250 Tire s and wheel s
-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 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
age.

Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard 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 th ese
items are availab le as factory -installed equip­
ment (whether installed or not) .
Aspect ratio
means t he 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 separation
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 . Aud i 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 pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted
s iz e that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
t h e three hour period before the tire pressure
is measured or adjusted.
Curb weight
mea ns the we ight of a motor ve hicle with
standard equipment in cl uding the max imum
capacity of fuel, oil, and coolant, air condi ­
tioning and additional weight of optiona l
equipment.
Extra load tire
me ans a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -c a rry ing c apac ity of a s ingle
axle system , measured a t the tire-ground in­
terfaces.
Gross Vehicle Weight Rating ("GVWR ")
mea ns the maximum total loaded we ight of
t h e ve hicl e. .,.

260 Tires and wheels
-Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pared to all-wheel drive (quattro ®).
- Please rotate tires as shown
¢fig. 207.
- Extra care must be taken when rotating di-
rection-specific tires
¢ page 2 78.
Wheel balancing
The wheels on new vehicles are balanced .
H owever, various situations during everyday
driving can cause them to become unbal­
anced , resu lting in vibrations you can usually
feel through the steering wheel.
Unba lanced wheels must be rebalanced to
avoid excessive wea r on steering , suspens ion
and tires . A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect whee l alignment can cause exces­
sive tire wear, impair ing the 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 Drive
Vehicles with quattro® must always have ti res
of the same size, construction and tread type.
F or details see
¢page 203.
A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire 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 laning" 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 be ing 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 specia
l care and at lower
speeds.
- Never mount used tires on your 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 sudden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in.

- Remove snow chains before driving on
roads not covered with snow to avoid
damaging t ires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into d irect 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.
- If the Adaptive Air Suspension should
malfunction, do not mo unt or use snow
cha ins beca use the veh icle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the veh icle.
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with All Wheel Drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
cor rectly .
In certain circumstances, you may not use
wheel bolts from a different vehicle - even if it is the same model
~ page 298.
A WARNING
Imprope rly tightened o r maintained wheel
bolts can be come loose caus ing loss of control, a col
lision and serio us personal in­
jury.
- Always keep the wheel bo lts and the
threads in the whee l hubs clean so the
wheel bo lts 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 driv ing if greased or
oiled, even if t ightened to the specified
torque.
- Only use wheel bolts that belong to the rim being installed .
- Never use different wheels bolts on your
veh icle.
- Always ma intain the correct tightening
torque for the whee l 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 mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be ­
come loose .
(D Note
The specified torque for the whee l bolts is
90
ft l b (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque whee l bolts diago ­
nally . After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualif ied workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
ratio tires . These tires have been thoroughly
tested and been se lected specifically fo r your
model for their superb perfo rman ce, road fee l
and hand ling under a variety o f driving condi­
tions. Ask your authorized A udi dealer for
more details .
T he low aspect ratio of these tires is ind icated
by a numera l of
55 o r less in the tire's s ize
designation. The numeral rep resents the ratio
of the tire's sidewa ll height in relation to its
ll-

-When removing heavy components like
these, anchor vehicle to hoist o r add cor ­
respond ing weig hts to mai nta in the cen ­
ter of g ravity. Otherwise, the vehicle
m ight tilt o r slip off the hois t, causi ng
ser ious persona l injury .
Q) Note
-Be awa re of the fo llow ing points befo re
li fting t he vehicle:
- The vehicle should never be lifted or
jacked up from underneath the engine
oil pan, the transmission housing , the
front or rear axle or the body side members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
i nserted between the floor jack and
the lift points .
- Before driv ing over a workshop hoist,
check that the veh icle weight does not
exceed the permissibl e lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear­ ance between the hoist and low parts
of the vehicle.
