210 Tir es and whe els
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.S mm), including the lock .
Remove wheel center covers and tr im discs
before putting snow cha ins on your vehicle
¢ Q) . For safety reasons cover caps must the n
be fitted over the whee l bolts. These are avai l­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for yo ur vehi ­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
ser ious personal inj ury.
- Snow chains are ava ilable in different
sizes. Always make sure to follow the in­
struct ions provided by the snow chain
manufacturer .
- When driving w ith snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions.
([) Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wear ing the snow
chains down unnecessar ily.
- 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
sa ry. Follow the i nstructions from the
snow cha in manufacture r when doing so.
(D Tips
Where snow chains are mandatory on cer­
tain roads, th is normally a lso applies to ve­
hicles with All Whee l Dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
T he design of wheel bo lts is matched to the
factory installed rims. If different rims are fit­
ted, the correct whee l bolts with the right
l ength and correctly shaped bolt heads must
be used. Th is ensures that wheels are fitted
securely and that the brake system functions correctly.
In certa in circumstances, you may not use
whee l bolts from a different vehicle -even if it
is the same model
¢page 243.
A WARNING
-Imp roperly t ightened or ma inta ined wheel
bo lts can become loose causing loss of
control, a coll is ion and serious pe rsonal in­
jury.
- Always keep t he wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the whee l hubs . They can
become loose while driving if g reased or
oiled, even if tightened to the specified
torque.
- Onl y use whee l bolts that belong to the
rim being installed.
- Never use different wheels bo lts on yo ur
vehicle .
- Always maintain the correct tightening
torque for the whee l bolts to reduce the
risk of a whee l 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 tightening torque is
too high, the wheel bolts a nd threads
II>-

can be damaged and the wheel can be­
come loose.
@ Note
The specified torque fo r the wheel bo lts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torque wheel bo lts diago­
nally. After chang ing a wheel, the torque
must be checked as soon as possib le wit h a
torque wrench -preferab ly by an author­
ized Aud i dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio t ires. These t ires have been thorough ly
tes ted and been selected spec ifica lly for your
model for the ir superb pe rformance, road feel
and handling under a variety of driving condi­
tions . Ask your a uthorized Audi dea le r for
more deta ils.
The low aspect ratio of these tires is indicated
by a numeral of
55 or le ss in the tire's size
designation. The numeral represents the ratio
of the tire's sidewall height in relat ion to its
tread width expressed in percentage . Conven­
tional tires have a height/width ratio of 60 or more .
The perfo rmance of low -aspect -rat io ti res i s
part icularl y sensit ive to improp er i nflation
pr essu re. It i s th erefore importan t that low
aspect r atio tire s are infla ted to th e specifi ed
pr ess ure and that the inflation pressure is
regu lar ly che cked and maintained. Tir e pr es·
s ur es sh ould b e chec ked at l ea st once a
month and alw ay s before a lon g trip
<=> page 200, Checking tire pressure.
What you can do to avoid tire and rim
damag e
Low aspec t ratio t ires can be damaged more
easi ly by impact with potho les, cu rbs, gu llies
or ridges on the road, part icu larly if the tire is
underinflated .
I n o rder to m inimize the occu rrence o f impact
damage to the t ires of your vehicle, we recom -
Tires an d wheel s 211
mend that you observe the following preca u­
tions:
- Always ma inta in re commended inflation
pressures . Check your tire pressu re eve ry
2,000 miles (3,000 km) and add air if neces ­
sary.
- Drive caref ully 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, immediate ly inspect your
tires or have them inspected by the nearest
au thor ized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 m iles (3,000
km) for damage and wear. Damage is no t al­
ways easy to see . Damage can lead to loss of
air and under inflat ion, which could eventu­
ally cause tire failure .
If you believe that a
tire may have been damaged, rep lace the
tire as soon as possib le .
- These tires may wear more quickly tha n oth­
ers.
- Please also remember that, while these tires
de live r responsive handling, they may ride
less comfo rtably and make more noise than
other choices .
Reduced performanc e in winter /cold
season conditions
A ll ti res are designed for certa in p urposes.
T he low aspect ratio, ult ra h igh performance
tires originally installed on your vehicle are in­
tended for maxim um dry and wet road per­
formance and handling. They are not suitable
for cold , snowy or icy weather condi tions. If
you drive under those circumstances, you
should equ ip your vehicle w ith all-season or
winter tires, which offer bette r traction under
those conditions. We suggest you use the rec­
ommended snow o r all-season t ires specified
f o r yo ur vehicle , or thei r equivalent .
Refer to
<=> page 209 fo r more detailed infor­
mation regard ing winter tires .

