-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam

Please note that summer and winter tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight
means the comb ined we ight (in excess of
those standard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory -installed equip
ment (whether installed or not) .
Aspect ratio
means the ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in
dicate a low sidewall for improved steering re
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica l in those seasons . Audi recommends
using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un
balan ced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pre ssure
means the t ire p ressure recommended by the
vehicle manufacturer fo r a tire of a des ignated
s ize that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
the three hour period before the tire pressure
is measured or adjusted.
Curb weight
means the we ight of a motor ve hicle w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi
tioning and additional weight of optiona l
equipment.
E x tra load tire
means a t ire designed to ope rate a t higher
loads and at highe r inflation p ressu res than
the corresponding standard tire. Extra load
tires my be identified as "XL", "xl", "EXTRA
LOAD", or "RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the load -carry ing capacity of a s ingle
axle system , measured at the tire-ground in
terfaces.
Gr oss Vehicle Weight Rating ("GVWR ")
means the maximum total loaded we ight of
t h e vehi cle. .,.
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.
T he
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 label located on the
driver 's side B-pillar . Your Audi has 2 seating
positions. Each seating position has a safety
belt ¢
page 103, 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 is limited. 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
¢page 193, fig. 149 .
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.
Tires and wheels 197
- 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 .
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 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. 149.
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 .,.

and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
I nco rrect whee l alignment can cause exces
sive tire wea r, impair ing t he safety of the vehi
cle. If tires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All-wheel d rive
Only the wheel/tire sizes specified by the
manufacturer may be used on vehicles wi th
all-wheel drive. For details see
<:!) page 149.
A WARNING
Sudden tire failure can lead to loss of con
tro l, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fl uid away from t ires.
- 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 yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss o f vehicle control.

A WARNING ,~
Using the wrong snow chains for your vehi
cle or installing them incorrectly can in
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes. Always make sure to follow the instructions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow chain manufacturer when doing so.
@ Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to
vehicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 205
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 229.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs . They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is moving. If the tightening torque is
too high, the wheel bolts and threads can be damaged and the wheel can be
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb(± 10 Nm). Torque wheel bolts diago
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel .,.
