different tire speeds. For this rea­son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
&_ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
Wheels
-Only use tires that are more
than 6 years old when abso­ lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear .
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear. ..

Rims
R ims with a bolted rim r ing * or w it h bolted whee l
covers * consist of mu ltiple pieces . These compo ­
nents were bolted together using specia l bolts
a nd a special procedu re. You must not repair o r
d isassemble th em¢ ,&..
_& WARNING
Whee l bolts tha t are t ightened o r repa ire d in­
correctly can become loose and resul t in loss
of vehicle control, which increases the risk of
an acc ident. For the correct t ightening specif i­
cat ion, refer to¢
page 241, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the whee l hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
232
- Always have damaged rims repaired by an
author ized Audi dealer or authorized Audi
Serv ice Facility. Neve r repa ir or disassemb le
r ims you rself, because this increases the risk
of an accident.
Winter tires
Win ter tires significantly improve the vehicle's
handling when dr iv ing in winter conditions. Be­
ca use of their const ru ct ion (w idth, compou nd,
t read pat te rn), summer t ires provide less t rac­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. Onl y use winter tires that a re approved fo r yo ur
veh icle.
.,. Please note that t he maximum permit ted
speed may be lower with winter tires¢.&_ . An
authorized A udi dealer or authorized Audi
Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after insta lling wheels
¢ page 227.
The effectiveness of winter tires is reduced great­
l y when the tread is worn down to a depth of
0 .157 in (4 mm). The characteristics of winter
tires also decrease g reatly as the tire ages, re­
gard less of the rema ining t read .
_& WARNING
-
-Never d rive fas ter than the max imum pe r­
m itted speed for your tires. This could c ause
the t ires to hea t up too m uch. T his increases
the risk of an accident because it can cause the t ire to burst.
- Always ada pt your driving to the road and
traffic conditions. Drive carefu lly and reduce
your speed on icy or slippery roads. Even
winter t ires can lose tract ion on black ice.
@ For the sake of the environment
Reinsta ll summer tires a t the appropriate
time, beca use they provide better handling
when roads are free o f snow and ice. Summer
tires cause less road no ise, tire wear and fuel
consumpt ion.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire w ith a t read pattern in­
tended for use in a specif ic direction, please note
the following:
- The direction of rotation is marked by an
arrow
on the side of the tire.
- If the spare tire has to be inst alled in the inco r­
rect direction, use the spare tire on ly tempora ­
r il y since the tire will not be a ble to ac hieve its
optimum performance characterist ics with re­
gard to aquaplan ing, no ise and wear.
- We recommend that you pay part icu lar atten­
tion to th is fact d uring wet weather and that
you adjust your speed to matc h road condi­
tions .
- Rep lace the flat tire w ith a new one and have it
installed o n your veh icle as soon as possib le to
restore the hand ling advan tages of a un id irec­
t ional tire.
