260 Tires and wheels
run flat tires. If run flat tires
are used, they must be in
stalled on all four wheels. Mixing tire types is not per
mitted.
@) 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 prof ile tires), then use
the spare tire for a short pe
riod of time only and drive
with extra care. Replace the
flat tire 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 w ith the local require
ments.
Uniform tire quality grading
- Tread wea r
- Traction AA A B C
- Temperature ABC
Quality g rades can be foun d where applicab le
on the t ire s ide wall between t read sho ulder
and maximum section width¢
page 254,
fig . 172 .
For example: Tread wear 200 , Traction AA,
Tempera ture A .
All passenge r ca r tir es must con fo rm to Feder
al Safety Req uirements in ad dition to these
grades.
Tread wear
T he tread we ar g rade is a c omparative r ati ng
b as ed on the wea r ra te of the tire when tes ted
u nder con tro lled cond itions o n a specifie d
government test course .
F o r ex am ple, a tire gr aded 1 S0 would wear
o n e and one h alf ( 11/ 2) times as well on the
government course as a ti re gr aded 10 0 .
T he re lative per forman ce of tires depen ds
up on the actu al cond itions of the ir use, h ow
ever, and m ay dep art s ignific antly from the
no rm due to va ria tions i n driving ha bits, se rv
ice p ractices and differe nces in road c haracter
ist ics and climate.
Traction
The tr actio n gr ad es, fro m hig hest to lowes t,
are AA, A, Ban d
C. Those grades represent t he
ti re 's ability to stop on wet pavement as
measured unde r cont rolled conditions on
specified g overnment test surfaces of aspha lt
and co ncrete. A t ire mar ked C may have poor
traction performance ¢
A.
Temperature
The temperature g rades are A (the highest),
B, an d C, represe nting the tire's resistance to
the generation of heat and its ab ility to dissi
pate heat when tested unde r controlled condi
t ions on a specif ied ind oor l abo rato ry test
whee l.

26 2 T ire s and wheel s
loss of control, crashes and serious per
sona l injuries. Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
wh ich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and traffic conditions. Never let the good ac
celeration of the winter tires and all-wheel
drive tempt you into taking extra r is ks. A l
ways remember:
- When brak ing, an a ll-wheel d rive vehicle
hand les in the same way as a front drive
vehicle .
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
canno t he lp under blac k ice condit ions.
@) For the sake of the environment
Use summe r tires when weathe r cond i
tions perm it. They are quieter, do not wea r
as quickly and red uce f ue l cons umption.
Snow chains
Snow chains may be fitted on ly to the front
wheels, and only to certain tire sizes . Ask you r
authorized Audi dealer on which tire sizes
snow chains can be used.
I f you are going to use snow chains, then you
must install them on the front wheels at
l east.
The snow chains must h ave low-profi le links
and must not be thicker than 0 .53 inch
(13 .5 mm), including the lock.
Remove wheel ce nte r covers a nd tr im dis cs
be fore putting snow chains on yo ur vehicle
q0 . For sa fety reasons cover caps must then
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 your veh i
cle o r instal ling them incorrect ly can in
crease the risk of loss of cont ro l leading to
se rious pe rsonal injury .
- Snow chains are available in different
sizes . Always make sure to follow the in
structions p rov ided by t he snow cha in
manufac turer.
- When driving with snow cha ins never
d rive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
@ Note
- Remove snow chains before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains dow n un necessa rily .
- Snow chains, which come into direc t con
tact with the whee l rim, can scrat ch or
damage it. Therefo re, make sure that the
s now chains are s uitably covered. Check
t he pos ition of t he snow chains after
driving a few yards and correct if neces
sary. Follow the inst ructions from the
snow chain man ufacturer when do ing so.
@ Tips
Where snow chains are mandatory on cer
tain roads, th is normally a lso applies to
vehicles with a ll-wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of w heel bol ts is matched to the
f ac tory installed rims. If different rims are fit
ted, the co rrect wheel bo lts 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
correct ly . .,..

274 What do I do no w?
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.
Never use the hexagonal socket in the han
dle of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversible b lade from the screw
driver before yo u use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
unid irectional
tread design
make sure the tread pat
tern is pointed the r ight way
¢page 274.
- The wheel bolts should be clea n 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 dirt from these
su rfaces before remo unti ng the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern p ointed in
the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a sp are tire w ith a tread pa tte rn
i nten ded for use in a specific direc tion, p lease
note t he following:
- T he direction of rotation is marked by an a r
row on the side of the tire.
- If the spare t ire has to be installed in the in
c orrec t direction, use the spa re tire only
tempor arily si nce the t ire will no t be able to
achieve its op timum performance character
istics with regard to aquaplaning, noise and
wear .
- We recommend tha t you pay particular a t
tention to this fact during wet weather and
that you adjust your speed to matc h road
condit ions. -
Replace the flat ti re with a new one and
have it insta lled on your vehicle as soo n as
possible to resto re the hand ling advantages
of a unidirectional tire.
Notes on wheel changing
Please read t he information ¢ page 254, New
tires and replacing tires and wheels
if you a re
going to use a spa re tire which is different
from the t ires 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 torque
c hecked with a torque wrench as soon as
possible by your author ized Audi dealer or
a qualified service stat ion.
- With steel and alloy wheel r ims, the wheel
bolts a re co rrectly tightened at a torque of
90 ft lb (120 Nm ).
- If you notice that the wheel bolts are cor
roded and difficult to turn while changing
a tire , they should be replaced before you
check the t ightening torque .
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
po ssible . Remount the wh eel cover.
Until then , dr ive with e xtra care and at re
duced speeds.
A WARNING
= -
- If you are going to equ ip your vehicle
with tires o r rims which differ from those
which were facto ry installed, then be
s ure to read the information¢
page 25 4,
New tires and repla cing tires and
wheels.
- Always m ake s ure the dam age d wheel o r
even a flat tire a nd the jack and tool ki t
are properly secu red in the luggage com
pa rtment and are not loose in the pas
senger compartment.
- In an accident or sudden maneuver they
could fly forwa rd, injuring anyone in the
veh icle.
