U.S . DOT T ire Identific ation Numbe r (TIN)
and tire manufacture date
This is the t ire's "serial number" . It begins
with the lette rs "DO T" and indicates that the
tire meets all federal sta ndards. The next two
n umbers or le tters indica te the p la nt where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
F or example, the numbers 2209 mean that
the t ire was produced in the 22nd week of
2009 . The other numbers are marketing co­
des that may or may not be used by the t ire
manufacturer . This information is used to con ­
tact consume rs if a tire defect requires a re­
call.
Aud i Original tire
Tires with the ident ificat io n "AO" or "RO" have
been spec ially matched with your Aud i. We
recommend using only t hese tires because
they meet the highest standards regard ing
safety and driving charac ter is t ics when used
correctly . Yo ur au thori zed Au di dealer w ill
g lad ly provide you with more information.
Maximum Load Rating
This number indicates the maximum load in
kilograms a nd pounds that ca n be carried by
the tire .

.&_ WARNING ~
- Using incorrect o r unmatched tires and/
or wheels or improper tire and wheel
comb inat ions can lead to loss of control,
col lis ion and serious personal inj ury.
- Always use t ires, rims and whee l bolts
that meet the specifications of original
factory- installed tires or other combina­
tions that have been specifically ap­ proved by the vehicle manufacture r.
- T ires age even i f they are not being used
and can fail sudden ly , e specially at hig h
speeds. Tires that are more than 6 ye ars
old can only be used in an emergency
an d then w ith speci al care and at lower
speeds .
- Never mo unt used t ires on your veh icle if
you are not sure of thei r "previous histo­
ry." O ld used tires may have been dam ­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.
- All fou r whee ls must be fitted with radial
tires of the same type , size (rolling cir­
cumference) and the same tread pattern.
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
contro l.
- If the spa re tire is not the same as the
tires that are mounted on the vehicle -
for examp le w ith winter t ir e s -only use

228 Tires and wheels
The speed rating letter code( ¢ page 224) is
on the side wall of the tire
¢ page 223.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires. This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING I>=
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking , an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Audi dealer on which tire sizes snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13 .5 mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
¢ (!) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
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 in­
structions 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 on
certain roads, this normally also applies
to vehicles with All Wheel Drive .
- If snow chains are insta lled, the tire
pressures shou ld not be stored in the tire
pressure monitoring system (TPMS).
Otherwise the system could malfunction
¢page 232.
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 wit h the right
length and correctly s haped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the bra ke system f unctions
cor rectly .
In certain circumstances, you may not use
wh eel bolts from a differ ent vehicle -even if it
i s the same mode l.
.&, WARNING
Improperly tig hte ned o r maint ained wheel
bol ts can become loose ca using loss of
cont ro l, a co llision and ser ious persona l in ­
jury.
- Always keep the wheel bolts an d the
threads in the wheel hubs clean so the
whee l bolts can tu rn easily and be pro p­
er ly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the w heel hubs. They can
become loose w hile driving if greased or
o iled, even if tightened to the specified
torq ue.
- Only use wheel bolts t hat belong to the
r im being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tighten ing
torq ue for the wheel bo lts t o reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 229
que of t he whee l 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 lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as so on as possible with a
torq ue w rench -prefe rably by an au thor ­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng u nder a var iety of driving condi­
tions . Ask your au thorized Aud i dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numera l represen ts the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in perce ntage. Conven­
tiona l tires have a he ight/w idth ratio of 60 o r
more.
The performance of low-a spect-ratio tires i s
particularly sensitive to improper inflation
pre ssure.
It is therefore important that low
aspect ratio tires are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 218, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.

236 What do I do now?
-After installing the compact spare wheel,
the tire inflation pressure should be
checked and, if necessary, increased to
60 psi (4.2 bar).
- The load carrying capacity is marked on
the tire sidewalls and must not be ex ­
ceeded.
- After installing the compact spare wheel,
make sure that you remount the flat tire
in its storage area properly.
- The compact spare tire should be proper­
ly remounted in its storage area as soon
as the standard road tire can be re­ placed .
- Because the compact spare tire was spe­
cifically designed for your vehicle, it must not be used on any other vehicle .
Likewise, compact spare wheels from
other vehicles must not be used on your
vehicle.
- The compact spare tire must not be
mounted on any other wheels, nor must
standard tires, snow tires, wheel covers
or trim rings be used with the compact
spare wheel. If such use is attempted,
damage to these items or other vehicle
components may occur .
(D Tips
Check the inflation pressure of the com­
pact spare tire (60 psi/4.2 bar) periodically
to keep the tire ready for use.
Wheel change
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel .
.. After you experience a tire failure, pull the
car well away from moving traffic and try to
reach
level ground before you stop c:> ,&. .
.. All passengers should leave the car and
move to a safe location (for instance, behind
the guardrail)
c:> _&. .
.. Apply the parking brake firmly c:> _&. .

tance off the road. Turn off the engine,
turn the emergency flasher on and use
other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe place away from the vehicle and well
away from the roadway and traffic .
- To help prevent the vehicle from moving suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac ­
ing the automatic transmission in "P"
(Park) , or engaging a gear in a manual
transmission will
not prevent the vehicle
from moving.
