run flat tires. If run flat tires
are u sed , they must be in
stalled on all four wheels. Mixing tire types is not per
mitted.
(D Note
-For technical reasons, it is not generally possible to
use the wheel rims from
other vehicles. This can hold
true for wheels of the same
vehicle type.
- If the spare tire is different
from the tires that you have mounted on your vehicle
(for example winter tires or
wide profile tires), then use
the spare tire for a short pe riod of time only and drive
with extra care. Replace the
flat t ire with the tire match
ing the others on your vehi
cle as soon as possible.
- Never drive without the
valve stem cap. The valves
could get damaged .
@) For the sake of the environment
Dispose of old tires in accord
ance with the local require ments.

Uniform tire quality grading
- Tread wea r
- Traction AA A B C
- Temperature AB C
Quality g rades ca n be foun d where applicab le
on the t ire s ide wall between t read sho ulder
and maximum section width

For example : Tread wear 200, Traction AA,
Temperat ure A .
All passenge r ca r tir es must con form to Feder
a l Safety Re quirements in add ition to these
grades.
Tread wear
T he tread wear g rade is a c omp arat ive rating
based on the wear ra te of the tire when tes te d
u nder con tro lled conditions o n a specifie d
government test course .
F o r example, a tire gr aded 1S 0 wo uld wear
one a nd one h alf ( 11/ 2) times as well on the
governmen t course as a ti re g raded 100 .
T he re lative perfo rman ce of tires depe nds
up on the actu al c ondition s of the ir u se, how
ever, and m ay depa rt s ignificantly from t he
no rm due to va ria tions i n driving ha bits, se rv
ice p ractices and differences in road c haracter

measured u nder cont rolled conditions on
specified government test surfaces of aspha lt

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed rims. 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 functions
correctly .
In ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
~page 294.
_& WARNING
Improperly tig htened o r maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tighten ing
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the veh i
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be
come loose.
@ Note
The spec ified torq ue fo r the wheel bo lts is
90 ft lb (120 Nm) w ith a toleran ce of± 7,4
ft lb(± 10 Nm). Torque wheel bo lts diago- nally
. After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb perfo rmance, road fee l
and hand ling under a variety of d riving cond i
tions . As k your au thor ized A udi dealer for
more de tails .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The nume ra l represen ts the ra tio
of the tire's sidewall height in relation to its
tread width expressed in percentage . Conven
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low- aspect-r atio tires is
p ar ticu la rly s ens iti ve to improper infl ation
p re ss ure. I t is th erefore im portant th at low
as pect ratio tires are inflated to the specified
pressure and that the inflation pressu re is
r e gularl y che cked and mainta ined. Tir e pre s
su res should be ch ecked at least onc e a
month and alwa ys bef ore a long trip
~ page 249, Checking tire pressure.
What you can do to a void tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes, curbs, gull ies
o r r idges on the road, pa rticularly if the tire is
u nderinfla ted .
In order to minimize the occurrence of impact
damage to the tires of you r vehicle, we recom
mend that you observe the follow ing p recau
tions:
- Always ma inta in recommended inflation
pressures. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces
sary .
- Dr ive carefully on roads with potholes, deep
gullies o r ridges. The impact from dr iv ing ..,.

Putting on the spare wheel
"'Lift the spare wheel and ca refully slide it
over the alignment pin to guide it in place
¢ (D .
"' Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel
bolts
slightly.
"' Remove the alignment pin and insert and
t ighten the remaining wheel bolt s lightly
like the rest .
"'T urn the jack handle counte r-clockw ise to
lower the vehicle unt il the jac k is f ully re
l eased .
"' Use the whee l bolt wrench to tighten a ll
whee l bolts firmly
¢ page 274. Tighten
them
crosswis e, from one bolt to the (ap
proximate ly) opposite one, to keep the
wheel cen tered.
When removing or install ing 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 blade from the screw
driver before you use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
un id ire ctional
tread design
make s ure the tread pat
tern is poi nted the right way
¢ page 277.
- The wheel bolts should be clean and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the h ub. Remove a ll dir t from these
su rfaces before remo unting the wheel.
What do I do now? 277
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Usi ng a spa re ti re with a tre ad patte rn
intended for use in a specific direction
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection, please
note the following :
- The d irect ion of rotation is marked by an ar
row on t he side of the ti re .
- If the spare tire has to be installed in the in
correct direct ion, use the spare tire only
temporarily s ince the t ire will not be able to
achieve its optimum performance cha racte r
istics w it h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu lar at
ten tion to th is fact during we t wea ther and
t ha t you adjust your speed to match road
conditions .
- Replace the fl at t ire wi th a new one and
have i t installed on your vehicle as soon as
possible to restore the hand ling advantages
of a un idirectional tire .
Notes on wheel changing
Please read the information¢ page 257, New
tires and replacing tires and wheels
if you a re
go ing to use a spare tire wh ich is different
from the tires on you r vehicle .
After you change a tire:
- Check the tire pre ssure on the spare imme
diately after installation.
- Have the wheel bolt tightening torqu e
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 rims , the wheel
bolts are cor re ctly tightened at a torque of
90 ft lb (120 Nm ).
- If you notice that the wheel bolts are cor
roded and diff icult to turn while changing
a tire , they should be replaced before you
check the t ightening torque. .,,.

A WARNING
-
- If you are going to equip your vehicle
with t ires or rims wh ich d iffer from those
wh ich were factory installed, then be
sure to read the informat ion
c::> page 257,
New tires and replacing tires and
wheels.
- Always make sure the damaged wheel or
even a flat tire and the jack and tool kit
are properly secured in the luggage com
partment and are not loose in the pas
senger compartment.
- In an accident or sudden maneuver they
cou ld fly forward, inju ring anyone in the
vehicle.
- Always store damaged wheel, jac k and
tools secure ly in the luggage compart
ment. Otherw i5e, in an acc ident or 5ud
den maneuver they cou ld fly forward,
causing injury to passengers in the vehi
cle .
