U.S. DOT T ire Identification Number (TIN )
and tire manufactur e date
This is the t ire's "serial numbe r" . It begins
with the le tters "DOT" and indicates that the
tire meets all federal standards . The next two
numbers or letters indicate the p lant where it
was manufactured, and the last four numbers represent the week and year of manufactu re.
Fo r example, the numbers 2211 mean that
t he t ire was produced in the 22nd week of
2011. 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.
Audi Original tire
Tires with the ident ificat ion "AO" or "RO" have
been spec ially matched with your Aud i. We
recommend using only these tires because
they meet the highest standards regard ing
safety and driving charac ter istics whe n used
correctly. Yo ur authorized Audi dealer will
g lad ly provide you with more informat ion.
Tire ply composition and materials used
The numbe r of p lies ind icates the numbe r of
l ayers of rubber -coa ted fabric in the t ire. In
general, the greater the number of p lies, the
mo re weight a tire can support . Tire manufac ­
turers also must indicate the materials in the

_&. WARNING
-Using incorrect o r unm atc hed tires and/
or wheels or improper tire and wheel
comb inat ions can lead to loss of control
,
collision and serio us personal inj ury .
- Always use t ires, rims and whee l bolts
that meet the specifications of original
factory- insta lled tires or other combina­
tions that have been specifically ap­ proved by the vehicle manufacturer.
- Tires age even if they are not being used
and can fai l sudden ly, especially at hig h
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at lower
speeds .
- Never mount used tires on your veh icle if
you are not sure of the ir "previous histo­
ry ." O ld used tires may have been dam­
a ged even thoug h the damage cannot be
seen tha t can lead to sudden tire fai lure
and loss of vehicle control.
.
- All fo ur whee ls must be fitted wit h ra dial
tires of the same type, size (rolling cir­
cumference) and the same tread pattern . ..,

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 245.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile d riving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 213
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 soon 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 roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi 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 numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s 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 202, 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 ..,.

or ridges on the road, part icu larly if the tire is
u nderinflated.
I n o rder to m inim ize the o ccurrence of impact
damage to the t ires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended infla tion
pressures. Check your t ire pressure every
2,000 miles (3,000
km) and add air if neces ­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
t h rough or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause t ire failure . If you be lieve that a
t ire may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wea r mo re quick ly than oth­
ers.
- Please a lso remember that, wh ile these t ires
deliver respons ive handling, they may ride
l ess comfortably and make mo re no ise than
other choices.
Reduced performance in winter /co ld
sea son condit ion s
All ti res a re des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. If
you dr ive under those circumstances, you
should equip your vehicle with all -season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or all-season tires specified
fo r your vehi cle, or their eq uivalent. Refer to
q page 211
for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, incl uding the spare ( if provided),
sho uld be checked monthly when co ld and in­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire i n­
flat ion p ressure label, you should dete rmine
the p roper t ire infla tion p ress ure fo r th ose
t i res.)
As an added safety feature, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPM S) tha t illum inates a low ti re
pressure tel ltale when one o r more of your
tires is significant ly under-inflated . Acco rding­
l y, when the low tire pressure telltale i llumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflat ion al ­
so reduces fuel effic iency and tire tread life ,
and may affect the vehicle 's hand ling and
stopp ing abili ty.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low tire pressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate when
the sys tem is not operating p roperly . Th e
T PMS ma lfunction indicator is combined w ith
t h e low tire pressure te lltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then ..,_

216 Tires and wheels
Inflate the tire pressure to the proper
pressure as indicated on the vehicle's tire
pressure label¢
page 200. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle .
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or accidents
could also result.
- If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module .
@ Tips
-The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction .
- The tire pressure monitoring system on
your Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall ¢
page 207. We recom­
mend using these tir es.
Reset tire pressure monitoring system

~ Move the switch @¢ fig. 156 on the e lec­
tric a ir pump
ll to posi tion I. After 5 mi­
nutes, tire pressure must have reached at
least 1.8 bar.
~ Switch the electric a ir pump off - switch in
position
0 . If the requ ired tire pressure of at
least 1.8 bar has not been reached, it is not
poss ible to make a repa ir with the tire seal ­
ant. Seek professional ass istance.
Disassembling Tire Mobility System
~ Remove the hose from the valve and pu ll
the plug out of the socket.
~ Screw the dust cap onto the valve.
~ Place the empty sealant bottle back in the
original packag ing and clip it in place under
the floor so that no tire sealant can run out
into the vehicle.
~ Place the elect ric air pump in the luggage
compartment for the time being.
~ Start driving right away so that the sealant
is distributed in the tire.
A WARNING
-Follow the manufacturer's safety instruc­
t ions on the deca l for the air pump and
the sealant bott le.
- If a t ire pressure of 1.8 bar cannot be
achieved after pump ing for 5 m inutes,
the tire is too severely damaged. Do not
continue to drive .
- Seek profess ional assistance if it is not
poss ible to repair the tire with the tire
sealant.

6 min utes.
What do I do now? 223
(D Tips
-Do not operate the electric air pump for
more than 6 minutes witho ut stopping,
otherwise it can overheat. When the a ir
pump has coo led down, you can continue
to use it.
- If sealant has escaped, allow it to dry,
then you can peel it off.
Final check
App lies to vehicles: wit h Tire Mobility System
After driving for a short distance, tire
pressure must be checked
~ After d riving for about 10 m inutes, stop
and check the tire pressure.
~ If tire pressure is still at leas t 1.3 bar, in­
flate the tire to specified pressure (see driv­
ers side B -pillar), drive to the next repair
shop and have the tire and the sealant bot­
tle replaced.
~ If tire pressure is less than 1.3 bar, the t ire
is too severely damaged. Do not cont inue to
drive . Seek professional assistance.
A WARNING
If t ire pressure is less than 1.3 bar after
driving for 10 minutes, the tire is too se­
ve rely damaged. Do not continue to drive.
Seek professional ass istance .
(D Tips
After a tire repair, have the sealant bottle
replaced at a dealership. This restores full
funct iona lity to the Tire Mobility System.
