U.S. DOT Tire Identification Number (TIN)
and tire manufacture date
This is the t ire's "serial number". It begins
wi th the le tte rs "DO T" and indica tes 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 manufacture.
For example, the numbers 2213 mean that
the tire was produced in the 22nd week of
2013 . The other numbers are marketing co ­
des that may or may not be used by the tire
manufacturer. This information is used to con­
tac t consume rs if a tire defect requires a re­
call.

collis ion and serio us personal i nju ry .
- A lways 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 yea rs
old can only be used in an emergency
and then w ith specia l care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of the ir "previo us histo­
ry." O ld used tires may have been dam­
a ged even thoug h the damage cannot be
seen that can lead to sud den tire fa ilure
and loss of vehicle control.
- All fo ur whee ls must be fitted with radial
tires of the same type, size (rolling cir­
cumference) an d the same tread pattern . ..,

Speed rating (letter code)
for a listing of the
speed rat ing letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code
( c> page 184) is
on the side wall of the tire
c::> page 192 .
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
w inte r tires . This will cause damage to the
tires leading to an acc ident and serious
personal injury to you and yo ur passen­
gers .
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immed iately.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
wh ich 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 winte r tires and all-whee l
drive tempt you into taking extra r is k s . A l­
ways remember:
- When brak ing, an a ll-wheel drive vehicle
hand les in the same way as a front drive
vehicle.
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.

@) For the sake of the env ironment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be fitted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used .
If you are go ing to use snow chains, then you
must install them on the front wheels at
least .
The snow chains mus t have low-prof ile links
and must not be th icker than 0 .53 inch
(13.5 mm), includ ing the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (D . For safety reasons cover caps must then
be fitted over the wheel bolts . These are avail ­
able from authorized Aud i dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or insta lling them incorrect ly can in­
crease the risk of loss of cont ro l 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 dr iv ing on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direc t con­
tact with the whee l rim, can scratch or
damage it . Therefore, make sure that the .,.

snow cha ins a re suitab ly covered. Check
the position of the snow chains after driving a few yards and correct if neces ­
sary. Follow the instr uctions from the
snow cha in manufacturer when doing so.
{O) Tips
Where snow cha ins are mandatory oncer­
tain roads, this norma lly also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correc t torque .
The design of whee l bolts is matched to the
factory installed r ims . If different rims are fit ­
ted, the correct wheel bolt s with the r ight
length and correctly shaped bol t heads mus t
be used . This ensures that wheel s are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same model
Q page 228.
A WARNING
Imprope rly tig htened o r maintained whee l
bolts can be come loose ca using loss of
cont ro l, a co llision and serious person al in­
jury .
- Always keep the w heel bol ts and the
t h reads in t he wheel hubs clean so the
wheel bolts can t urn easily and be p rop ­
er ly t ightened .
- N ever grease or oil the wheel bo lt s an d
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that be long to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
- Always mai ntai n the co rrect tighte ning
torq ue for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor- que of the whee
l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig hte ning torq ue is
too high, the w heel bolts a nd threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for t he whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torque whee l bolts diago­
nally . After changing a whee l, the to rq ue
must be checked as soon as possible with a
torque w rench - prefe rably by an author­
iz ed A udi dealer or quali fied workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w ith low aspect
ratio tires. These tires have b een tho ro ughly
tested and been se lected specifically for your
model for their supe rb performance, road fee l
and hand ling under a variety of driving condi­
t ions . Ask your author ized Audi dealer for
more de tails .
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 rep resents the ratio
of the tire 's s idewa ll height in relation to its
t read width exp ressed in percentage. Conven­
tiona l tire s have a he igh t/w idth rat io of 60 or
more.
The p erformance of low-a spect-ratio tire s is
particularly sensitiv e to improper inflation
pre ssure. It i s ther efore important that low
aspect ratio tires are inflated to the specified
pre ssure and that the inflation pre ssure i s
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always before a long trip
Q page 187, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith po tholes, curbs, gul lies ..,.

to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both th e whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unti ng the wheel.
Notes on wheel change
Pl ease read the informa tion ~ page 192, New
tires and replacing tires and wheels,
if you are
going to use a spare t ire which is different
from the tires on your vehicle.
After you change a tire :
-Check the tire pressure on the spare imme­
diately after mounting .
- Have the wheel bolt tightening torque
che ck e d with a torqu e wrench a s soon as
possible b y your auth orized Audi dealer or
a qualified ser vice station .
- With steel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of
90 ft lb (1 20 Nm ).
- If y ou notice while changing a tire that the
wheel bolts are co rroded and difficult to
turn , then the y should be repl aced befo re
you check the t ightening torque . -
Repla ce the flat ti re with a new one and
have it installed on your veh icle a s soon as
possible. Remount the wheel cove r.
Until then , dr ive with extra care and at re­
duced speed s.
_& WARNING
-
- If you are going to eq uip your vehicle
wit h tires or rims which differ from those
which were factory installed, then be
sure to read the information

New tires and replacing tires and
wheels.
- Always store the tools secu rely i n lug­
gage compartment. Othe rwise, in a n ac­
cident or s udden maneuver they cou ld fly
forwa rd, causi ng injury to passengers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A un idirectional tire can be identified by ar­
rows on the sid ewall ,
which point in the direc­
tion of the rota tion. Yo u m ust follow the
specified direction of rota tion. This is ne ces sa ­
r y in order fo r these tires to develop t heir op ­
timum character istics regard ing grip, road
noise, wear, and hydrop laning.