Loosening
• Fit the wheel bolt wrench over the wheel
bolt and push it down as far as it will go .
• Close your grip aro und the
end of the
wrench handle for maximum torque and
turn the wheel bolts
counter-clockwise
about one single turn in the direction of ar­
row
¢ fig . 165.
Tightening
• Fit the wheel bolt wrench over the wheel
bo lt and push it down as far as it will go .
• Close your gr ip around the
end of the
wrench handle for max imum torque and
turn each wheel bolt
clockwise until it sits
t ight .
& WARNING
-Using force without cont rol to speed the
wheel change up can cause the vehicle to
slip off the jack and cause serious per­
sonal inj uries.
-Do not loosen the wheel bolts more than
one turn
before you raise the veh icle with
the jack. -Risk of inj ury!
(j) Tips
-Never try and use the hexagonal socket
in the handle of the screwdriver to loos­
en or tighten the wheel bolts.
- If a whee l bolt sits very tight, you may
find it easier to loosen by carefully push­
ing down on the end of the whee l bolt
wrench w ith
one foot only . As you do,
hold on to the car to keep yourse lf stable
and take care not to slip.
What do I do now? 223
Raising the vehicle
The vehicle must be lifted with the jack first
before the wheel can be removed .

• App ly the parking brake firmly to prevent
your vehicle from rolling unintentionally.
• Move the
selector lever to position P.
• Posit ion the jack below the door sill under
the
mounting point that is closest to the
wheel to be changed
¢ fig. 166.
• Extend the jack under the lifting poi nt on
the door sill until its arm is posit ioned di­
rectly under the lifting point ¢.&_ .
• Align the jack so that its arm ®¢
fig. 167
engages in the designated lifting point in
the door s ill and the movable base ® lies
flat on the ground. The base @ must be
ver­
tical
under the lifting point@.
• Wind the jack up further until the flat tire
comes off the ground ¢
_&.
The jack must be installed only at the places
indicated ¢
fig. 166 . Ther e is exactly one loca­
tion for each wheel. The jack must not be
positioned at any othe r location
¢ .& .
An unstable surface under the jack ca n cause
the vehicle to slip off the jack. Always provide .,._

~ Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel
bo lts
slightly .
~ Unscrew the alignment pin and insert and
t ighten the remaining wheel bolt s light ly
like the rest.
~ T urn the jack handle counter-clockw ise to
l ower the vehicle unti l the jack is fully re­
leased .
~ Use the whee l bolt w rench to t ighten al l
whee l bolts firmly <=>
page 222 . Tighten
them
crosswise, from one bolt to the (ap ­
proximate ly) opposite one, to keep the
whee l cente red.
Q;) Note
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
(D} Tips
Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or t ighten
the wheel bolts .
- Pull the reversib le b lade from the screw­
driver before yo u use the hexagonal
socket in the handle to t urn the whee l
bo lts .
- When mounting tires with
unid irectional
tread design
make su re the tread pat­
te rn is poi nted the r ight way
<=> page 226.
- The wheel bolts should be clea n and easy
to tu rn . Check for d irt and corrosion on
the mat ing s urfaces of both the wheel
and the hub. Rem ove a ll dirt from these
su rfaces before rem ounting the wheel.
Notes on wheel change
Please read the information <=> page 205 , 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 ve hicle.
Afte r you change a tire :
What do I do now? 225
-Check the tire pre ssure on the spare imme­
diately after mounting.
- Have the whe el bolt tightening torque
checked with a torque wrench as soon a s
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rim s, the wheel
bolt s are cor rectly tightened at a torque of
90 ft lb (120 Nm ).
- If you noti ce while changing a tire that the
wheel bolts are corroded and difficult to
turn , then they should be replaced before
you check the tightening to rque.
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
possible. Remount the whee l co ver.
Until then , dr ive with extra care and at re­
duced speeds.
A WARNING
- If you are going to equ ip your vehicle
w it h tires o r rims which differ from those
which were factory installed, then be
sure to rea d the information
