The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char­ acteristics of the vehicle and can make a major contribution to good
road holding and safe handl ing when in good condition and prop ­
erly inflated =>& .
We recommend that al l work on tires and wheels be performed by
an authorized Audi dealer . They are familiar with recommended
procedures and have the necessary special too ls and spare parts as
we ll as the proper facilities for disposing of the o ld tires .
Authorized Audi dealers have the necessary information about tech ­
n ical requirements for insta lling o r changing tires and rims .
Repl ac ing t ires and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together).
On vehicles with tire pressure moni toring system*, be sure to read
and heed the information=>
page 287.
Always buy replace ment radia l tires tha t have the same specifica ­
tions as the tires approved for your vehicle by Audi . Replacement
tires must always have the same load rating specification as the
original equipment or approved optional tires listed in the table
=>
page 271.
A udi -appr oved specificat ion tires a re specially matched t o your
vehic le and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle
. T he tab le

page 271) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located either on driver's side B -pi llar or
insi de the fuel filler flap(=>
page 271, fig. 208) lists the specifica ­
tions of the original equipment tires installed on your vehicle at the
time it was manufactured.
Federa l law requires tire manufacturers to place standardized infor ­
mation on the sidewa ll of all tires=>
page 279, fig. 211. This informa ­
tion identifies and descr ibes the fundamenta l characteristics, the
quality grade of the tire and a lso prov ides a tire identification
number for safety standa rd certif ication and in case o f a recall.
Tire sp ecifi cations
Knowledge of tire specifications makes it easier to choose the
correct t ires. Rad ial tires have the tire specifications mar ked on the
sidewal l, for example:
P235 / 45 R 18 95 Y
This c onta ins the fo llowing informatio n:
P Indicates the tire is fo r passenger cars (where appl icab le)
2 3 5 Nominal tire width in mm of the tire from sidewall edge to s ide -
wa ll edge. In general, the larger the number, the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction: Radial

Tire manufacturing date
The manufacturing date is also indicated on the tire sidewall
(possibly on ly on the
inner side of the wheell:
"DOT ... 2209 ... " means, for example, that the tire was produced in
the 22th week of 2009.
Speed rating (letter code)
The speed rating letter code on the wheels indicates the maximum
permissible road speeds =:,
& in "Winter tires" on page 284.
P up to 93 mph (150 km/h)
Q up to 99 mph (158 km/h)

U.S. DOT Tire Identification Number (TIN ) and tire
manufacture date
This is the tire's "serial number". It begins with the le tters "DOT"
and indicates that the tire meets all federal standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac-

ture. For example, the numbers 2209 mean that the tire was
produced in the 22th week of 2009. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer . This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi ­
cate 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 carr ied by the tire .
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades=:, page 283.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system*
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans ­
mits this information to the tire pressure monitoring system*. If you
are going to replace the wheel rims on your vehicle, make sure the
new rims also have these sensors . The sensors must be compatible
with the tire pressure monitoring system* on your vehic le .
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring
system* wil l not work properly. In this case, the tire pressure moni -.,_

In some heavy snow areas, local governments may require true
winte r or "snow" tire s, those wi th ve ry deeply cut tread. These tires
should only be used in pairs and be instal led on a ll four wheels .
M ake s ure you p urchase snow ti res that are the same size and
cons truct ion type as the o the r ti res on your v ehicle.
I f your vehic le is equipped with al l-wheel drive*, this will improve
t raction during w inter dr iving, even with the s tandard tires .
H owever, we strongly recommend that you a lways equ ip all four
whee ls on y our vehic le wi th correc tly fitted winte r tires or all-seas on
tires, when winter road conditions are expected. This also improves
th e ve hic le 's brak ing performance and red uces s to ppi ng d ista nce s.
Summer t ires p rov ide less gr ip o n ice and s now. Winter tires (snow tires) must a

I f your veh icle is equipped with a ti re pre ssure monitoring system*,
compatible t ire pressure mon itoring sensors must be installed on
a ll four winte r tires for the system to function properly ~
page 281.
Ask your aut hori zed Audi dealer or quali fied wo rksho p for perm itte d
winter tire sizes . Use only radial winter tires.
Winter tires lose thei r effec tive nes s when the tread is wo rn down t o
a depth of 0.157 inch (4 mm).

& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum 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
pa ssengers.
& WARNING
Driving faster than the maximum speed for whi ch the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , los s of control , crashes and seriou s

Wheel bolts
Wheel bolts must always be tightened to the correct
torque .
The design of wheel bo lts is matched to the factory installed rims . If
different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that
whee ls are fitted securely and that the brake system functions
correctly .
I n certain circumstances, you may not use wheel bolts from a
different vehicle -even if it is the same model~ page 318.
& WARNING
Improperl y tightened or maintained wheel bolt s can be come loose
c au sing lo ss of control , a co llis ion and seriou s personal injur y.
• Alwa ys keep the wheel bolt s and the th reads in the wheel hubs
c lean so the wheel bolt s can turn ea sily and be properl y tightened.
• Never gre ase or oil the wheel bolt s and the thre ad s i n the wheel
hub s. They can become lo ose while drivin g if gre ased or oiled ,
e ven if tig hten ed to th e specifi ed torque .
• Onl y use wheel bo lt s th at bel ong to the rim being in sta lled.
• Nev er use differ ent wheel s bolt s on your vehicle.
• Alway s m aintai n the corre ct t ightenin g to rq ue for the whee l
bo lt s to r edu ce the ri sk of a whe el los s. If the tighten ing torque of
t h e w heel bolt s is too l ow, they c an loose n a nd com e out when th e
v ehicl e is mov ing . If th e tighte ning torque is t oo high, the whe el
b ol ts an d threads can be dam ag ed and the whee l can become
loo se .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
tolerance of ± 7,4 ft lb(± 10 Nm). Torque whee l bolts diagonally.
After changing a wheel, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi
dea ler or qua lified workshop .•
Low aspect ratio tires
Your Audi is fac tory-equipped with low aspect ratio tires. These tires
have been thorough ly tested and been selected specifically for your
model for their superb performance, road feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated by a numera l of 55 or
l e ss in the tire's size designation . The numera l represents the ratio
of the tire's sidewa ll height in relat ion to its tread w idth expressed
in percentage. Conventiona l tires have a height/width ratio of 60 or
more .
T he perform ance of lo w-as pect-rati o tire s is part ic ul arl y s ensit ive to
improp er infla tion pr essure. It i s there fore important that low
a s pect ra tio tir es are inflated to the sp ec ified pre ssure an d th at th e
i nfl ation pre ssure is regularl y checked and m aintained . T ir e pres ­
s ure s should b e checked a t lea st once a month and alw ays before a
long trip~ page 274, "Checking tire pressure".
What you can d o to avoid tire a nd rim dama ge
Low aspect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehic le, we recommend that you observe the fo llowing
precautions:
• Always maintain recommended inflation pressures . Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary .
• Drive careful ly on roads with potholes, deep gullies or ridges.
The impact from driving through 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 Audi dealer. Replace a
damaged tire as soon as possible .
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear. Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventua lly cause tire failure. If
you believe that a tire may have been damaged, replace the tire as soon as possible .
• These tires may wear more quickly than others .
• Please a lso remember that, while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in vvinter /cold season
conditions
All tires are designed for certain purposes. The low aspect ratio,
ultra high performance tires originally installed on your vehicle are
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If
you drive under those circumstances, you should equip your vehicle
with all -season or win ter tires, which offer better traction under
those conditions . We suggest you use the recommended snow or
all -season tires specified for your vehicle, or their equivalent .
