Cleaning and protec tion
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.,. Wash the wheels with a sponge or hose
brush every other week.
.,. For deep clean ing afterwards, use o nly a
ded icated acid-fr ee cast alloy wheel cleaner .
.,. Rub a coat of liquid wax onto the rims every
three month. Be sure to reach and treat all
pa rts of the rim.
To preserve the decorative appearance of the cast alloy wheels, som e special care is neces­
sa ry. In addi tion to road d irt and salt, brake
dust is a lso co rrosive . If left on fo r too long,
brake d ust can cause pitt ing.
Use only spec ia l
acid-free cleaners formulated
fo r alloy r ims. Safe produc ts are ava ilab le at
yo ur Audi dealer. Never leave the cleane r on
the rims longer than specified on the label. If
not rinsed off prompt ly, the acid con tained in
some cleaners can attack the threads on the
whee l bolts .
Never use abrasive o r metal po lis hi ng clean­
ing agents .
If the protective coating has been
c h ipped, e.g . by kicked up road dirt, to uch it
u p as soon as possible .

recommend using only these tires because
they meet the highest standards regard ing
sa fety and driving character istics when used
correctly . Your authorized Audi dealer will
gladly provide you with more information .

_&. WARNING ,-=
-Using incorrect o r unmatched tires and/
or wheels or improper tire and wheel
comb inations can lead to loss of control

coll is ion and serious personal inj ury.
- Always use tires, 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 fail suddenly , especially at high
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 mo unt used tires on your veh icle if
you are not sure of thei r "previous histo­
ry." O ld used tir es may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.
- All four whee ls must be fitted with radial
tires of the same type, size (rolling cir­
cumference) and the same tread pattern .

chains because t he vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severe ly dam­
age the wheelhouse and other parts of
the veh icle.
@ Tips
Where snow cha ins 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 installed r ims. If different rims are fit­
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used . This ensures that wheels are fitted
secure ly and that the brake system f unctions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same mode l
¢page 285.
A WARNING
Imprope rly tig hte ned or maintained whee l
bolts can be come loose causing loss of
contro l, a co llision and serious persona l in­
jury .
- Alw ays keep the w heel bolts and the
th reads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the w heel h ubs. They can
become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tightening
torq ue for the wheel bo lts to reduce the
Tire s an d wheel s 255
risk of a wheel loss. If the tightening tor­
que of t he wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tighte ning torque is
too h igh, the wheel bol ts and threads
can be damaged and the whee l can be­
come loose.
(I) Note
The specified torque for the whee l bolts is
90 ft lb ( 120 Nm) wi th a tole rance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. Afte r cha nging a whee l, the torq ue
must be checked as soon as possible wi th a
torque w rench -prefe rably by an au thor­
ized Audi dealer or qualif ied workshop .
Low aspect ratio tires
Your Audi is facto ry-eq uipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling u nder a variety of driving cond i­
tions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation . The numeral rep resents the ratio
of the t ire's sidewall height in relation to its
t read width ex pressed in pe rce ntage. Conven ­
tiona l tires have a he igh t/w idth ratio of 60 or
more.
The performance of low-aspe ct-ratio tire s is
particularly sensitiv e to improper infla tion
pres sure. 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 checked and maintained. Tire pre s·
sures should be checked at least once a
month and always befo re a long trip
