contribution to good road holding and safe
handling when in good condition and properly
inflated
¢ .&. .
We recommend that all work on t ires and
wheels be performed by an authorized A udi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as we ll as the proper fa ­
cilities for dispos ing of the old tires .
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
R eplacing t ires and wheel s
Tires shou ld be rep laced at least in pairs and
not individua lly (for example both front tires
or both rear tires together).
Be s ure to read and heed the information to
the tire pressure monitoring system*
¢page 253.
Always buy rep lacement radial tires that have
the same specifications as the t ires approved
for your ve hicle by Audi. Replacement tires
must always have the same load rating speci ­
fication as the original equipment or approved
optional tires listed in the table
¢ page 239.
Audi-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving character istics, and safety of the
veh icle. The table
(¢page 239) lists spec ifica­
tions of the tir es approved for the Audi mod­
e ls covered by your Owner's Literature .
The tire pressure labe l located on dr iver's side
B-pillar (¢
page 239, fig. 179) lists the speci­
fications of the orig inal equipment tires in­
stalled on your veh icle at the time it was man­
ufactured .
Federal law requires t ire manufacturers to
p lace standard ized information on the s ide­
wall of all tires¢
fig. 182 . This information
i dent ifies and desc ribes the fundamental
characterist ics, the quality grade of the tire
and a lso provides a tire ide ntificat io n number
Tire s an d wheel s 24 7
for sa fety standard certification and in case of
a reca ll.
Tire specifications
Knowledge of tire specifications makes it eas­
ier to choose the co rrec t tires . Radial ti res
have the tire specifications marked on the
sidewa ll, for examp le:
255 /40 R 19 100 H XL
This co nta ins the following information:
P Indicates the tire is for passenger cars
(where app licab le)
255 Nom inal tire width i n mm of the tire
from sidewall edge to sidewall edge. In
general, the larger the number, the wider
the tire
40 Height/w idth ratio in percent (aspect ra -
t io)
R Tire construct ion: Radial
1 9 Rim diameter code (i n inches)
100 Load ra ting code
H Speed ra ting letter code
XL (or "xl", "EXTRA LOAD" or "RF") Indicates
t h at the t ire is a "Reinfo rced" or an " Ext ra
Load " tir e
M+S (or "M/S") Indicates that the ti re has
some mud and snow capab ility
The tires could also have the informat ion of
direction of rotation ¢
page 235 .
Tire manufacturing d ate
The manufact uring date is also indicated on
the tire sidewall (possibly only on the
inner
s ide of the wheel):
"DOT ... 2211 .. . " means, for example, the tire
was produced in the 22nd week of 2011.
Speed rating (letter code )
The speed rating le tter code on the whee ls in­
dicates the maximum permiss ible road speeds
¢ .&. in Winter tires on page 251.
P up to 93 mp h (150 km/h)
Q up to 99 mph (158 km/h)
R up to 106 mph (170 km/h)
S up to 110 mph (180 km/h)

252 Tire s and wheel s
Where snow chains are mandatory oncer­
tain roads, this normally also applies to ve­
hicles 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 insta lled 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
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r=> page 280.
A WARNING
Imprope rly tightened o r maintained wheel
bolts can becom e loose ca using loss of
c ont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts an d the
threads in the wheel hubs clean so the
w heel bolts can turn easily and be p rop­
er ly tigh tened .
- N ever grease or oil the wheel bo lt s an d
the threads in the w heel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specified
torq ue.
- Only use wheel bolts that belong to the
rim being installed.
- N ever use different whee ls bolts on your
vehicle.
- Alw ays maintain the co rrec t tighten ing
torq ue fo r th e wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out w hen the veh i­
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be­
come loose.
@ 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) . Torque whee l bolts diago­
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque w rench -preferably by an author­
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your A udi is facto ry-eq uipped w it h low aspect
ra tio tires. These tires have been tho roughly
tested and been se lected specific ally fo r your
model fo r their superb perfo rmance, road fee l
and hand ling under a variety of d riving condi ­
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The n umera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pressure. It is therefore important that low
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure i s
regularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
month and always before a long trip
r=> page 241, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ra tio tires can be d amage d more
easily by impact w it h potholes, curbs, g ull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.

262 What do I do now ?
-Make sure that passengers wait in a
safe p lace away from the vehicle and
well away from the road and traffic.
- Make sure jack position is correct, ad­
just as necessary and then continue to ra ise the jack.
- Changes in temperature or load can af­
fect the height of the vehicle.

Aft er you h ave loosened all wheel bol ts and
ra is ed the veh icle off the ground, remove and
replace the wheel as follows:
Removing the wheel
.. Use the hexagonal socket in the screwd riv ·
er handle to comp lete ly remove the top­
mos t wheel bo lt and set it as ide on a
clean
surface ¢ fig . 194 .
.. Screw the threaded end of the alignment
pin from the too l kit hand-tig ht into the
empty bolt hole
r::;, fig. 195.
.. Then remove the other whee l bolts as de­
scrib ed above.
.. Take off the whee l leaving the a lignment
pin in the bolt hole
¢ 0) .
Putting on th e spar e wheel
.. Lift the spare wheel and carefully s lide it
over the alignment pin to g uide it in place
¢ (D .
.. Use the hexagonal socket in the sc rewd river
handle to screw in and tig hten all whee l
bolts
slightly .
.. Remove the a lignment pi n and insert and
tighten the rema in ing wheel bolt slightly
like the rest .
.. Turn t he jack hand le co unter -cloc kwise to
lowe r the veh icle un til the jack is fully re­
leased .
.. Use the wheel bo lt wrench to tighten all
wheel bo lts firm ly
r::;, page 260 . Tighten
them
crosswise, from one bolt to the (ap­
proximately) opposi te one, to keep the
wheel cen tered.
(D Note
When remov ing or installing the whee l,
the rim cou ld hit the brake rotor and dam·
age the rotor . Work carefu lly and have a
second pe rson help you .
@ Tips
Never use the hexagonal socket in the han­
d le of the screwdriver to loosen or tighten
the wheel bolts.
- Pull the revers ible blade from the screw·
dr iver before you use the hexagonal
sock et in the hand le to turn the w heel
bolts.
- Whe n mount ing tires w ith unidirectional
tread design make sure the tread pat·
t er n is po inted the right way
r::;, page 2 63.
- T he wh eel bolts s hou ld be cl ean and easy
t o tu rn . Chec k for dirt and corrosion on
t he m ating surfaces of bot h the wheel
an d t he hub . Remove all d irt from these
surfaces befo re remounting the whee l.
