Your vehicle is normally factory equipped with
tires, which possess excellent driving charac­
teristics and give your Audi optimum driving
comfort. An electronic speed limiter

U.S . DOT Tire Identification Numbe r (TIN)
and tire manufacture date
This is the t ire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federal standards. The next two
numbers or letters indicate the plant whe re it
was manufactured, and the last four numbers
represent the week and year of manufacture.
F or example, the numbers 2212 mean the tire
was produced in the 22nd week of 20 12. The
other numbers are marketing codes that may
or may not be used by the t ire manufacturer.
This information 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 with your Audi. We
recommend using only these tires because
they meet the highest standards regarding

correct ly . Your authorized Audi dealer will
gladly provide you w ith 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
genera l, the greater the number of plies, the
more weight a tire can support. Tire manufac ­
turers also must indicate the materials in the
tire, which include steel, nylon, polyester, and
others.
Maximum Load Rating
This number indicates the maximum load in
kilograms and pounds that can be carried by
the tire.
Tire quality grading for treadwear,
traction , and temperature resistance
Tread wear, traction and temperat ure grades
<=> page 2 63.
Maximum Permissible Inflation Pressure
Th is number is the greatest amount of air
pressure that should ever be put in the tire
under normal driving conditions.
A WARNING
-Using incorrect or unmatched tires and/
or wheels or improper tire and wheel
comb inat ions can lead to loss of control,
coll is ion and serious personal injury.
- Always use tires, rims and wheel bolts
that meet the specif ications of original
factory- installed tires or other combina­
tions that have been specifically ap­
proved by the vehicle manufacturer.
- T ires 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 specia l care and at lower
speeds.

26 6 T ire s and whee ls
- 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

and the hub. R emove a ll dirt from these
su rfaces before remo unt ing the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spa re tire with a t read patte rn
i n te nded fo r use in a specific direction, please
note the fo llowing:
- T he direction o f rotation is marked by a n ar­
row on the side of the tire.
- If the spare t ire has to be in stalled i n the in ­
corre ct d irection, use the sp are tire on ly
temporarily since the t ire will not be a ble to
achieve its optimum perfo rmance character­
ist ics with rega rd t o aquaplaning, noise and
wea r.
- We recommend t hat you pay pa rticular at­
tent ion to this fact during wet weat her and
t h at y ou adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed o n your ve hicle as soon as
poss ible to restore th e handli ng a dvantages
