Wheels
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 tightening specifi-
cation, refer to c:>
page 231, After changing a
wheel.
-
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 repair
facility.
Never
repair or disassemble rims
yourself, because this increases the risk of
an accident.
Winter tires
Winter 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
traction
on ice
and
snow.
.., Use
winter tires on all four wheels
.
..,
Only use winter tires that are approved for your
vehicle.
..,
Please note that
the
maximum permitted
speed may be lower with winter
tires
c:>
.&,.
Your authorized Audi dealer or authorized re-
pair
facility can inform you about the maximum
permitted speed for your tires .
..,
Check the tire pressure after
installing
wheels
c:>
page 219.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0 .1S7 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages,
re-
gardless of the
remaining
tread
.
A
WARNING
-
Never
drive faster than the maximum
per-
mitted speed
for
your t ires.
This could
cause
the tires to
heat up
too
much
.
This
increases
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 provide 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 win-
ter tires w ith the
&
symbol may be permit-
ted.

Snow chains
Snow chains improve traction in the snow
.
..,
Only install snow chains on the
front
wheels.
This applies also to vehicles with all wheel
drive* .
..,
Check and correct the seating of the snow
chains if necessary after driving a few feet.
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)
.
Snow chains not only improve the
driving
in win-
ter
road
conditions, but also
the
braking.
Use
of snow chains
is
only permitted with certain
rim/tire combinations
due to
technical
reasons.
Check
with
an
authorized Audi dealer or author-
ized
repair
facility to
see if you may use snow
chains
.
Use fine-mesh
snow
chains. They
must not add
more than 0.53 inch (13.S mm) in height, includ-
ing
the chain
lock.
You must
remove
the chains when driving on
roads
that are
free
of
snow. When
roads are free
of snow, snow chains can impair handling
and
