Wheels
bolts and a special procedure. You must never
repair or disassemble them ¢
.&..
A WARNING
Wheel bolts that are tightened or repaired in
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi
cation, refer to ¢
page 348, Finishing .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inter tires significantly improve the vehicle's
handling when driving in winter conditions. Be
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac
tion on ice and snow.
.,. Use winter t ires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lowe r with winter tires
q ,&. . An
authori zed Audi dealer or authori zed Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after installing wheels
¢page 327.
The effectiveness of winter tires is reduced great
ly when the tread is worn down to a depth of
0 .16 in (4 mm) . The characteristics of winter
tires also decrease great ly as the tire ages, re
gardless of the remaining tread .
A WARNING
-Never drive faster than the maximum per
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
332
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, only
winter tires w ith the ~ symbol are permitted .
Snow chains
Snow cha ins not only improve the driving in win
ter road condit ions, but also the braking.
.,. Only install snow chains on the
front wheels .
This applies a lso to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when driv
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi deale r or author
ized Audi Service Facility to see if you may use
snow chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 in (13 .5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with
out snow. Otherwise , you could impair driving
ability and damage the tires .

A WARNING ,~
Using incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i
dent.
(D Note
Snow chains can damage the r ims/wheel cov
ers* if the chains come into d irect contact
w ith them. Remove the wheel covers* before
hand . Use coated snow chains.

Low aspect ratio tires
Your Aud i is facto ry-equipped with low aspect ra
tio ti res. These t ires have been tho rough ly tested
and been se lected specifically for yo ur model for
their superb per formance, road feel and handling
under a variety of driving conditions. Ask your au
thorized Audi dealer for more details .
The low aspect ratio of these t ires is indica ted by
a numera l of
55 or les s in the tire's size designa
tion. The numeral represents the ratio of the
tire's sidewall height in r elation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more.
The performan ce of low-aspect- ratio tire s is par
ticularl y sensiti ve to improper inf lat ion pres
sure . It is therefore impo rtant that low aspect
ratio tir e s are infl ated to the specified pressu re
and tha t the inflation pr essure is regularly
checked and maint ained . Tire pre ssure s should
be check ed at lea st once a month and alwa ys
b efore a long trip<=:>

What you can do to a void tire and rim
damage
L ow aspect rat io tires can be damaged more easi
l y by impact with potho les, cu rbs, gull ies or
r idges on the road, pa rtic ularly if the tire is un
derinflated.
Wh eel s
In order to min imize the occurrence o f impact
damage to the tires of your vehicle, we recom
mend that you observe the following precau
t ions:
- Always maintain recommended inflation pres
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads with potholes, deep
gu llies or ridges . The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest au
thorized 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 not always
easy to see . Damage can lead to loss of a ir and
underinflation, wh ich could eventually cause
tire fa ilu re . If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos
sible.
= These tires may wear mo re quickly tha n others.
- Please also remember that , while these tires
de live r responsive ha nd ling, they may ride less
comfort ably and make more noise t han other
choices .
Reduced performance in w inter /cold season
conditions
All tires are des igned for certai n pu rposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for co ld, snowy or
icy weather conditions. If you drive under those
c ircumstances, you should equip your vehicle
with all -season or winter tires, which offer better
tract ion under those conditions . We suggest you
use the recommended s now or a ll-season tires
spe cified for your vehicle, o r their equiva lent.

t ion regard ing winter tires.
