s udden t ire fail­
ure, including a blowou t and sudden de­
flation, ca using loss of veh icle cont ro l.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressur e label located on driver's side 8-pil ­
lar .
The recommended tire pressures are on the
t ir e pressure label and in the table
i=:> page 244, Cold tire inflation pressure.This
means that the pressure m ust be checked and
adjusted when the t ire has not been dr iven 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 inter nal frict ion as it flexes in
u se . T he t ire pressure is higher when the tire
has warmed up t han whe n it is "co ld. "
It is the inflation pressure in a "co ld" t ire that
counts . The refore, you should never let a ir out
of a wa rm tire to match "Cold t ire inflat ion
pressure" recomme ndat ions
i=:, page 244 . The
t ir es wo uld then be unde rinflated and co uld
fail suddenly .
T he t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
m aximum cap acity for the new, or ig inal
equipmen t tires tha t were on your vehicle at ..,.

248 Tire s and whee ls
- Only when all tires on the vehicle are fi l­
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 funct ion of the tire pressure mon itor­
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated ti res bend
more, letting them get too hot resu lting
in tread separation, sudden ti re fail ure
and loss of control.
- Excess ive speed and/overloading can
cause heat bui ld -up, sudden ti re fail ure
and loss of control.
- If the tire press ure is too low or too high,
the tires wi ll wear prematurely and the
vehicle will not hand le we ll.
- If the tire is not flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
Driving without va lve stem caps can cause
damage to the tire va lves. 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
Underinf lated tires will a lso increase the
fuel consumption.
Tires and vehicle load limits
There are limits to the amount of load or weight that any veh icle and any t ire ca n carry.
A veh icle that is overloaded w ill not handle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of veh icle contro l, but can also damage important parts of the
vehicle and can lead to sudden tire fai lure, in­
clud ing a b lowout 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 veh icle. These
load lim its are technically referred to as the
vehicle's
G ro ss Vehicl e We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
intended to car ry ("seat ing capac ity") with an
ass umed we ight of 150 lbs (68 kg) for each
passenge r at a designated seating position
and the total weight of any luggage in the ve ­
hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
G ro ss Axle We ight R ating ("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 comp liance sticker label located on the
driver's side B-pillar . Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rear for
total seating capacity of 5 . Each seating posi­
t ion has a safety belt
Q page 136, 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 car­
ried in the vehicle ( includ ing the weight of a
t ra ile r hi tch and the tongue weigh t of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug-
gage.
~

The 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
c:::>fig. 191.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious 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 vehicle con­
trol.
- 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 overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
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 QC-
Tires and wheels 249
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure label)
¢ fig. 191.
2. Determine the combined weight of the driver and pas­sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and pas­sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ fig. 191.
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
cle, the amount of available
cargo and luggage load ca­ pacity is 650 lbs. (1400-7 50
(5
X 150) = 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 trail­
er will be transferred to your
vehi cle. Consult thi s manual
to determine how this re­
duces the available car go
and luggage lo ad capacity of
y o ur vehicle .
.,. Check the tire sidewall
(9 fig . 195) to de termine the
de signated load rating for a
s pe cifi c tir e.
Tire service life
The s ervi ce life of tires dep ends on a lot of
different things including proper installation
and balancing, correc t tire pressu re and driv­
ing style.

Tire pressure
Incorrect t ire pressure ca uses premature wear
and can cause sudde n tire blow-out. For this
reason, tire pressure must be checked at least
o nce a month ¢
page 246.
Driving style
Driving fast around c urves, heavy acce lerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
Fo r all four tires on your ve hicl e to have the
same service life, we recommend that the
front and rear t ires a re rotated according to
the tire manu fact urer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from t he
veh icle service interva ls outlined in your
Warranty
& M aintenance booklet.
- The longer one tire is used in one location
o n t he vehicle, the more it wears at certain
points; theref ore, we recommend t hat y ou
follow the tire manufacturer's suggested
tire rotation int ervals .
- Veh icles w ith front-wheel dr ive experience
more tread wear on the fro nt wheels com­
pa red to a ll-wheel d rive ( quattro ®).
- Please rotate tires as shown¢
fig. 194.
- Extra care must be taken when rotating di-
rection-specific tires ¢
page 268.
Wheel balancing
The wheels on new ve hicles are balance d.
Howeve r, various s ituations during everyday
dr iv ing can cause them to become unba l­
anced, resulti ng in vibrations you can usually
feel th rough the steer ing wheel.
